本文就无粘平行混合计算最佳混合总压比,及其受函道比及能量转输效率的影响。 一、变比热内外函混合计算 在[1]提出的变比热气动函数式及几种解中,选用了k_k、k_v、k次准确解,误差在1％之内且略优于单k简化解,又避免了准确解的相对压力π~0及等熵指数(?)_v。焓值拟合公式取自[2],气体常数R值取自[3]。
In this paper, the optimal mixing total pressure ratio is calculated on the basis of non-stick parallel mixing, and its effect is influenced by channel ratio and energy transfer efficiency. First, the variable heat mixed with internal and external letter In [1] proposed variable heat aerodynamic function and several solutions, the choice of k_k, k_v, k exact solution, the error is within 1% and slightly better than the single k Simplify the solution, but also avoid the relative pressure π ~ 0 and the isentropic index (?) _v. The enthalpy value fitting formula is taken from [2] and the gas constant R value is taken from [3].
