The Lecture

The lecture provides an introduction to fluid energy machines in the context of fluid power and fluid work systems as well as energy assessment based on the efficiency. Different physical effects for energy conversion are considered. The focus of the lecture is on turbomachinery and positive displacement machines, the two most relevant subgroups of fluid energy machines. For these machines, the focus is especially on understanding between ideal and real behavior, characterization by means of dimensionless numbers, and scaling of machine behavior at different operating conditions.
