Title Thermal Analysis in Hiemenz Flow of Viscous Fluid with Hybrid Nanoparticles

Author(s) Nadia Khurshid

Abstract As opposed to conventional nanofluids, hybrid nanofluids are regarded as more suited fluids in practical applications of heat transfer. Since the hybrid nanofluids' combined properties of two or more nanomaterials result in greater thermal conductivity of base liquid. The present study examines heat transfer in a Hiemenz flow over bi-directionally stretched sheets by comprising hybrid nanoparticles (SWCNT, MWCNT with base fluid water). Additionally, the heat transfer phenomenon is analyzed in the presence of magnetic field effect. The partial differential equations are subjected to the appropriate similarity transformations in order to create a dimensionless system of equations. A dimensionless system using the bvp4c approach (MATLAB-builtin function) is solved numerically and outcomes presented in graphical forms. Effects of the dimensionless physical parameters on flow and thermal profile is also discussed. By comparing basefluid, nanofluid (SWCNT and water), and hybrid nanofluid (SWCNT, MWCNT and water), the effects of dimensionless parameters on velocity and temperature are graphically abstracted. Physical explanation effectively support the study's findings.
