Numerical investigation of effects of PFCDs geometry on the flow field and heat transfer of air flow in solar chimney power plant

Abstract

In this paper, the effects of PFCDs geometry on the flow field and heat transfer are studied when they are used in the solar chimney. For this purpose, the SST/k − ω model, has been employed. The simulation results have indicated that the SST/k − ω model has a close agreement with the available experimental data. Results are performed in terms of mean velocities and global parameters, i.e., strain rate, Reynolds shear stress. Results from numerical simulations, using different configurations, show that the flow field and the corresponding heat transfer distribution are affected by PFCDs geometry. Also, PFCDs position affects the flow structure and consequently the heat transfer. Heat transfer rate experiences several extreme as a result of fluid
