A contact method of determination of thermophysical properties of rocks from core samples

  • 15 Accesses

Abstract

The zone of the action of thermal disturbances around a circular heat source on the surface of a semi-infinite body is estimated with the aim of using contact methods of determination of thermophysical properties of materials from core samples.
