Calculation of heat distribution in rod with variable heat irradiation coefficient on its surface
The analytical methods used for researching heat exchange processes in ribbed surfaces are based on assumption, that heat exchange coefficient is constant. But in real conditions this coefficient is variable, because of changes in thermal field along the rib. The authors have proposed the mathematic...

| Summary: | The analytical methods used for researching heat exchange processes in ribbed surfaces are based on assumption, that heat exchange coefficient is constant. But in real conditions this coefficient is variable, because of changes in thermal field along the rib. The authors have proposed the mathematical method for calculating heat distribution along the rib with constant cross section for case, when heat transfer coefficient on rib surface depends on longitudinal coordinate. The solution obtained is based on special Airy function. When using the recommended theoretical method the authors eliminated the assumption, that heat transfer coefficient is constant on whole ribbed surface. |
