The results show that, comparing with the gas pressure drops calculated by the modified ergun equation, in the cases of the gas reynolds number is small, due to the presence of the dead space, the observed p in the experiments are bigger than that obtained by calculation, and when the gas reynolds number is large, because of the small interfacial viscous drag - force between gas and liquid, the p observed are smaller than that obtained by calculation
結果表明在氣相雷諾數較小時，由於停滯孔隙率的存在，實測壓降值比修正厄根方程計算的值大；氣相雷諾數較大時，氣液界面上產生的粘性曳力較小，實測壓降值比修正厄根方程計算的值小。 -
