Abstract- Double pipe heat exchanger is simplest form of heat exchanger containing two coaxial pipes, one inside another. Hot fluid flows inside the pipe and cold fluid flows in the gap between the two pipes, the surface of the inner pipe is the heat transfer surface which is responsible for the heat transfer between the fluids. This analysis based on the computational fluid dynamics where air to air heat exchanger utilized in cross linear concentrated solar power system CL-CSP. The following research is under process at RGPV BHOPAL. The study is based on the analysis of temperature distribution of heat transfer fluid (air), comparison of effectiveness of heat exchanger with and without insulation, and flow behavior of HTF in both hot and cold side of pipes. CFD simulations have been performed on the Ansys 16.0. K-? turbulence models have been assessed and model has shown to provide more accurate results for temperature prediction.
