Time Resolved Tomographic Particle Image Velocimetry and InfraRed thermography techniques are simultaneously applied to investigate the correlation between the passive heat and momentum transportation of a continuous jet impinging on a flat plate. A circular and a chevron nozzle exit are investigated at fixed Reynolds number and at fixed nozzle-to-plate distance. Mean and turbulent fluctuation distributions of temperature at impinging surface and of velocity close to the wall are presented. Measurements revealed low temperature and high velocity fluctuations located along the apices of the chevron nozzle.
