Abstract
Mean velocity profiles and turbulence intensity were measured in turbulent plane air jet in a Push-Pull ventilation apparatus. Under the speed of jet is constant, we consider how mean velocity distribution and turbulence intensity distribution will change between jet nozzle and exhaust hood with experiment. Furthermore, we consider how plane air jet will be influenced by exhaust speed. When the influence caused by the exhaust speed is seen, (U_1/u^^-_m)^2 is decreased and the locus of the half-velocity points are increased.
