External forced convection occurs when a fluid flows over a surface, driven by an external agent such as a fan or a pump. This type of convection is commonly encountered in various engineering applications, including heat exchangers, electronic cooling systems, and wind turbines. In Chapter 7 of Cengel's book, the author provides an in-depth analysis of external forced convection, covering topics such as the velocity and thermal boundary layers, laminar and turbulent flow, and the calculation of heat transfer coefficients.

To navigate Chapter 7 successfully, you must become comfortable with several dimensionless numbers and empirical equations. The chapter is structurally divided by geometry: 1. Drag and Heat Transfer in External Flow

Chapter 7 introduces as the ratio of actual heat transfer to the maximum possible heat transfer. NTU is a dimensionless measure of the exchanger size relative to fluid flow rates.

The ultimate goal of most convection problems is finding the convection heat transfer coefficient (
