In the present paper, the study on the optimal horizontal air jet velocity of a range hood system has been studied by three dimensional numerical simulation. It has been shown that the air jet of a range flood system generates coanda effect confining the contaminated (high temperature) air in a certain region while the jet pushes out more contaminated air into a room as the jet velocity increases. Therefore, the optimal jet velocity has been determined by the combination of the two mechanism.
