Calculation of the heat flux from a spherical particle in a molecular gas

The problem of calculating the heat flux from a uniformly heated spherical particle in a molecular gas is considered. The results of numerical calculations performed within the framework of the Hanson-Morse model using the linearized Wang Chang-Uhlenbeck equation are presented, which are obtained under the condition of purely diffuse reflection of gas molecules from the particle surface. The values of the temperature jump coefficient for particular gases have been determined.
