利用气－固两相流动的“双相耦合”模型，视固相为具有稳定流体性质的“拟流体”，则气、固两相流场成为真实流体与拟流体两种组分迭置的混合场，考察了在固相为稀相条件下，不同粒子浓度对气流场的影响，并应用“单相耦合”模型，分别算出固粒运动轨迹，初步探明固相浓度对叶轮磨损规律的影响。
Using the “two-phase coupled” model of gas-solid two-phase flow and the solid phase as the “pseudo-fluid” with stable fluid properties, the gas-solid two-phase flow field becomes the real fluid and the pseudo-fluid Mixed field. The effects of different particle concentrations on the gas flow field were investigated under the condition of dilute solid phase. The “single-phase coupling” model was used to calculate the movement trajectories of the solid particles respectively. influences.
