ABSTRACT

A simple and robust discretization of the Low Frequency Transonic Small Disturbance (LF-TSD) equation is presented, suitable for applications such as fluid-structure interaction (FSI). Choices in the derivation and discretization of the LF-TSD equation are justified and the performance of the scheme is demonstrated for a typical nonlinear FSI problem.
