This book covers the transport of momentum, heat, and mass in non-equilibrium systems. It derives differential balance equations for general properties and introduces the concepts of convective and diffusive flux. These are applied to the conservation of mass. Next, differential force balances are used to develop the governing equations for momentum transport, and includes a discussion of stress and viscosity. Dimensional analysis is discussed. The differential energy balance is then presented, along with Fourier's law. Finally, differential species balances are performed for multicomponent systems, and Maxwell-Stefan diffusion and Fick's law are discussed. An analysis of turbulence and the statistical modeling of its effects on transport is provided. This is followed by a description of boundary layer theory, and then a discussion of the analogies between the transport of momentum, heat, and mass. Finally the two resistance model for interphase mass transfer is presented.
