Simulation-based engineering science has radically transformed the way research is done across most science and engineering disciplines and emerged as a powerful approach for tackling the major societal problems of our time related to human health, environmental sustainability, and renewable energy. Fluid mechanics problems that are frequently at the center of many of these challenges are often so complex that simulation-based research is the only viable approach for tackling them. Typical examples range from optimizing the hemodynamic performance of medical devices in patient-specific anatomies, to manipulating turbulence in natural waterways to enable physics-based stream restoration, to developing strategies for reducing the cost of energy and mitigating environmental impacts when harnessing wind and water energy resources. Accurate numerical simulation of such flows poses a formidable challenge to even the most advanced computational methods available today.
In this talk I will discuss the advances we have made in my group toward the development of a powerful computational framework for simulating such flows that integrates an immersed boundary approach with curvilinear grids, features accurate and robust fluid-structure interaction algorithms for rigid bodies and soft tissues, can handle two-phase flows and free surface effects, and is capable of carrying out coherent-structure-resolving simulations of turbulent flows in arbitrarily complex domains with dynamically evolving boundaries. The ability of the method to yield striking insights into the physics of a broad range of real-life problems will be demonstrated by discussing:
1) vortex formation in intracranial aneurysms;
2) the vortex dynamics of left ventricular filling;
3) the interaction of coherent vortices with mobile sediment beds in natural waterways;
and 4) the onset of wake meandering in axial flow turbines.
Future grand challenges and opportunities for simulation-based fluid mechanics research will also be discussed.
