Optimization and simulation of solar parabolic collector with different absorber tubes and working fluids

In this paper an evolution model constructed to step up the collector efficiency. Experiments are conducted on fabricated Parabolic solar thermal collector (PSC) by telling three different absorber tubes (Copper tube coated with Ni-Al, vacuum tube and Nano fluid tube) and three heat transfer fluids (water, Ethylene Glycol +Water(60:40) and copper oxide Nano particles Nano fluid)one at each time. The setup was installed on SVU College of engineering building at Tirupati of 13.6288° N latitude and 79.4192° E longitude. In experimentation, heat transfer fluid temperature was collected at every one hour gap. With help of this temperature and incident radiation on aperture area, the maximum and minimum efficiencies of collector are evaluated in a day. Analysis is done on experimental results by using Factorial method and ANOVA. The optimized combinations are identified. Here Simulation is done for the purpose of judging the utilization of resources, hence the Optimized combinations of heat absorber tubes and Heat transfer fluids are used in Simulink of Mat lab. Finally observed that fabricated model of solar thermal collector has had improved efficiency.
