• HALL EFFECT ON THERMAL INSTABILITY OF COMPRESSIBLE COUPLE-STRESS FLUID IN PRESENCE OF SUSPENDED PARTICLES

Abstract

Effect of Hall current on the the thermal instability of a compressible couple stress fluid with suspended particles is considered in this paper. It has been found that suspended particles have destabilizing effect on compressed couple stress fluid. Also dispersion relations including the effect of Hall Current and compressibility on the thermal instability of couple stress fluid in the presence of suspended particles are analyzed. Stability of the system and oscillatory modes are considered and it is found that due to the presence of magnetic field and suspended particles oscillatory modes are produced which were non–existent in their absence.
