A numerical study of laminar magnetohydrodynamic free jets

A finite-difference solution of the boundary layer equations describing the flow of a jet of a conducting fluid in a transverse magnetic field is presented. Both two-dimensional and axisymmetric jets are analyzed with rectangular and parabolic initial velocity profiles. Increasing the Hartmann Number the jet length becomes shorter, and the spreading increases with a resulting increase in transverse velocity and reduction of entrainment. The …
