The various processes in dairy industry include pasteurization, cream separation, homogenization, chilling of milk and packaging of milk and value-added products. Currently, the thermal and electrical demand required for various dairy processes is satisfied by conventional fuels like furnace oil, coal, natural gas and electricity. The total electricity consumption is about 53% of total demand, whereas the rest of demand is satisfied by natural gas, furnace oil, coal which accounts for 22 to 25% respectively. These all non-conventional resources are going to deplete in next 3 to 4 decades, so there is a need to switch the use of conventional resources for process heating and cooling to non-conventional.

A review on cleaning mechanism of solar photovoltaic panel

2017 International Conference on Energy, Communication, Data Analytics and Soft Computing (ICECDS), 2017

To harness their designed capacity to its fullest, they need to be cleaned periodically, usually with water. Due to water scarcity in some area, cleaning becomes difficult, challenging and subsequently costly. Solar Photovoltaic conversion technique of is largely used as a pioneer and efficient conversion of solar energy. Many factors govern Solar Photovoltaic energy conversions efficiency like solar intensity, the area of the module, semiconductor, tracking mechanisms, dust, and dirt etc. Nowadays among these factors dust and dirt has become crucial for research since they have a significant effect on conversion efficiency. If proper cleaning mechanisms are used then, it may show about 25% improvement in output energy or about 15 to 20% enhancement in conversion efficiency. Hence, rigorous study of SPVC automated cleaning mechanism is vital. This paper discusses a comprehensive overview of dust problem and the recent developments made on automated cleaning system of solar photovoltaic modules which gives a brief overview of techniques like electrical, mechanical, chemical and electrostatic. The main objective of the study is to review the literature on solar photovoltaic module automated cleaning techniques for identifying research gaps in the automated cleaning systems.

This multi-stage process is performed using abrasive tools fed against the bore with simultaneous rotary and oscillatory motion. To have process robustness with acceptable dimensional accuracy and surface quality, the various process parameters have to be studied deeply. This paper aims to improve the quality of honing process by optimizing and analyzing the cylinder liner surface roughness which is influenced by various process parameters during honing. Conducting the experimental runs according to the design of experiment and analyzing the results which are finally validated through confirmation experimentation.

Numerical simulation and experimental validation of solar greenhouse dryer using finite element analysis for different roof shapes

The heated space is retained within the enclosure of greenhouse. This phenomenon is called as greenhouse effect. The important role played during the greenhouse effect phenomenon are atmosphere, insulating roofs, walls, etc. The current study focuses on the numerical and experimental validation of Solar Greenhouse which is utilized for drying phenomenon. The numerical simulation is performed using Finite Element Analysis method. The various roof shapes have been incorporated to have emphasis on maximum solar gain to drying phenomenon.

Competition has increased dramatically. Customers focus on product quality, product delivery time and cost of product. Because of these, a company has to develop design and 3D modeling software to meet the requirement of the customers. Normally, the heat exchanger design calculations are required with assumed data. Iterative procedure is used to correct the assumed data to optimum solution. But it requires lot of calculation work which is time consuming. The computer software will play important role to eliminate the problem of iterative calculations and 3D modeling of heat exchangers. To design for better quality , it is necessary first what quality means and how it is measured. A product or process that is reliable, and that performs its intended function is said to be a quality product. The degree to which something meets or exceeds the expectations of its consumers.
