DEVICE FOR MEASURING THERMAL CONDUCTIVITY OF POROUS BODIES FLUID-SATURATED UNDER PRESSURE

摘要

FIELD: instrument engineering.;SUBSTANCE: device for measuring thermal conductivity of porous bodies fluid-saturated under pore pressure of up to 100 MPa and temperatures of 200÷500 K, implementing the stationary method of a flat layer in which the heater and the refrigerator are constructive force elements of the measuring autoclave. The sample is placed between the heater and the refrigerator using liners of plastic material to provide thermal contact between them. The device also comprises a tube for vacuum pumping of the cavity with the sample. The walls of the cavity containing the sample are made preliminary polished.;EFFECT: improving the accuracy of measurement of thermal conductivity of fluid-saturated porous bodies.;3 cl, 1 dwg
