Numerical Investigation of double pipe heat exchanger with different nanofluids
Abstract
The study represents an enhancement of heat transfer using different nanofluids containing nanoparticles (Al2O3, Cu, Ag, TiO2, SiO2, Fe) Volume fraction (0.02≤ϕ≤0.05). Numerical simulations are conducted using CFD (Computational Fluid Dynamics) and the model is generated using Solid works. The governing equations are solved using a SIMPLE technique and discretized using finite volume approach. The results show that the heat transfer rate increases with the increase of the flow rates, also it has been observed that heat transfer rate increases with increase of operating temperature and also by the concentration of nanoparticles.
