Flux dispersion method

The convective flux describes the transport of a quantity, such as momentum, heat, or mass, due to the bulk movement of a fluid. It is represented by a term in the governing equations that involves the fluid velocity and the property being transported. For example, in momentum transport, the convective momentum flux is given by ρvv, where ρ represents density and v represents velocity.

 The viscous flux arises from the internal friction within the fluid, which creates stresses that transfer both momentum and heat. It is represented by terms in the governing equations that involve derivatives of the velocity field and the fluid viscosity. In the Navier-Stokes equations, the viscous flux terms account for the effects of viscosity on momentum transport.

 You can visualize the velocity field and other properties, such as temperature or concentration. The simulations can demonstrate convective flow patterns and the impact of viscosity on the flow. Additionally, you can visualize the results, including velocity vectors, streamlines, and temperature or concentration profiles.
