Abstract
The addition of colours to flow visualization allows a third dimension to be added to the intrinsically two-dimensional information rendered by an image.In the present work, the velocity domain and the wall heat transfer in the near field of a jet in cross-flow is experimentally investigated by making extensive use of coloured images. Tests are performed in a low turbulence wind tunnel at a jet Reynolds number equal to 8000 and for velocity ratios ranging from 1 to 5. Data are obtained with Particle Image Velocimetry (PIV) and with infrared thermography applied to the steady state heated-thin-foil technique.
