Simulation of Rigid Body Motion for Engineering Analysis

Course Duration: 2 Days

Prerequisites

None

Who Should Attend

This course is intended for any engineer involved or interested in CFD modeling of applications involving rigid body motions. Prior experience with a CFD tool, preferably STAR-CCM+, is strongly recommended, but not required.

Course Description

The purpose of this course is to teach the techniques needed to conduct accurate and efficient analyses of flows involving rigid body motion using computational fluid dynamics. Examples of such applications include rotating machinery, floating vessel motions, fuel tank sloshing and flow control valves. The course is structured as a combination of lectures and workshops (tutorials). The first day of the course covers meshing for rigid body motion problems and the analysis of problems in which the motion is assumed to be known a priori. The workshops demonstrate available analysis techniques including the moving reference frames approach as well as transient sliding mesh analyses. The second day of the course focuses on the analysis of flows in which the motion of the rigid body is not known and is to be predicted. An introduction to such multi-DOF problems is followed by workshops which demonstrate the various available mesh motion options for several problems of engineering interest. The course concludes with an open session (time permitting) during which specific modeling issues of interest to the students can be addressed.
