Three-dimensional flow and heat transfer development in MHD channels
Abstract
The development of the three-dimensional flow and temperature fields in an MHD channel is studied. The partial-differential equations for the three momenta, the enthalpy, and the electrical fields are solved by a finite-difference calculation procedure. The turbulence phenomenon is represented by a two-equation turbulence model, in which additional equations are solved for the kinetic-energy of turbulence and its dissipation rate. Calculations have been made for typical MHD channel conditions in the subsonic flow regime. Interesting secondary flow patterns have been observed to develop along the duct as the flow and electrical fields interact with each other. The detailed development of the three-dimensional flow, temperature, and electrical fields is presented.
