Free Convection Correlations

This lecture covers the fundamentals of free convection, where heat transfer occurs between a solid and a fluid in motion at different temperatures. It explains forced and natural convection, boiling, and condensation. The lecture delves into the governing equations for free convection, including mass conservation, momentum conservation, and energy conservation. It discusses the Grashof and Rayleigh numbers, laminar and turbulent flow conditions, and boundary conditions. The lecture also presents correlations for free convection on a vertical plate, focusing on laminar flow. It concludes with examples and calculations of the convection coefficient for free convection.
