dc.description.abstractThis work is devoted to the visualization and characterization of a twin jet flow when impinging vertically to a solid surface, which is of primary importance to the understanding of the phenomena relevant to V/STOL type of aircraft performance and stability when operating in ground vicinity, during short take-off and landing. The visualization of a distinctive fan-shaped flow that is formed in the collision zone (or fountain formation zone) is the major concern in this work. Variables analyzed in this work are the separation distance, height and diameter of the jets. It was found that the fountain flow involves complex flow structures, quite sensitive to small imbalances between the jets. It was also observed that significant changes in the flow pattern and properties in the fountain formation zone occur with according changes in the parameters studied.pt_PT
