An Approximate Analysis of Laminar Magnetohydrodynamic Flow in the Entrance Region of a Flat Duct

摘要: Laminar flow of a conducting fluid with constant properties entering semi-infinite flat duct transverse applied magnetic field is considered. The assumed to enter the uniform velocity profile. walls are nonconducting and variable external resistance connects two end plates which displaced infinity. pressure distributions then determined for region between inlet fully developed flow. A method used wherein divided into sections an appropriate analysis utilized in each. In section near boundary- layer formulation equations solution series stream function Blasius functions as coefficients. When this becomes unwieldy, exponential deviation from joined boundary-layer complete description
