METHOD TO DETERMINE TEMPERATURE CONDUCTIVITY OF SOLID BODY UNDER TRANSIENT THERMAL MODE

摘要

FIELD: measurement equipment.;SUBSTANCE: substance of the suggested method consists in heating of a solid body with the help of contactless thermal impact at front face surface of the latter with a source of infrared radiation. The temperature field of the solid body is recorded with the help of a system of thermal converters during the transient thermal mode determined by calculation. Using the experimental data, a one-dimensional transient temperature field of a solid body is built. Using the results of building of the temperature field of the solid body in the heating mode and differential equation of heat conductivity, the coefficient of temperature conductivity of the solid body is calculated.;EFFECT: higher accuracy of solid body temperature conductivity coefficient measurement under transient thermal mode.;6 dwg
