In the article the numerical scheme of calculation of heat exchange of a dispersiblis material is offered on the basis of solution of a non-stationary problem of heat exchange within the framework of an elementary cell. The given approach allows to determine time of an establishment of homogeneous state of a sample, its effective heat conductivity, and also eliminates the certain reserve connected to a choice of isothermal surfaces in a traditional method. Features of the numerical decision of the given problem are considered: construction of the scheme of finite difference approximation, the amendments permitting to save conservatism of the scheme.
