High-Order Accurate Partitioned Algorithms for Fluid-Structure Interactions and Conjugate-Heat Transfer

Fluid-structure interaction (FSI) problems are important in many areas of engineering and applied science such as modeling of blood flow, flow-induced vibrations of structures, and wave energy devices, and there is significant interest in numerical simulation tools for such problems.  Conjugate heat transfer (CHT) also plays an important role in many FSI simulations such as the cooling of turbine blades, heat exchangers, nuclear reactors, semiconductor devices, etc.  In this research project, we aim to build upon our recent work in this area to develop stable partitioned algorithms for new classes of FSI problems that also include CHT effects. The faculty and students working on this project will address the development of high-order accurate schemes for these FSI-CHT problems.  High-order schemes are especially useful for wave-dominated regimes such as high-Reynolds number turbulent flows and propagation of elastic waves.  At the same time, achieving high-order accurate interface coupling approaches for partitioned schemes presents numerous intellectual and numerical challenges.
