Abstract : This report covers activities during the first year under ONR contract N00014-81-K-0428. The project is a combined experimental and numerical investigation of heat transfer and fluid dynamic characteristics of a turbulent swirling flow in a pipe downstream of a sudden expansion. Local wall heat transfer measurements as well as detailed flowfield measurements utilizing laser-Doppler velocimetry (LDV) techniques are planned for the experiments. Numerical modeling efforts will focus on the development of a code which is efficient enough to be useful for design purposes, while accurately modeling the flow field.
