摘 要: 根據(jù)相似原理，采用模擬試驗(yàn)的方法研究了與鋁液相似的模擬液在負(fù)壓作用下的滲流動(dòng)力學(xué)規(guī)律。實(shí)驗(yàn)得到控制鋁液滲流過程的相似準(zhǔn)則為：對直徑1.5～3.5mm的顆粒介質(zhì)為Froud e準(zhǔn)則，對直徑0.5mm的顆粒介質(zhì)為Reynolds準(zhǔn)則。在相似準(zhǔn)則指導(dǎo)下，原型鋁液和模型中模擬液的滲流過程是相似的。

Abstract:The infiltration dynamics of simulant liquid under negative pressure was studied by simulation test in accordance with the laws of similitude. It showed that the criterion of similarity which controls the infiltration of fluids is Reynolds criterion for fillers of diameter 0.5 mm, Froude criterion for fillers of diameter 1.5～3.5 mm. On the basis of similarity criterion, the infiltration process of molten aluminum in the prototype is similar to that of simulant liquid in the model.
Key words: negative pressure infiltration; laws of similarity; simulation test; molten aluminum
