- Abstract
- A computational grid is a crucial component in computational fluid dynamics, that greatly affects the accuracy and the cost of a numerical analysis. However, generating a grid with high quality is challenging and time-consuming, for turbomachinery blades with various shapes and configurations. In addition, the user-dependency in grid generation deteriorates the reliability of the analysis. We develop an algorithm that can automatically generate a structured grid for simulations of flow over a turbomachinery blade. Using an elliptic grid generation method, a high-quality O-type grid with high grid orthogonality on the wall is generated. Users only need to specify basic grid specifications such as grid number and resolution. The efficacy of the developed algorithm is evaluated for various two-dimensional and three-dimensional blades.
