Abstract

This paper studied development of the three dimensional flow fields in a diagonal channel MHD generator. A diagonal insulating sidewalls type channel is proposed in this work. The partial-differential equations for the three momentum, the enthalpy and the electrical fields are solved by a finite-difference calculation procedure. The turbulence phenomenon is represented by two-equation turbulence model. Calculations have been made for typical MHD Diagonal channel conditions. The development of the three dimensional flow, current density and power generated is presented. At the end part we conduct a modification by diagonal angle of the channel. It is found that the power generated increase according to increment of diagonal angle.
