| Outline of Final Research Achievements |
We applied a numerical method based on hyperbolic Navier-Stokes equations to computational fluid dynamics (CFD) on aircraft. We extended the method for three-dimensional problems and implemented it with an unstructured-grid flow solver FaSTAR. The original Navier-Stokes equations are five equations, whereas the hyperbolic equations are 20 equations since the equations of derivative values are added. When we solve the equations with an implicit time-evolution method, we need to solve the 20×20 matrix problems. In this research, we proposed an approximation method of the matrix. We showed that the approximation method can reduce the computational time remarkably and it is faster than the conventional CFD method.
