Numerical Simulation of Water base Magnetite nanoparticles between Two Parallel Disks

Abstract

Present study examines the fully developed squeezing flow of water functionalized magnetite 29 nanoparticles between two parallel disks. For strongly magnetite fluid three different types of nanoparti- 30 cles having better thermal conductivity: Magnetite (Fe3O4), Cobalt ferrite (CoFe2O4) and Mn–Zn ferrite 31 (Mn–ZnFe2O4) are incorporated within the base fluid (water). Systems of equations containing the 32 nanoparticle volume fraction are rehabilitating in the form of partial differential equations using cylindri- 33 cal coordinate system. Resulting mathematical model is rehabilitated in the form of ordinary differential 34 equationswith the help of compatible similarity transformation. Results are analyzed for velocity, temper- 35 ature, reduced skin friction and reduced Nusselt number with variation of different emerging parameters 36 and determine the superb thermal conductivity amongmentioned nanoparticles. Comparison among each 37 mixture of ferrofluid has been plotted as response to differences in reduced skin friction and reduced 38 Nusselt number distributions. Dominating effects are analyzed for squeezing parameter and it is found 39 that water based-magnetite (Fe3O4) gives the highest reduced skin friction and reduced Nusselt number 40 as compared to the rest of the mixtures. Isotherms are also plotted against various values of nanoparticle 41 volume fraction to analyze the temperature distribution within the whole domain of squeezing channel.
