Regimes of Non-premixed Flame-vortex Interactions
Detailed studies of flame-vortex interactions are extremely valuable to improve our understanding of turbulent combustion regimes. Combined experimental and numerical studies have already been performed in the premixed case during previous investigations. Therefore, we decided to carry out a detailed experimental investigation on the regimes observed during interaction of a vortex ring and a no...
متن کاملSYNTHESIS OF ULTRA-FINE PARTICLES OF BAFE12O19 BY CO- PRECIPITATION ROUTE USING CHLORIDE/NITRATE PRECURSORS
Ultra-fine particles of barium hexaferrite have been synthesized by co-precipitation method using barium nitride and iron chloride precursors with a Fe/Ba molar ratio of 11. Co-precipitation was carried out at 25 and 80°C using NaOH as a precipitant. Effect of coprecipitation and annealing temperatures on the phase composition and morphology of the products have been investigated using XRD and ...
متن کاملULTRA FINE FERRITE FORMATION IN Si-Mn TRIP STEELS
Abstract: In the present investigation, the effects of thermomechanical processing parameters and the steel chemical composition on the ultra fine ferrite formation characteristics were studied. This was programmed relying on the capabilities of strain induced transformation (SIT) phenomenon and applying to different grades of Si-Mn TRIP (Transformation Induced Plasticity) steels. According...
متن کاملinvestigation of flame location effect on flame temperature in premixed counterflow combustion of particle-cloud
the premixed counterflow flames propagation in combustion of mixture which is a uniform mixture of fuel particles and air is analytically studied. this analysis framework is based on thermal-diffusion model with assumption that the lewis number is unit and the strain rate is constant. velocity profile is assumed as a function of one variable like x. the structure of the flame is presumed to con...
متن کاملCover illustration: Non-premixed hydrocarbon flame
This year’s cover illustration, reproduced here as figure 1, depicts an image formed by a short-time (1/1000 s) exposure of a non-premixed hydrocarbon flame. The flow is driven by the buoyancy forces generated by the density difference from the combustion heat release and resulting temperature rise. The Reynolds number for this buoyancy-induced, turbulent flow is relatively low, estimated at a ...
