摘要
在实验室条件下研究了超声的热效应对渗透率的影响。结果表明.超声热效应在提高多孔介质渗透率中的作用.在低温条件下比较显著.与振动效应相比不可忽视.随着温度升高.作用逐渐减弱.在高温条件下,起主要作用的是机械振动作用.热效应作用不明显。
The thermal effect of ultrasonic in increasing porous medium permeability was studied under laboratory conditions. The thermal effect of ultrasonic had an important place in comparison with mechanical vibration at a lower temperature. With the increase of temperature, the thermal effect became weaker, and could be ignored at a high temperature.
