Abstract: A comparative study has been made on thermal properties of magnetohydrodynamics (MHD) 3D ethylene glycol and water based colloidal suspension (Al, CuO and SiC) nanoparticles. Especially, fluid flow, heat and mass transfer characteristic for MHD three dimensional ethylene glycol based nanofluid is studied in the presence and absence of magnetic field. The involving nonlinear partial differential equations are reduced into ordinary differential equations by using similarity variables and then equations are solved numerically by Runge-Kutta method along with shooting technique. Nusselt number, Sherwood number and skin friction are calculated and their effect on the flow, heat and mass profiles are discussed graphically. It is interesting to observe that fluid velocity decreases with increase in Al-nanoparticles volume fraction whereas it increases for the nanoparticles CuO and SiC. Increase in the nanoparticles volume fraction increases the temperature both in presence and absence of magnetic parameter for all the three types of nanofluid under study.
Keywords: magnetohydrodynamics; MHD; nanofluid; shooting technique; Runge-Kutta method.
