There are six transportive schemes corresponding to the computational stencils below.

1. Parabolic
2. Hyperbolic
3. Elliptic
4. Asymptotic parabolic
5. Asymptotic hyperbolic
6. Transverse isothermal

At this numerical grid resolution, the solution amplitude will decay exponentially with time.

Consider a 1d diffusion equation. The diffused profile is solved on a very coarse grid with a spatial step h for Courant=0.4 for the scheme from the Matlab activity. Consider a wavelength to grid spacing ratio, λ/h=3. What will happen at this numerical grid resolution with the solution amplitude as the time evolves?

An unsteady Navier-Stokes model of the jet problem is consistent and stable including the boundary conditions. This could mean that its solution's convergence to the experiment would be guaranteed when the grid is refined.

Computational fluid dynamics (CFD) is a field of study that applies mathematics and computer science to the analysis of fluid flow. It is used to understand and predict the flow of liquids, gases, and powders.CFD is used to design and test devices and systems used in industries such as petroleum, defense, manufacturing, and telecommunications.CFD is also used to study the behavior of biological tissues and biological fluids.
