Predicting the temperature distribution in laminar two-phase flows is essential a wide range of engineering applications, like heat dissipation electronic equipment and thermal design biological reactors. Motivated by this, we extend classical Graetz problem, studying transfer between two flowing phases core-annular flow configuration. Using rigorous two-scale asymptotic analysis, derived coupled one-dimensional advection–diffusion heat-transfer equations (one for each phase) embedding effects advection, diffusion (both axial transverse) viscous dissipation. Specifically, mechanisms are described through effective velocity coefficients, while interaction accounted via ad hoc coupling source terms, respectively. The dynamics problem controlled seven dimensionless groups: Péclet Brinkman numbers, flux, viscosity, diffusivity conductivity ratios, volume fraction. Our analysis reveals existence main regimes, depending on disparity phases. When ratio order one, strongly coupled; otherwise, thermally decoupled. Interestingly, investigate evolution coefficient thin-film limit, shedding light most common assumptions underlying extensively used models context film flows. Finally, closed-form scaling laws Nusselt number clarifying impact topology dynamics. Since our model has been first principles, hope that it will improve understanding forced convection.
