In pumping fluid with gas, pressure boost can be improved by enhancing the pump rotation speed, thereby improving the performance of the pump to a certain degree ; when the gas content is constant, by increasing the inlet pressure, the pressure boost can be enhanced and the pump efficiency be improved remarkably ; when the gas content is rather high, there will be a problem of matching between the gas pressure and the fluid pressure ; the performance of the multiphase pump can also be improved by means of rational design of buffer vessel and homogenizer
試驗分析認為,氣液混輸工況下,提高泵轉速可以提高增壓,在一定程度上能改善多相泵的工作性能;含氣率一定時,增加進口壓力,可使多相泵增壓值增大,泵效明顯增加,最大含氣率點后移,但含氣率很高時,存在氣液壓力相匹配問題;改進緩沖罐和均化器的設計,有利於氣液互相夾帶,避免氣囊產生,可改善多相泵的輸送性能。This overview highlights selected algorithmic solver code advances in the used simulation tools, the use and the modelling of new materials for crash energy absorption, concept car design techniques, massive parallel programming and performance gains, side impact barrier modelling, mechanical occupant surrogate modelling ( dummies ), biomechanical models of human parts, as well as extensions of crash simulation techniques to the simulation of drop tests for appliances, shock absorption of a mars lander, etc
