Description

Welcome to Fundamentals of Heat Transfer Part 2: Enhance Your Understanding of Convection and Convection Coefficients

In part 1 of our course on Fundamentals of Heat Transfer, we focused on heat transfer by conduction and briefly discussed convection as a possible boundary condition. In part 2, we delve deeper into convection and convection coefficients.

Our first objective is to develop an understanding of boundary layer phenomena and the features that control the convection coefficient. We will discuss the hydrodynamic boundary layer concept and the thermal boundary layer, which is the region of the fluid next to the surface in which energy exchange is occurring, and examine its influence on the convection coefficient.

We then address the problem of convection and introduce methods for estimating convection coefficients associated with forced convection in external and internal flows. We also consider free or natural convection and present methods for estimating convection coefficients for common geometries.

Throughout the course, we will explore how to estimate convection coefficients to perform analyses on thermal systems experiencing different types of flow and heat transfer situations. We will examine how the convection coefficient depends upon fluid properties, surface geometry, and flow conditions.

By the end of this course, you will have an enhanced understanding of convection and convection coefficients, enabling you to apply these concepts in real-world scenarios.

We wish you good luck in your learning journey. Enroll now to advance your knowledge of heat transfer!
