Validation Of Reynolds Averaged Model And Large Eddy Simulation In Actual Floor Heating Room

Hiroki Ono, Koji Sakai

Abstract: Today, computational fluid dynamics is often used to compute thermal environment of a target room. Thermal comfort, energy consumption and so on have been computed by a technique of CFD. However, heat transfer between wall and room air, which influences to the result of CFD much, is not validated enough in architectural conditions. This study focuses on that point at issue. We carried measurement to construct database to validate CFD, and benchmark test of RANS and LES turbulence models at steady-state. As a result, each model has enough accuracy to compute mean temperature. However, LES model shows superiority to RANS model in computing heat transfer.
