Magnetohydrodynamic laminar free convective flow across a horizontal cylinder with adiabatic surface

Abstract

'the present dissenation deats ~yith thc problem of two.dimensional swady Magnctohydrodynamic taminar frce convcctivc flow across a horizontal cylinder with adiabatic surfaec, The goycrning equatiolls are transformcd to non-lincar ordinary differential cquations by using the suitable substitution, Thcsc ~quations are then solved numerically using implicit finite diiference method known as Keller box scheme, The results are presented in temlS of local ,kin frktion, ,ur!:.ce tempelJtllre distribution. the velocity profile and temperature prufile. Effects of the physical quantities for fluid havinp. different Praneltl numbers hayc bcen studied for the ea.les of i,wthermal and adiabatic pan of the, surface. The dimensionless skin friction cn-eftLcient, the surface tcmperature distribution. the velocity distribution and the temperature profile o\'er the "vhote boundary !a"'Cf are shown graphically by using the softwarc TECH PLOT I,)r diffel'ent values (>f the magnetic Pill'ametel' kf Jnd the I'rJndtl number }'I", Conduction. cOllvcction and Joule heating dfects on l\1af',nctohydrndYLlamic lI"w 1'0'" a ,emcal IJat plate have also becn studied.
