Governing equations for transport phenomena

From Thermal-FluidsPedia

Transport phenomena, which represent transports of momentum, heat and mass, include fluid mechanics, heat and mass transfer. The discussions of governing equations in the links below can be applied to Fluid Mechanics, Heat and Mass Transfer, thermal-fluids aspects of Combustion, as well as Multiphase Systems.

• Basics

Lagrangian approach and Eulerian approach.

• Integral Formulation

Transformation formula, continuity, momentum, energy, entropy, and conservation of mass species equations.

• Differential Formulation

Continuity, momentum, energy, entropy, and conservation of mass species equations.

• Classifications of PDE and Boundary Conditions

Elliptic, parabolic and hyperbolic PDEs and classification of boundary conditions.

• Boundary Conditions at Interfaces

Conservation of mass, momentum, energy, and mass species; and supplementary conditions.

• Averaging Formulation

Overview, volume averaging, area averaging, and Boltzmann statistical averaging.
