摘要
用传递函数法求出不同流速、不同装填条件下的固定床流体轴向扩散系数D_(ax),并采用Lax-Wendroff差分格式对固定床对流扩散偏微分方程进行了数值解,比较了轴向扩散系数对固定床流出曲线的影响。
Based on two hypotheses, a formula for predicting the gas solubility in liquid, which is correlated with temperature and pressure, is proposed, and the solubility of nitrogen, hydrogen, helium and ethylene in water are predicted,the results obtained,even at low pressure,are satisfactory.
