Abstract:

The long-term objective is to critically evaluate the merits and limitations of plume modelling techniques. Preparations for the experimental investigation and computer program developments have been carried out. The design and construction of a facility for superheated Freon of high pressure to be used for jet plume simulation have been accomplished. Shake-down testing of the facility has started. A strut supported axi-symmetric model, extensively used in previous plume-afterbody flow investigations, has been modified for tests with heated Freon. Two propulsion nozzles for calibration tests and three nozzles for modelling tests have been constructed. This has been done in cooperation with the University of Illinois, where the internal flow characteristics for one of the nozzles have also been measured and found to be in excellent agreement with the computed predictions.
