Multiple jets are often used to obtain high heat transfer in wide area. Heat and flow behaviour of multiple jets show more complicate characteristics due to the existence of the interactions between adjoining jets, and between jets and spent flows. To clarify the influence of the flow behavior on heat transfer fields, the time and spatial heat transfer coefficients over the impingement plate were measured using an infrared radiometer when four jets impinged to the impingement plate for various jets arrangement and separating distance from jet exit to the impingment plate. The flow fields were also visualized by means of a water table. The heat transfer characteristics is made clear from the results of the instantaneous heat transfer contour or temperature fluctuation values.
