Heat Transfer - Chapter 7 - External Convection - Convection over a Flat Plate with Laminar Flow

In this video lecture, we begin discussing external convection. We discuss a general process for determining the Nusselt number (Nu), which is a dimensionless convective heat transfer coefficient (h). For laminar flow over a flat plate, an analytical solution can be obtained. This requires solving the energy balance, momentum balance, and continuity equation simultaneously via a similarity solution. From this solution, the boundary layer thickness (both velocity and thermal) as well as the Nusselt number can be obtained.
