INTRODUCTION
In Chapter 3, the concept of transport equation was introduced, starting from the
concepts of control volume and accumulation rate of a property inside this control
volume. Diffusive and advective fluxes were also defined to account for exchanges
between the control volume and its neighborhood, and the concept of evolution equation
was introduced by adding sources and sinks to the transport equation. A “model” is
