Description
The present research dealt with the numerical simulation of nanofluid flow in a pillow-plate heat exchanger. Al2O3-water nanofluid and water are considered to be working fluids. A two-phase mixture model was used for flow simulation. The effect of the geometry properties on the hydrodynamic and thermal performance of the heat exchanger was studied. Next, the focus was placed on using nanofluids as a working fluid in the heat exchanger. Dimensionless pressure drop, Nusselt number, and dimensionless temperature are analyzed. The results indicate that heat exchangers with nonlinear hole layout have a higher Nusselt number up to 25 percent. Furthermore, bigger holes in pillow plate heat exchangers lead to higher pressure drop. In addition, using nanofluids as working flow improves thermal efficiency up to 10 percent and increases pressure drop up to 7 percent.
