Frontiers in Computational Fluid-Structure Interaction and Flow Simulation: Research from Lead Investigators under Forty – 2023

Introduction

The Team for Advanced Flow Simulation and Modeling (T*AFSM) focuses on computational engineering analysis with advanced flow simulation and modeling methods developed by the team. The T*AFSM has members at Rice University in Houston and Waseda University in Tokyo. The T*AFSM members have been recognized internationally for advanced research with immediate relevance -- research that brings solution and analysis to real-world problems and makes impact on our lives. This recognition is evident not only in articles published and invited lectures given by the T*AFSM members, but also in numerous cover pages and magazine articles featuring T*AFSM work, as well as several prestigious awards.

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:

The graduate students in the T*AFSM learn the state-of-the-art computational fluid mechanics and FSI methods in one of the most accomplished groups in the world, from those who developed these methods. They gain skills in advanced scientific computing and visualization while gaining experience in computational analysis of some of the most complex and challenging engineering problems. They build a strong record of ISI-indexed journal papers, which is a measure of true impact and accomplishment in research and also a sign of good motivation, good skills, good work ethic, and strong determination. The graduate students in the T*AFSM at Rice University coauthored 42 ISI-indexed journal articles since 2007.
