Computational Study of the Heat Ventilation on The Attics of Buginese Houses

Abstract

Numerical investigation of heat ventilation on the traditional house attic of Buginese in a hot and humid tropical climate was carried out using computational fluid dynamics models. The Navier-Stokes (RANS) modeling approach is used for numerical investigations. Determined the breakdown of steady-state conditions by using SolidWorks Flow Simulation software. Based on various flow simulations, numerical results obtained for temperature distribution, airflow patterns, indoor turbulence characteristics, Dynamic pressure, Density, and Turbulent Viscosity are presented. Using numerical results, it is known that the stack effect lowers the Attic temperature by increasing the airflow in it.
