Theoretical Foundation on Conservation Equations of Laminar Mixed Convection
In this chapter, the basic conservation equations corresponding to laminar free and forced mixed convection are introduced. For this purpose, the related general laminar conservation equations on continuity, momentum and energy equations are presented by means of theoretical and mathematical derivation for deeply understanding fluid convection. From these general conservation equations of convection, the fluid’s variable physical properties are fully taken into account. By using the quantity grade analysis, the mass, momentum, and energy equations of laminar mixed convection boundary layer are obtained with consideration of variable physical properties .
