涡轮活塞发动机工作的数学模拟能大大地节省发动机制造和调整的时间和费用。采用这种先进的方法要求不断地完善放热特性的计算方法。 目前,一般由经验关系式给出放热特性。由发动机强化程度、工况以及它的结构特征所决定的一些系数包含在有名的冈恰尔、维别和普加切夫关系式中。因此,现有的这些系数的选择方法,在一些情况下,尤其是在需要模拟非名义工况时不能采用。为了用维别关系式模拟部分工况,可以采用参考文献中所推荐的
The mathematical simulation of turbo-piston engine operation can save significant time and expense on engine manufacturing and tuning. Adopting this advanced method requires continuous refinement of the calculation of the exothermic properties. At present, exothermic properties are generally given by empirical relationships. Some of the coefficients, which are determined by engine intensification, operating conditions and its structural features, are contained in the well-known Gangnthare, Viebel and Pugachev relations. Therefore, the existing methods for selecting these coefficients can not be applied in some cases, especially when it is necessary to simulate non-nominal conditions. In order to simulate some of the conditions using the relation of the dimension, can be used in the reference recommended
