Research Overview

The T*AFSM focuses on computational engineering analysis with advanced flow simulation and modeling methods developed by the team. The T*AFSM pioneered the development of space-time (ST) methods for computational analysis of fluid-structure interactions (FSI), fluid-object and fluid-particle interactions, free-surface flows, and two-fluid interfaces. The T*AFSM also pioneered the ST computational analysis of parachute FSI, and brought parachute analysis to a new era in sophistication of the methods developed and level of computational challenges overcome. The T*AFSM has also successfully extended the computational analysis scope of the ST methods to challenging problems in biomedical engineering and biomechanics, with emphasis on patient-specific cardiovascular fluid mechanics and FSI, cerebral aneurysms and stent treatment of cerebral aneurysms, coronary arteries, and heart valves. With new ideas based on the unique features of the ST computational framework, the T*AFSM brought new and powerful ways of analysis to flapping-wing aerodynamics, with emphasis on wing motion extracted from video recordings of an actual locust in wind tunnel, and wind-turbine aerodynamics, with emphasis on representing the actual rotor geometry and accounting for the rotor-tower interaction. The impact the T*AFSM made in computational analysis of different classes problems, the core ST methods the team developed and improved over the years, and the special ST methods it developed for each class of problems have been documented in the team's publications. The publications include over 210 ISI-indexed journal articles and a textbook on computational FSI.

Examples

The last update on these pages was based on a 2010 journal article -- 156th in the list of 212 ISI-indexed journal articles. These pages will gradually be updated based on the newer articles in that list. In the meantime, for a glance at some of the work published since the 156th article, see TAFSM Featured. For full description of the work published since the 156th article, see Journal Publications.
