The diffusion behavior of a horizontal buoyant jet discharged from a multiple pipe was investigated both experimentaly and numerically. Velocity and temperature of the jet were measured with FLV, thermocouples and propeller velocimeters, changing the number of pipe and the height of an outlet and the distance between the pipes. In each cases, a three-dimensional turbulence closure model (k-εmodel) was applied to simulate the behavior of the jets. The performance of the three-dimensional model was evaluated by the comparison of the numerical results with the experimental measurements.
