Descriptions
Fundamentals of Heat Transfer Part 2, In Part 1 of our Fundamentals of Heat Transfer course, we focused on heat transfer by conduction and briefly discussed convection as a possible boundary condition. In Part 2, we will look at convection and convection coefficients in more detail. Our first goal 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 adjacent to the surface where energy exchange occurs, and examine their influence on the convection coefficient. We will then address the problem of convection and present methods for estimating the convection coefficients associated with forced convection in external and internal flows. We will also consider free or natural convection and present methods for estimating convection coefficients for common geometries. Throughout the course, we will explore how convection coefficients can be estimated to perform analyses on thermal systems that exhibit various types of flow and heat transfer situations. We will examine how the convection coefficient depends on the fluid properties, surface geometry, and flow conditions. By the end of this course, you will have an advanced understanding of convection and convection coefficients, allowing you to apply these concepts in real-world scenarios.
