Heat Transfer Modes: Conduction, Convection, and Radiationoffee and its environment is to identify the modes of heat transfer and the thermal channels of heat flow between two locations. There are different pathways, or thermal channels, that heat can take from hot coffee to ambient; directly from the coffee to the air above the free surface, through the s

1-Node Transient Modelseat transfer rates are driven by temperature differences, the first step in analyzing heat transfer problems is usually to solve for the temperature field, which depends on spatial position and time. Numerical analyses involve the discretization of space (breaking the physical region into discrete s

Multi-Node Transientse a simple extension of the principles developed for the few-node model. However, in programming a multi-node simulation, some or all of the recursion formulas can be written in terms of an input numerical parameter, say “n” and the governing equations are derived in terms of “n”. These problems can

Heat Transfer Fins (and Handles) (and handles). The approach is applied to the coffee/mug problem, this time with half a mug, and the heat transfer into the rim and out to ambient is detailed. Extended surfaces are widely used as either heat transfer fins (devices designed to increase the overall rate of heat transfer between a so

Convection Fundamentals of Newton’s “Law” of Cooling requires a closer look at the fluid in the immediate vicinity of a solid object at a different temperature. In this chapter, a 1-node analysis of the flow across a thin flat plate is developed that reveals the underlying physics of convection. The concept of a boundary

Internal Flows Models and the walls of the duct are at a different temperature. This chapter addresses internal flows in which a single ducted stream is involved. The next chapter considers heat exchangers, where one stream transfers heat to another. When mass flows into a control volume, it carries the energy associate

Heat Exchanger Fundamentalscused on the flow of a single stream that exchanges heat with its environment. This chapter considers the exchange of heat between two streams at different temperatures separated by a solid barrier. The aim is to develop a simplified modeling approach that can be used as a preliminary design tool. A
