Introduction to Free Convection: Governing Equations

This lecture covers the fundamentals of free convection, including the heat transfer between a solid and a fluid in motion at different temperatures, the boundary layer equations for laminar flow, and the Grashof and Rayleigh numbers. It also delves into the conservation of mass, momentum, and energy in fluid dynamics, emphasizing the importance of temperature-driven fluid motion and the inclusion of advection in heat transfer.
