This study reports experimental evidence of gas phase micro-convection induced by support fibers used in droplet combustion experimentation. Soot aggregates formed during combustion of n-octane and n-decane droplets (initial diameters ranging from 0.5 mm to 5 mm) provide natural seeds to reveal the thermal and flow asymmetries involved. The experiments are carried out in an environment that red...

Hybrid Electric Vehicles HIGHLIGHTS PROCESS AND TECHNOLOGY STATUS – A hybrid electrical vehicle (HEV) is a vehicle equipped with either an internal combustion engine (ICE) and an electrical motor powered by electrical batteries. In 1997, Toyota sold in Japan the first modern hybrid electric car, the Toyota Prius. Today’s HEVs are an emerging technology in the automotive market, with manufacture...

the dual fuel engines at part loads inevitably suffer from lower thermal efficiency and higher carbon monoxide and unburned fuel emission. this work is carried out to investigate combustion characteristics of a dual fuel (dieselgas) engine at part loads, using a single zone combustion model with detailed chemical kinetics for combustion of natural gas fuel. the authors developed software in whi...

CFD analysis on the MSW incinerator combustion chamber provides crucial insight on the thermal flow fields, but a difficulty arise from the boundary conditions on the waste bed in which the combustion is governed by complicated heat and mass transfer phenomena. Solid waste bed combustion models are constructed to predict the combustion process and corresponding generation of gas phase species b...

nanocrystalline complex oxides have been synthesized by combination of sol–gel auto combustion and ultrasonic irradiation techniques using copper nitrate, zinc nitrate as metallic nitrates and glycine, urea and thiourea as fuels. sol-gel combustion (combination of the chemical sol–gel process and the combustion process) as a proper synthesized technique is used to synthesize zno/cuo nanocomposi...

The paper describes correlation between combustion knock intensity and combustion rate calculated as the heat release rate from combustion pressure traces of a hydrogen fuelled spark ignited engine. Unlike a gasoline spark ignited (SI) engine, the hydrogen fuelled engine can easily generate knock during combustion at working conditions similar to a gasoline engine. However, the hydrogen knock d...

• The flow field is found to vary greatly downstream of the perforated plate. conjugate heat transfer affects NO formation by relocating flame. preferential diffusion intensified due two-dimensionality flow. coupling effect these factors above determines generation rate. present work examines x emission characteristics a premixed micro-combustion system with plate implemented. For this, three-d...
