Comparison heat transfer between finn solar water heater pipe and normal solar water heater pipe using cfd

摘要

The development in the world of energy conversion has been progressing especially in the field of applying renewable energy resources related to the Sun.The application is not only in the world of industry but includes the smallest part or household.One application of solar energy resources is solar water heater.Solar water heater is a tool that utilizes heat from the collector to heat water flowing in tubes that are expected to increase the fluid exit temperature.In this study an increase in the efficiency of solar water heater is done by increasing the surface area of the pipe by adding fins on the side of the pipe which are expected to increase the temperature of the fluid out of the pipe that is plain or does not have fins.With the simulation method using CFD software obtained an increase in pipe exit temperature by 0.9%.this shows that in a part of a double-finned pipe,it does not significantly affect the increase in fluid exit temperature.
