摘要

A turbulent natural convection flow (Ra = 1.58×10~9) in a confined cavity with two differentially heated side walls was nu- merically investigated by means of large eddy simulation (LFS). The mean flow in the cavity is characterized by stable thermal stratification and a relatively low turbulence level. The LES results for the mean flow quantities show good agreement with the experiment. This is particularly the case when the dynamic model is used.
