Learning outcomes |
Make the student familiar with the effects of bubbles, droplets or solid particles on the flow of a liquid in nature and industrial processes. By the end of the course, the student should know how to classify various multiphase flows and know how to determine which mechanisms are at play for various conditions which occur in natural processes and industry.
