Numerical Simulation Analysis Mathematics of Fluid Mechanics for Semiconductor Circuit Breaker

Abstract: The paper derives the current-voltage relationship in the semiconductor circuit breaker based on the equation of fluid mechanics which has application for safe and water access. Then, the paper proposes a Newton iterative method based on the finite element analysis method to solve the nonlinear algebraic equation relationship in the semiconductor circuit breaker. At the same time, the paper constructed a coupled numerical model based on the hydrodynamic equations and applied it to the pulse current prediction.… Show more

“…From this, the amount of memory and calculation required for LU decomposition is calculated, and the memory required to save non-zero elements after LU decomposition is ensured, and the position of non-zero elements is recorded. In order to perform symbolic decomposition efficiently, the concept of column elimination tree is used to classify the problem as a path exploration problem of efficient graphs, thus making high-speed computation possible [11]. The actual LU factorization is performed with the amount of memory guaranteed during symbolic factorization.…”
