Objectives
After successful attendance of this module, the students know the substantial phenomena occurring in multi-phase flows. Additionally they are able to model these phenomena by means of the fundamental equations of thermo-fluiddynamics and have developed corresponding problem-solving competences.
Description
Gas-Liquid Mixtures (Gas-Flüssigkeitsgemische) are of paramount importance for energy and process-technology, consider e.g., fuel sprays in Diesel engines or gas turbines, boiling of water in the steam generator of a power plant, or the distribution of air bubbles in aerated stirred reactors or bubble columns.
A selection of physically interesting as well as technically relevant phenomena is discussed in this course. While technical applications are introduced frequently in an exemplary manner, the underlying physical laws, i.e., the conservation laws of mass, momentum, and energy, form the main subject. It will be demonstrated that diverse phenomena can be explained and described quantitatively within this unified framework, which represents the core of Thermo-Fluid Dynamics. Special emphasis is placed on instabilities and heat addition in two-phase flows.
Example problems will be solved and discussed in the tutorials (Übungen) to deepen understanding of the phenomena presented in the lecture and hone problem-solving skills.
