Workshop on research and development of JIEDI (JAXA Ion Engine Development Initiatives) tool for numerical evaluation of ion engine grid lifetime
抄録（英）
Improvements have been made to the grid erosion evaluation code (JIEDI-1) to achieve robust convergence and to enhance the accuracies of grid life estimations. The major improved features of the code are 1) the use of Newton-Raphson method and the ICCG solver, 2) modifications of the inlet boundary conditions, 3) incorporation of the differential sputtering yield and redeposition effect of the grid material, and 4) solution-adaptive mesh generation. The last feature is realized by the commercial mesh generation software "pro-STAR". Numerical code prediction of grid mass loss showed good agreement with that of mu10 ion engine life test, with robust convergence and improved simulation time by a factor of 3 - 4 in comparison with the previous code.
