CFD simulation for opaque ventilated facades in hot arid climate based on literature review design parameters

Abstract

In this paper, computational fluid dynamics (CFD) simulations were conducted to analyse the design parameters found in the literature review that influence the performance of an opaque ventilated façade (OVF) and provide a baseline prototype for future parametric optimisation of novel OVFs. The baseline prototype is created by combining the most common OVF geometrical solutions discovered in the literature and applied in Riyadh, Saudi Arabia, which is an extremely hot and arid region. The CFD simulation results indicate that airflow velocity within the OVF’s cavity has the most significant effect on its thermal performance in hot, arid climate areas.
