Abstract

Abstract: A theoretical investigation is executed for exploring the flow, heat and mass transfer behavior of magnetohydrodynamic radiated ferrofluid flow caused by a cone in the existence of non-uniform heat source/sink. Dispersion of ferrous nanoparticles finds applications in heat exchanger system, recharge able batteries, chemical catalysts, metallurgy, conducting paints, magnetic recording media, drug delivery, nanofibers, textiles etc. in this study we have used the two types of temperatures namely water (At 10 °C and 50 °C), having less thermal conductivity as compared with magnetic nanoparticles (CoFe2 O4 ). A simulation is performed by mixing of cobalt ferrous particles in base fluid water with different temperatures. Also, we presented dual solutions for flow over a cone with CoFe2 O4 +water at 10 °C and CoFe2 O4 +water at 50 °C. Governing equations are solved using Runge-Kutta with shooting method and compared with published literature. From the formulated model we found that the friction factor coefficient and rate of heat transfer is more in mixture of CoFe2 O4 +water at 10 °C case compare to CoFe2 O4 +water at 50 °C case. Similarly the mass transfer rate is more in CoFe2 O4 +water at 50 °C when compared to CoFe2 O4 +water at 10 °C case. These results help us to conclude that depending on the industrial appliances we can use heating or cooling processes CoFe2 O4 +water at 10 °C and CoFe2 O4 +water at 10 °C fluids respectively.
