Temperature Distributions of Radiant Gas Calculated by Monte Carlo Method

抄録

A new method is proposed in this paper for the calculation of temperature distributions of radiant gas which is bounded by two parallel surfaces and has a heat source. Some papers have been published on the calculating method in the case of gray gas with a uniform partial pressure and a uniform heat source. The author tried to calculate the temperature distribution in the case where the absorption coefficient of gas was affected by temperature. This method is also applicable to the case of nonuniform partial pressure and nonuniform heat source. The calculation was conducted by the Monte Carlo method and programmed for electronic digital computation. All examples in this paper were calculated by computer and an increasingly flattened temperature distribution was obtained for the gas in which the absorption coefficient was affected by temperature K (T_g)=KT_m/T_g as compared with that of the gray gas.
