模拟试验

In order to illustrate the phenomena occurred in the technological experiments, the infiltration dynamics of liquid aluminum into porous media was simulated in accordance with the laws of similitude. The results show that (1) the relation between the displacement of infiltration front and the advancing time is 〓;(2) the pressure of infiltration changes with time according to 〓;(3) the distribution of pressure in the direction of infiltration length is P=a〓+b〓L.(4) the change of temperature or viscosity of molten aluminum affects infiltration velocity in fillers of diameter in the range of 1. 5～5. 5mm very little, but this velocity in fillers of diameter 0.5mm is reduced with the decrease of AL temperature.

为了说明工艺试验中显示的各种现象，作者根据相似原理，采用模拟试验研究了铝液在多孔介质中的渗流过程，得到铝液渗流动力学规律如下：（1）渗流前沿位移—渗流进行时间关系为〓；（2）渗流压强随渗流时间的变化规律为〓；（3）渗流压强沿渗流长度分布为P=a〓+b〓L；（4）铝液温度降低或粘度加大时，对大于1.5mm的颗粒之间的渗流速度影响不大，但使0.5mm颗粒之间渗流速度减小。

can be drawn by analyzing the experiment data:(1) With modeling indoor garbage column leaching test, the results indicated that the dynamic change of the pollution components of leachate display complex fluctuate attenuation; During the course of initial stages and middle stages, the garbage was decompounded quickly and gave out the quality concentration of pollutant maximally to the environments and the harm was also the most serious.
