Abstract

This paper deals with the computational modeling of buoyancy-driven turbulent heat transfer involving spatially uniform volumetric heat sources in a semicircular geometry. The Launder & Sharma low-Reynolds number k-e turbulence model and the SIMPLER computational algorithm, which was incorporated into the CORE-TNC computer code, were used for the numerical modeling. The numerical model was subsequently benchmarked with experimental data from the hemispherical-shaped Mini-ACOPO test facility for the modified Rayleigh number range of 2x 1
