Fanno & Rayleigh Flows — Lesson 2

Consider the combustion chamber of a gas turbine. The combustion of the fuel–air mixture adds a significant amount of heat to the flow, increasing the total temperature of the gas between the compressor and the turbine.

Now, let’s consider a long gas pipeline. In addition to the compressible effects in such flows, the friction along the pipe walls also affects the total pressure loss incurred by the flowing gas. An understanding of these frictional losses becomes important when estimating the overall pumping power needed to transport the gas.

In this lesson, we will learn how heat addition (or removal) and friction at the pipe wall affect one-dimensional compressible flows.
