Abstract

The fluid---solid interface-tracking/interface-capturing technique (FSITICT) with arbitrary Lagrangian---Eulerian interface-tracking and Eulerian interface-capturing is applied to computations of fluid---structure interaction problems with flapping and contact. The two-dimensional model with contacting flaps is intended to represent a valve problem from biomechanics. The FSITICT is complemented with local mesh adaptivity, which significantly increases the performance of the interface-capturing component of the method. The test computations presented demonstrate how our approach works.
