Experimental study on effect of magnetic field on flow dynamics of iron (III) oxide (Fe2O3) - water based nanofluid using Taylor Couette flow apparatus

Experimental investigation of magnetic field effect on Fe3O4-Water based nanofluid undergoing Taylor Couette flow is great importance since some lubricating systems are replicas flow. In this study several experiments were carried out to investigate the influence nanoparticle concentration vortex dynamics a water Newtonian formulated from Fe2O3 in presence and absence field. Flow was studied relation transition, stability, hysteresis magnetism these properties. regimes covered include Circular flow, wavy Vortex Modulated Wavy Bifurcation parameters volume fraction, inner cylinder rotating frequency Reynolds number. Experiments performed distilled understand its behavior apparatus. Critical number, Azimuthal wavenumber travelling waves recorded for each fraction. Power Spectral Analysis using video data experiment. It observed that critical various transitions decrease with fraction but an inconsistent pattern These results show greatly
