We developed the indirect measurement system of temperature field of a heated jet in cross flow by using PIV velocity data and CFD. The buoyancy is caused by the difference of the density with a surrounding fluid in a heated jet. Therefore, the change occurs in the jet form when the crosswind is received. Spread angle, velocity profile, nozzle exit velocity of a heated jet were experimentally measured by PIV, and this parameter is substituted for a numerical calculation as an initial condition. The streamlines obtained from PIV are compared with numerical simulation, and the initial condition is updated until convergence with a certain allowance. After that we can evaluate velocity and temperature fields of the flow.
