Abstract : The purpose of this study was to design and fabricate a new geometry heat transfer shape for use in two-phase air-water spray flow. Upon completion it was found that overall film heat transfer coefficients were 60% larger than for two previous shapes, a circular and an elliptical cylinder. The new blunt body shape was reduced in size and a comparison of both sizes was made. Overall heat transfer coefficients were found to be 20% less. Also temperature differences from 0 to 60 degrees F were investigated and there was little effect on heat transfer coefficients in this range.
