چکیده
Convective heat transfer due to laminar fluid flow past a flat plate is standard problem in transfer. While constant flux or temperature along the often assumed for solving such problems, there may be several practical scenarios where varies as function of both space and time. Developing an analytical solution resulting distribution important understanding optimizing thermal performance systems. some work exists on analyzing problems with time-dependent space-dependent flux, lack general This paper presents this by integral form energy equation, use fourth-order Karman-Pohlhausen polynomials velocity distributions momentum boundary layers. A non-linear, first order, hyperbolic partial differential equation derived response time- space-varying flux. shown agree well results from special cases. Numerical solutions generalized are presented. Based approach, predicted profiles that interest applications. Results improve our unsteady convective transfer, contribute towards modeling optimization engineering systems phenomena occur.

Fluid Flow and Heat Transfer of Nanofluids over a Flat Plate with Conjugate Heat Transfer
The falling and settling of solid particles in gases and liquids is a natural phenomenon happens in many industrial processes. This phenomenon has altered pure forced convection to a combination of heat conduction and heat convection in a flow over a plate. In this paper, the coupling of conduction (inside the plate) and forced convection of a non-homogeneous nanofluid flow (over a flat plate) ...

In this study, a similarity analysis is made for an unsteady two-dimensional MHD free convective and heat transfer flow of a viscous incompressible fluid along a vertical flat plate with internal heat generation/absorption. The governing time-dependent boundary-layer equations are reduced to non-linear ordinary differential equations by introducing a similarity transformation. The obtained simi...
