Numerical Investigation of Heat Transfer in Car Radiation System Using Improved Coolant

Abstract

In the this study , numerical analysis  of heat transfer in the radiation system of the car has been investigated by using pure water and water with nano-fluid. ANSYS fluent version 16.1 has been conducted to carry out the simulation process  using Computational Fluid Dynamic (FCD) approach. This study has been validated with experimental results and based on the simulation results the error was 8% when applying the same boundary condition. And the validation process was carried out for the flow rate with Nusselt number in both concertation 0.7 % and 1 %. Based on numerical analysis, the Nusselt number has been increased by increasing nano particle concertation. Increased number of Nusselt causes the enactment of the heat exchanger. The previous experimental data show that the heat transfer of the nanofluids was based highly on the concentration of nano particles, the flux conditions and the weak temperature-dependent heat transfer conditions.
