We study theoretically magnetohydrodynamic (MHD) motion of a binary electrolyte in a concentric annulus subjected to a uniform, axial magnetic field. The annulus’ cylindrical surfaces serve as electrodes. When a potential difference is imposed across the cylindrical electrodes, radial electric current flows in the solution and interacts with the axial magnetic field to induce a Lorentz body for...

Helical coil heat exchangers are widely used in industrial applications ranging fromcryogenic processes, air-conditioning, and nuclear reactors to waste heat recovery due totheir compact size and high heat transfer coefficient. In this kind of heat exchangers, flowand heat transfer are complicated. This paper reports a numerical investigation of theinfluence of different parameters such as coil...

The title Dean of Agriculture in our land-grant system has been given to many great men. Some have had the opportunity and innate ability to create. One such leader was Dean Charles F. Curtiss of Iowa State College ( ISO. Among his many other monumental contributions, the most important was described by C. L. Burlingham, a student, at the dinner held at the Saddle and Sirloin Club in 1925 when ...
