Efficiency investigations were made on the two-stage turbine from a Mark 25 aerial torpedo to determine the performance of the unit with five different turbine nozzles. The output of the turbine blades was computed by analyzing the windage and mechanical-friction losses of the unit. A method was developed for measuring the change in turbine clearances with changed operating conditions. The turbine was found to be most efficient with a cast nozzle having a sharp-edged inlet to the nine nozzle ports.
The 14 papers in the Fluid mechanics and heat transfer in sprays section have application to combustion sprays, spray cooling for fire fighting, cooling towers, and fuel atomization. The 22 papers in the Heat, mass and momentum transfer in environmental flows symposium are related to air pollution transport, air infiltration to building envelopes, climatic change, radionuclide transport, power plant stack plumes, flow through geologic repositories of radioactive wastes, and intake flow to cooling towers. There are 36 papers which discuss measurement techniques in multiphase flow. The symposium on Multiphase transport in porous media contains 14 papers related to enhanced recovery of petroleum, remedial action of soil and groundwater, and hydrogen storage as hydrides. Most papers have been processed separately for inclusion on the data base.
