Motion of thermal center at unbalanced heating of flat body

Abstract

Using the analytical dependences the authors have developed the approximate method to calculate a space coordinate of thermal center motion at unbalanced heating of flat body with convective heat flows. In this case the thermal center at flat body heating with convective heat flows starts moving, the space coordinate corresponding to coordinate temperature derivative extremum turns out to be a certain time function. The type of space coordinate time dependence was determined. It is of great theoretical and practical importance. Using the proposed dependences it is possible to calculate the time moment when the flat body heating becomes one-side and it is converted into unsteady mode of heat transfer through the flat wall.
