Research Abstract

We have developed numerical analysis codes for the time-dependent two-and three-dimensional Navier-Stokes Equations together with the steady two-and three-dimensional Maxwell Equations with a turbulence model in order to realize a high performance MHD generator with CO2 recovery. The Navier-Stokes Equations are solved with the Harten-Yee upwind TVD method, which can capture strong shock waves and a parallel computation is used to reduce the computation time, whereas the Maxwell Equations are solved with the finite element method with linear tetrahedron elements.
Results obtained by the three-dimensional analyses showed that strong oblique shock waves were induced between the nozzle and insulator in the magnetic field direction, and the shock waves propagate downwards to the exit, resulting in a large influence on the MHD generator performance, which could not be obtained with the two-dimensional analyses. It was also revealed that the shock wave induced within MHD generators had a strong relation with the electric current distribution and a large boundary layer separation was induced, resulting in a large pressure loss when the MHD generator was operated with a high current density.
We also studied the interaction between the MHD generator and the AC power grid through inverter systems and found that the MHD generator could provide the electric power to the grid, and also preliminarily that introduction of forced commutated inverter systems could stabilize the AC grid by means of simultaneous control of the active and reactive power.
