This research work focuses on the design of a glass pulverizing machine which has a drop loading hopper with a retractable cover to prevent particle escaping the chamber, a horizontally oriented steel shaft to which is attached 3 steel blades separated at 120 0 to their centre, all enclosed in a cylindrical crushing chamber with perforations of predetermined sizes that allows the passage of pulverized glass particles through it and a 1hp high speed motor which drives the shaft. The shaft-blade assembly was separated from the internal walls of the cylindrical crushing chamber by a clearance of 10mm to enhance crushing to finer particles and forced passage of the glass particles through the perforations. The drop loading of glass through the hopper from above reduced the crushing force of the blades, energy usage of the machine and ensured retraction of the glass particles. Results from the testing of the machine showed that fine glass particles as small as 20μm were obtained and the glass crushing capacity was 230kg/h.

This study investigates the optimization of wind turbine placement using historical SCADA data, computational fluid dynamics (CFD), and Differential Evolution (DE) algorithms. We analyzed a comprehensive wind turbine dataset, which included wind speed, active power, theoretical power curves, and wind direction data. The analysis revealed a direct relationship between wind speed and power output, with discrepancies observed at both low and high wind speeds due to system inefficiencies and turbine power limits. The Frandsen wake model was employed to account for the wake losses, while the Differential Evolution algorithm was used to optimize the turbine positions to develop an optimal layout for 100 turbines within a minimum area of 21.6 km², aiming to minimize the wake effects and maximize the energy production. The results demonstrate that proper turbine alignment and spacing significantly improve the efficiency, allowing the turbines to operate closer to their theoretical maximum efficiency. The findings highlight the critical role of integrating historical wind data with CFD simulations to optimize turbine placement and performance. This work offers a valuable framework for future windfarm designs, emphasizing the benefits of data-driven approaches in maximizing renewable energy generation and operational efficiency.

This work entailed the use of advanced predictive machine learning models for optimal power output, reduced uncertainty, optimal resource planning, and a notably high degree of alignment with peak demands for energy for efficient power production from solar radiations. Models were generated by employing machine learning algorithms for data evaluation. The direct in-plane irradiance has the strongest correlation (1.00) with PV output, according to the results. Additionally, it indicated that the value of R 2 : 0.999567 of the Random Forest Regression was higher than all other regression models and the least Mean Squared Error (MSE) and Mean Absolute Error (MAE), 17.130680 and 2.28139, respectively. On the other hand, the Linear Regression's Mean Squared Error (MSE), R 2 , and Mean Absolute Error (MAE) values are, respectively, 20.645271, 0.999478, and 3.16270. Random Forest Regression is a stronger forecasting model because of its higher R 2 value, which also helps to explain variations in PV power output.

In this work, the effects of varying wind angles and increasing concentration on air pollutant dispersion from cooling towers to urban area were investigated using computational fluid dynamics (CFD) software; OpenFOAM and the modified k-ω SST turbulence closure to acquire the steady-state flow field based on Reynolds Averaged Navier-Stokes Equation (RANS) approach. The results showed that varying the wind direction for the wind velocity profile from (1 0 0) to (Cos30 0 Sin30) and (Cos45 0 Sin45) affected the pollution dispersion across the urban area with the worst scenario being (1 0 0). In addition, reducing the diffusivity constant (Dt), thus increasing the pollution concentration, from 0.02 to 0.001 increased the pollution transport across the urban area considerably. This research shows the benefit of applying CFD approach toward managing the challenges of air pollution dispersion.

