As the importance of the indoor environment increases. As part of a study to improve range hood performance, a flow analysis of chamber casing was conducted. flow analysis was performed by applying Realizable (  ) Model. For flow analysis, “STAR-CCM+” program of “SIEMENS” was used. It was analyzed how changes in inlet velocity, outlet velocity(flow rate) and static pressure increase occur according to changes in the shape of the chamber casing. Flow analysis was performed by changing the shape of the chamber casing limitedly, but the results were not helpful in improving the performance of range hood.
