A numerical investigation of counter flow heat exchanger in a particular tube in tube heat exchanger with reversing the flow is investigated in this paper. The investigation includes the heat transfer and the pressure drop in the heat exchanger considering water as a fluid. Many researchers have reported regarding the enhancement of counter flow heat exchangers altering the fluid temperature and using different fluids. Here to foresee the outcome of the heat exchanger in terms of temperature change and pressure drop due to variation of temperature and mass flow rate a CFD program fluent has been used. A set of CFD simulation is carried out for the double pipe counter flow heat exchanger and after validating the methodology of CFD analysis the effects are established. The experimental results available in the literature [8] are compared with CFD fluent simulation results in ANSYS 14. We have got a better comparison with the previous results with net average temperature of 323.80K using aluminum as a material of construction and viscous k-ε model for the flow domain. However there is a very less marginal error of less than 2% comes in the simulation. The values and the results are case responsive to the turbulence model section.

Keywords- 3D CFD modeling, RNG K-epsilon model, Temperature distribution, velocity distribution, pressure drop.