The overall performance envelopes of most of the shale shakers have been decided empirically. Systematic empirical research of complete shale shakers are not easy and are costly to develop because of the excessive rate of flow of drilling fluid and coarse debris conveyed via the screener. Beyond its use in the oil and gas industry, shale shakers could be utilized in agriculture separation of biomass and fluids. The present design considered operational parameters such as solid conveyance, spring length, amplitude and frequency of vibration, throw index and screen slope. The designed shale shaker comprises of a vibrating offset mass connected via a pulley system to an electric motor. An open V-belt, balata type material was specifically selected for effective grip. Four springs; two on each side that are encased by spring cups were attached to the shaker frame. Test and analysis carried out on the prototype showed that the oscillating motion of the mud bath caused the coarse masses to move upward and forward on the screen, while the fluid sift through the filter medium attaining filtration ratio to particle diameter of 4:1. As coarse particles size increased, the filter ratio increased. As vibration frequency increased, there was a corresponding increase in throw index which is an indication of the move activity of particles. There was a direct relationship of proportionality between the throw index, the vibration frequency, and amplitude of the mud particles. With attempt geared toward lowering the experimental costs while maintaining efficiency, the shale shaker was designed.

The Pneumatic jack was fabricated to ease the use of handling and minor complications from handling the conventionally operated jack. Two basketballs are used as the bags for the pneumatic jack, and these basketballs are encased in a sheet metal casing. The metal casing protects the ball from puncturing, as rusted metal parts can be found beneath some cars. Using basketballs as the bags for the jack makes it cost effective for production. The air compressor is connected to a battery, charge controller and solar panel, and the hose is connected to the basketball valve. An air pressure of 0.241 N/mm 2 on each basketball can lift a mid-size sedan with an average weight of 1300kg off the ground to a height of 160mm in less than a minute. The fabricated pneumatic jack can be utilized in lifting loads in any topography with little or no human effort which is an advantage over the conventional jacks.

Four parameters including Temperature, Punch displacement, Billet radius and Time were considered in the course of the study. It was observed that the higher the percentage reduction in area, the higher the temperature increase during the extrusion process. The effect of an increasing billet length showed a corresponding increase in the extrusion pressure, whereas, the extrusion pressure increased as extrusion ratio increase. Extrusion speed varied directly with metal temperature and pressure developed within the container. However, the extrusion force depended on the flow stress of the billet material, extrusion ratio, friction condition between the billet and container, friction condition of the die material interface, initial billet temperature and the extrusion speed. Hence, this study becomes essential for the selection of the right parameters for optimal extrusion process of metals.

The large population of Nigeria and the nonenforcement or implementation of any viable or sustainable plastic waste recycling measures ensures that huge quantities of plastic wastes are released daily into the Nigerian environment. In this work, a naturally aspirated stove for domestic use, that burning plastic waste as fuel, was designed, locally fabricated and tested. The eco-stove measures 0.25m by 0.864m. It consists of an insulated preheating and burning chamber, an air inlet, a chimney, a convergent-divergent conical body assembly and a fuel feeding inlet. The plastic waste was processed by first physically inspecting them and removing dirt and all entrapped moisture. Thereafter, they were shredded by a purpose-built shredding machine into fine particles. The stove preheating and burning chamber was then loaded with 0.5kg of charcoal. The charcoal was then burnt until the chamber reached a stable temperature of about 450 0 C-500 0 C as measured by a base metal (E-type) thermocouple to ensure that the ignition temperature of most plastics have been reached and exceeded. The shredded plastics were then fed into the burning chamber. After ignition, the temperature of the flame produced was measured and also 5kg of water was boiled the result shows that the combustion temperature of the flame produced by the plastic reached 700 0 C in less than 20 seconds as measured by the thermocouple used. The colour of the flame was yellowish-green. 5kg of water boiled to reach 100 0 C in 22 minutes. This shows that the eco-stove can be used for cooking. Moreover, the smoke produced were not sooty after passing through the chimney.

The MATLAB program was effective in simulating and predicting the effect of heat transfer rate and change in internal energy of the billet and tooling materials on the extrusion load during the backward cold cup extrusion process. It was inferred that as the change in internal energy of the billet, die material and the heat transfer rate increases the extrusion load also increases. There was a direct proportionality relationship between the change in internal heat of the billet and the heat transfer rate during the extrusion process. The use of MATLAB simulation for the extrusion process saved time and cost in the analysis and prediction of the extrusion variables compared to carrying out physical experiment. This study is significant in designing and selecting adequate extrusion machine and tooling as well as carry out an efficient extrusion
