This chapter presents the equation of nonstationary heat transfer in a rod. Because of the original variable temperature distribution in the rod, heat flows from the hot regions of the rod into the cold, causing the temperature distribution to change not only along x but also with the time t...

A solution of the convection-conduction heat-transfer equation in porous media by the von Rosenberg finite-difference scheme von Rosenberg developed an explicit finite-difference scheme for solution of the linear convection-conduction partial differential equation in one space dimension. The method is sta...
The general steady one-dimensional conduction heat transfer equation with no generation is written as (5.9)1RNddR(RNkdTdR)=0 The general unsteady one-dimensional conduction heat transfer equation with source term is written as (5.10)1RNddR(RNkdTdR)+q‴=ρCp∂T∂t where R and N in bo...
THE ANALYSIS OF THE CONVECTIVE-CONDUCTIVE HEAT TRANSFER IN THE BUILDING CONSTRUCTIONS The numerical model for the analysis of the combined convective-conductive heat transfer in the building components has been developed. Presented model is based on the partial differential equation for the twodimensional...
1、Convection As mentioned earlier, there are three mechanisms of heat transfer: conduction, convection, and radiation. Conduction and convection are similar in that both mechanisms require material medium, but the difference is that convection requires the presence of fluid motion. And heat transfer ...
