Abstract:

The use of liquid metal combustion as a Rankine cycle heat source in stored chemical energy propulsion systems for undersea vehicles has fostered interest in the fundamental processes occurring during such combustion. This paper reports an investigation into the use of high energy, real-time radiography to provide X ray images of the confined combustion of an oxidant injected and submerged in a fuel bath. Studies of the combustion processes and fluid dynamics of the jet driven circulating flow in the fuel bath are described. Results of tests using cylindrical combustors which have single, horizontal oxidizer jets at their centerlines are presented. Selected radiographic images showing some of the large scale, low frequency turbulence, dense product behavior and reaction zone growth which occurs during such closed combustion processes are presented and discussed. Keywords Rankine cycle, Liquids metal combustion, Cylindrical combustors, Fuel bath.
