Abstract: The process of molecular heat exchange of a motionless rather large solid spherical aerosol particle with the surrounding medium has been mathematically simulated at significant variations of the temperature in its vicinity. The obtained formulas make it possible to find directly the temperature distribution in the vicinity of the particle and the value of the molecular heat flow conducted from the particle surface taking into account the temperature jump and the temperature dependence of the thermal conductivity coefficient. The analysis of the theoretical results has shown that the increase in the surface temperature of the particle leads to a monotonic increase in the jump temperature of the gas near its surface. In the case of a rather large particle, this can lead to a strong decrease in the value of the molecular heat flow conducted from its surface.
