Marangoni mixed convection flow with Joule heating and nonlinear radiation

Abstract

Marangoni mixed convective flow of Casson fluid in a thermally stratified medium is addressed. Flow analysis has been carried out in presence of inclined magnetic field. Heat transfer analysis is discussed in the presence of viscous dissipation, Joule heating and nonlinear thermal radiation. The governing nonlinear partial differential equations are first converted into ordinary differential systems and then developed the convergent series solutions. Flow pattern with the influence of pertinent parameters namely the magnetic parameter, Casson fluid parameter, temperature ratio parameter, stratification parameter, Prandtl number, Eckert number and radiation parameter is investigated. Expression of local Nusselt number is computed and analyzed. It is found that the Nusselt number decreases by increasing magnetic parameter, temperature ratio parameter, angle of inclination and stratification parameter. Moreover the effect of buoyancy parameter on the velocity distribution is opposite in both the opposing and assisting flow phenomena. Thermal field and associated layer thickness are enhanced for larger radiation parameter.

Marangoni boundary layer flow and heat transfer of copper-water nanofluid over a porous medium disk

“…Jiao et al 33 presented the magnetohydrodynamic (MHD) thermosolutal Marangoni convection heat and mass transfer of power-law fluids driven by a power law temperature and a power law concentration. Hayat et al 34 considered Marangoni mixed convection flow with Joule heating and nonlinear radiation.…”

“…Motivated by the above mentioned works, [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] in this paper we have a study on Marangoni boundary layer flow and heat transfer of copper-water nanofluid over a porous medium disk. The temperature of the disk (the surface temperature of Cu-water nanofluid) is a quadratic function of the radius.…”

“…Thus second grade fluid has been dealt with the linearized form of thermal radiation. Homotopy analysis method [40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55] has been implemented for the development of convergent series solution for velocity, temperature and nanoparticle concentration. Graphical results for velocity, temperature and nanoparticle concentration are analyzed for various embedded parameters of interest.…”

“…Henceforth, in various flow fields, the importance of thermal radiation cannot be overlooked. Non-linear radiation and Joule heating in Marangoni mixed convection flow were demonstrated by Hayat et al [35]. The impact of exponential temperature on radiation effects and particle shape was examined by Lin et al by utilizing heat transfer of copper water-based nanofluid and Marangoni boundary layer flow [36].…”
