GAS FLOW TRACING IN BAFFLE-STABILIZED FLAMES,

Abstract

Three methods are discussed which permit detailed study of the recirculation zone of baffle-stabilized flames. The cold flow pattern bears no resemblance to the recirculation flow pattern in baffle-stabilized flames. The turbulence level within the recirculation zone of a baffle-stabilized flame is certainly an order of magnitude less than that of the cold flow. Assumption of instantaneous mixing in treating the recirculation zone appears not to be warranted in flames such as shown in the report. The direction of flow of the gases within the recirculation zone may be indicated by using a small tracer jet of propane. The magnitude of the recirculation velocity can be determined as a function of position throughout the recirculation zone by the jet penetration method described. (Author)
