Temperature dependency on mixed convection boundary layer flow over an isoflux horizontal circular cylinder (Kebersandaran suhu terhadap aliran lapisan sempadan bagi olakan campuran ke atas Silinder Bulat Mengufuk Isofluks)

Steady laminar mixed convection boundary layer flow past a horizontal circular cylinder with constant wall heat flux, immersed in a viscous and incompressible fluid of temperature-dependent viscosity is considered in this study. The governing partial differential equations were transformed using non...
