Heat Transfer by a Multiple Array of Round Jets Impinging Perpendicular to a Concave Surface

Abstract : An experimental investigation was undertaken to study jet impingement cooling of a semi-cylindrical concave surface in a semi-enclosed environment. The investigation showed that it was possible to obtain a correlating formula for the various parameters involved. The effect of jet 'spent air' on heat transfer was also observed. The results are compared with those of Kercher and Tabakoff who carried out a similar investigation using a flat plate. (Author)
