Flow field computation for simplified high voltage gas circuit breaker model by upwind meshfree method

To effectively design high voltage (HV) circuit breakers, a meshfree method which was proposed by the authors is tested. The meshfree method is implemented to a simplified model for the HV circuit breaker and showed a robust behavior even in a severe boundary condition. A good shock capturing is shown in the computations and a delicate gas diffusion through a slit is also computed, which is usually difficult to catch. Vector splitting method is employed to exploit the merit of meshfree methods in the hyperbolic problems.
