This study regards distributions of flow in the ventilation system used in the kitchen hood in a ship. In this study, for describing the flow in the ventilation system, three-dimensional steady-state turbulence was assumed for the governing equation. When the plume was formed, three gases, CO, CO2, and HCL, in the flow field of the hood were considered as the plume, and it was assumed that the sum of concentrations of the gases was 100%. As a result, it could be confirmed that the plume was smoothly discharged when the flow rate of the supply was ten times lower than that of the exhaust.
