This portal has been developed to share our experiences at the University of Maine advanced computational research center for natural systems. Our research area is to develop analytical and large scale numerical tools to understand turbulence in real life applications. With my expertise in the areas of numerical methods and fundamental fluid dynamics, our team has worked on developing direct numerical simulation (DNS) methodology to simulate transitional/turbulence flow over complex boundary (such an rough-wall). Development of DNS is very involved and it requires a good understanding of (a) immersed body techniques (b) multigrid methodology (c) numerical analysis (d) high performance computing and parallelization issues for supercomputing applications (e) Computational Fluid Dynamics (CFD) (f) partial differential equations
We develop DNS tools and use these large-scale simulations to study (a) Bio-Fluid Dynamics problems (as flow in coronary artery becomes turbulent when the disease progresses) (b) Coastal Applications (in the ocean and rivers). The simulations are highly accurate and well resolved in space and time. The simulations take on an average 3-7 days and produce 1-5 gigabytes of detailed data. We perform detailed statistical and flow visualization analysis to understand the basic mechanisms, turbulence structures, and the flow alterations in these problems.
