Magneto-hydrodynamic (MHD) code has been widely used in the field of high current pulse technology, astrophysics and so on. Especially in recent years, with the rapid development of high pulse technology and magnetically driven experiments such as Z-pinch, magnetically driven flyer plate and magnetically driven quasi-isentropic/shock compression, experimental researchers and designers pay more and more attention to the correctness and reliability of MHD code. The verification and validation of program is an important means to evaluate the correctness and reliability of MHD code.
Two dimensional magnetically driven simulation code (MDSC2) is a magneto-hydrodynamic program developed by Institute of Fluid Physics, CAEP. The MDSC2 code has been used in numerical simulation studies of solid liner implosion and magnetically driven flyer plate experiments. The talk will introduce the recent progress, the verification and validation of MDSC2 code.
The MDSC2 code is verified by comparison with artificial solutions, mesh convergence analysis and comparison with mature codes, and is also validated by experiments, such as magnetically driven one-sided flyer plate, magnetically driven two-sided flyer plates and magnetically driven solid liner. The numerical simulation shows that, the MDSC2 code not only correctly represents the MHD equations, but also can correctly simulate the magnetically driven experiments. The MDSC2 code will be helpful to the study of high current pulse technology, high energy density physics, high pressure equation of state，and weapon physics.
