Abstract:

EXPERIMENTAL INVESTIGATTIONS ARE PROPOSED ON FUEL ATOMIZATION AND AIR-FUEL INTERACTIONS IN A TURBULENT ENVIRONMENT. UNDER THE PROPOSED PROGRAM THE TWO BASIC AREAS OF RESEARCH WILL BE ADDRESSED; COLD FLOW SPRAY CHARACTERIZATIONS IN A TURBULENT FLOW FIELD WITH AND WITHOUTEVAPORATION AND DROP DRAG DETERMINATIONS WITHIN A POLYDISPERSION. DETAILED SPRAY DROP SIZE AND VELOCITY AND GASEOUS FLOW TURBULENCE MEASUREMENTS WILL BE MADE WITH THE RECENTLY DEVELOPED TWO-COMPONENT PHASE/DROPPLER PARTICLE ANALYZER, P/DPA. MEASUREMENTS OF THE DROP SIZE AND VELOCITYDISTRIBUTIONS AND TWO COMPONENTS OF MEAN VELOCITY, TURBULENCE INTENSITY AND REYNOLDS SHEAR STRESS FOR THE AIR FLOW WILL BE OBTAINED. BECAUSE OF THE IMPORTANCE OF THE DROPLET DRAG COEFFICIENT TOTHE COMPUTATIONAL EFFORTS, A SERIES OF EXPERIMENTS WILL BE CONDUCTED TO MEASURE THIS PARAMETER. THE EFFECTS OF DROP-DROP INTERACTIONS ON THE DRAG CONEFFICIENTS WILL ALSO BE CONSIDERED. DRAG DETERMINATIONS WILL BE MADE BY INJECTING NONODISPERSED AND POLYDISPERSED SPRAYS INTO AN UNIFORM CROSSFLOW AND MEASURING THE DROP SIZE AND VELOCITY AT A NUMBER OF DOWNSTREAM LOCATIONS.
