Abstract: | The approximate analytical solution,with a basic tool of the heat balance integral method, to a class of one dimension heat conduction equation with phase change is found out under the condition that a steady heat source exists. Based on the observed data about permafrost and thaw lakes at Barrow in the Alaskan Arctic,the relation between the thaw depth of permafrost under a thaw lake and time for a period of 3000 years is obtained by using the obtained approximate analytical solution. |
