RESD—2D二维燃烧模拟程序参数灵敏性计算研究

Studying of the Parameters' Sensitivity of RESD-2D Program

本文作者在一个模拟直喷式柴油机燃烧过程的二维模型的基础上，开发了可在微机上运行的二维计算程序，程序名为RESD—2D．本文应用该程序针对12150L柴油机进行了计算与研究，计算结果与其他文献所提供的实验结果相吻合；随后，对该模拟程序中与燃油喷射、混合、燃烧相关的参数以及计算参数的灵敏性进行了深入的研究，所得到的结论对于RESD—2D程序走向实用化具有指导意义．

On the basis of a two-dimensional model,which applied for simulating and analysising the combustion processes of DI diesel engines, a PC FORTRAN program called RESD - 2D is written, which can be used on personal computers. And the model is applied to study the 12150L DI diesel engine,the computed results are in good agreement with the experiment results. Subsepuently,the sensitivity of the code to a number of parameters related to fuel injection, mixing, combustion and computational parameters is studied. And the important conclusions are achieved, which are valuable to make this code to be practical.
