Spray Evaporation in Recirculating Flow
Abstract
Since the overall rate of fuel evaporation in combustors is strongly influenced by the gas to drop relative velocity, detailed information on the aerodynamics of the flow in a given combustor configuration is essential for its prediction. Such aerodynamic information can be obtained either from measurements or mathematical simulation of events taking place in actual systems. Because of advances in mathematical modelling turbulent flow phenomena, and development of powerful techniques for solving the partial differential equations of fluid mechanics, the latter approach is becoming more efficient and economical. The flow equations can be solved using either 2-D or 3-D models; however, almost all practical systems may be treated as 2-D (axisymmetric) in the important region, which includes the region of soot formation near the fuel injector. The calculation procedures was here applied to the case of fuel injection into a recirculation zone behind a baffle in a duct.
