Abstract

We evaluate the hyperbolic equations for one and two dimensional advection-diffusion equations.

Goal

We improve the convergence of high Reynolds number flow by using the hyperbolic equations proposed recently.

Objective

We evaluate the hyperbolic equations for one and two dimensional advection-diffusion equations.

N/A

Use of the Supercomputer

We develop a code of hyperbolic equation and evaluate the method.

Necessity of the Supercomputer

We need a supercomputer for three dimensional flow analysis.

Achievements of the Year

Figure 1 shows a result of one dimensional boundary layer problem. We obtain an accurate result with the hyperbolic method. Figure 2 shows number of iteration for convergence. The number of iteration is small for the hyperbolic method and increases with first order slope. We found that the hyperbolic method is very efficient.
