Abstract

It is suggested to use the “action” (integral analogy of electrostatic field energy) to calculate the effective heat conductivity of elementary cell. The suggested approach is applied to the calculation of heat conductivity of disperse materials, the characteristic, necessary in design of heat performance of space vehicles. The maximum divergence of calculation results in the comparison with the numerical ones does not surpass 10%.

Keywords:

Heat conductivity; “action”; elementary cell; disperse environment; temperature field
