1017 Study on Heat and Fluid Flow in a Enclosed Rectangular Container Using LES and LIF

Abstract

The present study focuses on the turbulent natural convection heat transfer in a cubical enclosed rectangular container. The container is composed of the heated and the cooled side plates. The working fluid is water to attain larger value of Rayleigh number. The numerical simulation with LES is conducted at the same time in order to elucidate the experimental result with PIV and LIF methods. It is obvious that the heat transfer coefficient using simulation with LES is well correlated with that of the experimental investigation.
