Özet

Hydromagnetic flow between two porous disks rotating with same angular velocity Ω about two non- coincident axes has been studied in the presence of a uniform transverse magnetic field. An exact solution of the governing equations has been obtained in a closed form. It is found that the primary velocity f/Ωl increases and the secondary velocity g/Ωl decreases with increase in either Reynolds number Re or the Hartman number M. It is also found that the torque at the disk η = 0 increases with increase in either M 2 or K 2. On the other hand there is no torque at the disk η = 1 for large M 2 and K 2. The heat transfer characteristic has also been studied on taking viscous and Joule dissipation into account. It is seen that the temperature increases with increase in either M 2 or K 2. It is found that the rate of heat transfer at the disk η = 0 increases with increase in either M or K. On the other hand the rate of heat transfer at the disk η = 1 increases with increase in K but decreases with increase in M.
