Convective and conductive heat transfer of creeping flow

While the conductive effect is small, its increase causes a slight decrease in the fraction of convective heat transfer coefficient from the total heat transfer coefficient, seen from Fig. 7b. When k f is smaller than k s as in Fig. 7 a, the fraction of heat transfer by convection increases steadily as φ is increased.

Heat transfer - Wikipedia

Heat is defined in physics as the transfer of thermal energy across a well-defined boundary around a thermodynamic system.The thermodynamic free energy is the amount of work that a thermodynamic system can perform.Enthalpy is a thermodynamic potential, designated by the letter "H", that is the sum of the internal energy of the system (U) plus the product of pressure (P) and volume (V).
