Abstract:

The equations of motion for a conducting gas in the presence of a magnetic and an electric field are linearized under the assumption of small magnetic Reynolds number and nearly parallel flow by expanding the perturbation flow quantities in powers of the magnetic interaction parameter. In the first approximation the magnetic and electric fields act as body forces on the gas. The solution is obtained for the subsonic flow in a coaxial channel. A swirl type flow results if an electric potential is established between the two cylinders. By reducing the electric field and inner radius to zero, the solution for the subsonic flow in a tube is found. Graphs are presented for the perturbation velocity components and pressure in the tube induced by the magnetic field from a single current loop or a toroidal coil. The general solutions are given for the subsonic axially symmetric free jet and for both the subsonic and supersonic two dimensional free jet. The perturbation velocity components and jet shape are described for the magnetic field of a single current bearing wire. Author
