| Summary: | In order to create a comfortable environment in the work place around commercial kitchen, it is desirable to accurately predict the capture efficiency of exhaust from the cooking appliance by CFD. Due to insufficient diffusion in buoyant plume, however capture efficiency tends to be overestimated in the k-ε model. In this study, we confirmed that the problem of the k−ε model in the prediction of plume is originated from the buoyancy production of the turbulent kinetic energy by comparing among the measurement value, simulated results using the LES model and the k−ε model, and possible remedy for discussed. |
