ANALYSIS OF HEAT AND MASS TRANSFER RATES OF HYDROMAGNETIC TURBULENT FLUID FLOW OVER AN IMMERSED INFINITE HORIZONTAL CYLINDER WITH HALL CURRENT

Abstract

A mathematical model of hydromagnetic turbulent boundary layer fluid flow past a horizontal infinite cylinder with Hall current is considered. The cylinder is placed in cross flow with the fluid. The fluid flow is impulsively started and the flow problem is subsequently analysed. The flow is modeled using the momentum, energy and concentration conservation equations. The Reynolds stresses arising due to turbulence in the conservation equations are resolved using Prandtl mixing length hypothesis. The equations are then solved by a finite difference method. The effects of flow parameters on the primary velocity, secondary velocity, temperature and concentration profiles are investigated. It is found that velocity profiles increase with increase in Hall parameter and temperature and concentration profiles increase with increase in magnetic parameter.
