Aspects of Determination of Convective Coefficients

The paper deals with selected aspects in the determination of convective coefficients and the formation of air convection models on solid surfaces. The goal is to assess the suitability of individual approaches for application in specific situations, considering that convective heat transfer coefficients have a significant impact on the resulting accuracy of the facilities/process design. Convection is a dynamic phenomenon, its exact physical description is complex, convection coefficients cannot be measured directly. Correct determination of convective coefficients is therefore very important in various areas where thermal energy is transmitted in this way. The paper gives an overview of selected aspects of various methods for determining convective heat transfer parameters.
