Temperature estimation approach is examined for a heated jet in cross flow using velocity data by PIV and analytical results by CFD. A heated jet form transforms in crosswind since the buoyancy is caused by the difference of the density with fluid surrounding a heated jet. Centered streamline, velocity profile, and exit velocity of a heated jet at nozzle were experimentally measured by PIV, and this parameter is substituted for a numerical calculation as initial condition. The centered streamline obtained from PIV is compared with a numerical simulation by CFD, and the exit temperature at the nozzle is iteratedly replaced with the estimated exit temperature in order to converge with itself, and then the approach of which enables us to evaluate velocity and temperature fields of a heated jet by CFD.
