【摘要】 建立了基于两相流音速的气固两相流激波模型,并进行了计算分析。与基于单相流音速的激波模型的计算结果比较发现,当气相体积比较大时,两种模型所计算的音速差别较小,激波的结果是吻合的;当气相体积比较小时,两相音速模型所计算的音速值与实际值更接近,其激波结果更合理。因此本文基于两相流音速模型的激波分析更具通用性。更多还原

【Abstract】 On the basis of a two-phase flow sonic velocity a gas-solid two-phase flow shock-wave model was set up,and calculations and analyses were performed.When compared with the calculation results of a shock wave model based on a single-phase flow sonic velocity it has been found that in the case of a relatively large gasphase volume the sonic velocity difference as calculated by using the above two kinds of models is relatively small and the shock wave results for the two models are in good agreement.When the gas phase volume is relatively small,the sonic velocity value calculated through the use of the two-phase sonic velocity model is in better correspondence with the actual value,resulting in more rational shock wave results.In view of the above,the shock wave analysis based on the two-phase flow sonic velocity model is more suited for general applications.更多还原
