Method of determination of thermal conduction coefficient and heat capacity of materials and the apparatus for measurements of thermal conduction coefficient and heat capacity of material

摘要: A method and apparatus for determination the thermal conduction coefficient heat capacity of materials. The comprises measurements flux across sample momentary temperature difference between both surfaces perpendicular to direction during continuous change one surfaces. values coefficient, diffusivity are determined on basis an equation which defines their dependence measured sample, rate surface. measuring conductivity contains a heater equipped with sensor thickness less than 1 mm, placed two samples, them being material tested 10 mm. samples in contact flowing gas or liquid stream constituting sinks samples. medium is changed linearly time each measurement run.
