[CFD] The Energy Equation for Solids and Fluids in CFD

Описание: An introduction to the differential form of the energy conservation equation for fluid flows in CFD. The presented equation is valid for both incompressible and compressible flows, as well as stationary and moving solid regions and hence can be used in conjugate heat transfer applications. The following topics are covered:

1) 2:11 What form of the differential energy equation is valid for solids and which form is valid for fluids?

2) 4:31 What is the thermal/internal energy equation?

3) 9:18 Why do we need to consider the total energy equation?

4) 21:41 What about enthalpy?
