Nieh, S

The VC concept refinement has been concluded upon further studies on the fuel ignition and flame stabilization. The inclusion of the large-velocity-difference provision for fuel ignition and the cup-shaped flame stabilizer adds merits to the vortexing combustor. Two cold test models, i.e. a 10 in. ID benchscale model and a 4-1/4 in. ID exploratory model were designed, fabricated, and assembled. Considerations on flow field similarity, test flexibility as well as measurement systems were made. Significant progress has been made on the mathematical modeling of VC processes. A computer code of two-dimensional elliptic swirling turbulence gas-particle flows for VC geometry has been developed and debugged, and preliminary results have been attained. 3 refs., 10 figs., 2 tabs.
