ABSTRACT
A mathematical model of hydromagnetic turbulent boundary layer fluid flow past a vertical infinite cylinder with Hall current is considered. The fluid flows along the axis of the cylinder. 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. The skin friction, rate of heat and mass transfer are computed and presented in tables. While the effect of Hall current on Primary velocity was not observed due to turbulence there was decreased secondary velocity profile when Hall parameter was increased.
