Summary of Research
I research the applications of machine learning tools to fluid dynamics and fluid-structure interaction problems. I'm developing robust and real-time flow physics simulations using high performance computing, domain decomposition, and model order reduction techniques. The recent progress within the field of machine learning has inspired this interdisciplinary study at the crossroads of mechanical engineering, aerospace, and computational sciences.
A computational fluid dynamics (CFD) analysis is spatially local and involves computing a differential equation on a large number - often millions - of discrete points throughout a computational domain. Although CFD analyses are a vast improvement over wind tunnel or rig testing alone, they are computationally expensive, which is limiting to the engineer trying to rapidly iterate and optimize a design.
A potential solution to the problem of developing real-time methods for predicting highly non-linear fluid solutions is model order reduction. In the offline stage of model order reduction, solution vector snapshots of full CFD simulations are pre-calculated using high performance computing. In the online stage, a residual minimization problem within the pre-calculated reduced order bases predicts new solutions in real time.
