Thermal convection is often encountered by scientists and engineers while designing or analyzing flows involving exchange of energy. Fundamentals of Convective Heat Transfer is a unified text that captures the physical insight into convective heat transfer and thorough, analytical, and numerical treatments. It also focuses on the latest developments in the theory of convective energy and mass transport. Aimed at graduates, senior undergraduates, and engineers involved in research and development activities, the book provides new material on boiling, including nuances of physical processes. In all the derivations, step-by-step and systematic approaches have been followed.

CHAPTER 1

Preliminary Concepts and Basic Equations

1.1 REYNOLDS TRANSPORT THEOREM

The rate of change on N for a system equals the sum of change of N inside any arbitrary control volume in continuum and the rate of efflux of N across surface. This can be represented as

$\frac{DN}{Dt}=\frac{\partial }{\partial t}{\displaystyle {\iiint }_{\forall }\eta \left(\rho d\forall \right)}+{\displaystyle {\iint }_A\eta \left(\rho \mathbf{\text{V}}.dA\right)}$

(1.1)

N ≡ extensive property; η ≡ specific property; V ≡ velocity vector. We apply Eq. (1.1) for the purpose of mass conservation. The quantity M stands for mass of the system and the corresponding specific property is 1. The Reynolds transport theorem can be written as

$\frac{DM}{Dt}=\frac{\partial }{\partial t}{\displaystyle {\iiint }_{\forall }\rho d\forall }+{\displaystyle {\iint }_A\rho \mathbf{\text{V}}\cdot dA}$

(1.2)

${\displaystyle {\iiint }_{\forall }\frac{\partial \rho }{\partial t}d\forall }+{\displaystyle {\iiint }_{\forall }\nabla \cdot \left(\rho \mathbf{\text{V}}\right)d\forall }=0$

(1.3)

${\displaystyle {\iiint }_{\forall }\left[\frac{\partial \rho }{\partial t}+\nabla \cdot \left(\rho \mathbf{\text{V}}\right)\right]d\forall }=0$

(1.4)

$\frac{\partial \rho }{\partial t}+\nabla \cdot \left(\rho \mathbf{\text{V}}\right)=0$

(1.5)

$\frac{\partial \rho }{\partial t}+(\mathbf{\text{V}}\cdot \nabla ...$
