Abstract
In compliance with the previous investigations as stated by Ghosh [1-7], the authors have extended the problem which deals with the generalization of the MHD convective flow in a rotating frame of reference under the influence of an inclined magnetic field. This problem emphasized the theory of a MHD convective flow being dependent on five pertinent flow parameters, namely, Ha² (the Hartmann number), K² (the rotation parameter, which is the reciprocal of the Ekman number), m (the Hall current parameter), G (the Grashof number) and θ (the angle of magnetic field inclination with positive direction of the axis of rotation). This investigation adds to the MHD theory of a rotating fluid thus representing a study of the physical situation relevance in concurrence with geophysics and fluid engineering.
