Thermohydraulic simulation on CIC conductor with adaptive meshfinite volume method for KSTAR tokamak superconducting magnet

摘要

To study the quench in the CICC, the numerical analysis code was developed. The fully implicit time integration of upwind scheme for finite volume method is utilized to discretize the equations on the staggered mesh. The scheme of adaptive mesh is proposed for the moving boundary problem and the time term is discretized by the θ-implicit scheme. The discretized equations are solved by the IMSL. The error analysis of this method is performed by various step-sizes of time and space. The thermal hydraulic behavior of the CICC used in KSTAR is studied
