It takes into account the decomposition combustion mechanism of monopropellant, the principal effects due to high pressure, nonuniformity and unsteadiness of temperature distribution within the droplet, the liquid continuum equation, the strict requirements for mass, species, energy conservation conditions at liquid-gas...

A comprehensive theoretical model for unsteady evaporation/decomposition combustion of a monopropellant droplet in inert medium at high temperature and high pressure is developed. It takes into account the decomposition combustion mechanism of monopropellant, the principal effects due to high pressure, nonuniformity and unsteadiness of temperature distribution within the droplet, the liquid continuum equation, the strict requirements for mass, species, energy conservation conditions at liquid-gas boundary and the dependences of properties on physical parameters.The conservation equations of mass, species and energy are solved simultaneously by means of the complete implicit finite difference scheme. The effects of pressure on vaporization behaviours of an UDMH droplet in nitrogen gas at high temperature are calculated. The results show that the effects of pressure are very strong and the pressure limit for the supercritical evaporation/decomposition combustion of the UDMH droplet is about 5 MPa.

Based on the combustion mechanism of multicomponent droplets,theexistence of micro-explosion in diesel engine when water/oil emulsifiedfuel is used is experimentalpy tested and verified.Experiments have alsoconfirmed that the performance of diesel engine is independent of whetherthe state of emulsified fuel is oil-in-water or water-in-oil.Through the analysis of indicator diagrams,it,is found that the thermalefficiency of diesel engine using emulsified fuel is directly proportionalto the product of the degree of constant volume combustion η_(g1) and thecooling efficiency η_w,thus a method of optimization for the diesel perfor-mance is recommended.An example is introduced to show the final results.

从多成份液滴的燃烧机理出发,在柴油机中实验验证了燃烧乳化油时存在着微爆。实验也证明了柴油机性能与乳化油类型(油包水型或水包油型)无关。通过对示功图的分析,验证了柴油机使用乳化油时,热效率正比于燃烧定容度η_(?)和冷却效率η_(?)的乘积,由此提出了柴油机性能的优化方法,并以一个实例说明优化的效果。
