Thermal Performance Analysis Of the Solar Water Heater With Circular And Rectangular Absorber Fins

Abstract

The topic of the research of solar energy has become a matter of great concern due to energy crisis all over the world. Several techniques have been implemented for heat transfer augmentation in heat transfer device. The implementation of the micro fin tube is one of the promising heat transfer enhancement methods since the technique offers an excellent improvement of heat transfer rate. Here fins played its major part in the enhancement of the temperature of the solar water heater so we implemented fins for the purpose to obtain better temperature output. The main objective of the experiment is to maintain the velocity at the outlet and the better outlet water temperature by selecting the correct shape and measurement of fins. Maintaining the pressure drop, increasing the heat transfer rate by increasing the area of the tube is also the main motto of the conducting this experiment. The expected temperature enhancement lies in the range of 16 to17 ºC. As the fins placing inside the thin water tube creates water hindrance,so by placing the appropriate fins regarding its size and shape we have definitely come across the problem of velocity drop as well as pressure drop inside the tube of the solar water heater.
