Abstract

Computational Fluid Dynamics simulations and Machine Learning models are useful predictions tools that have the potential to work even better when used together. This paper presents a physics- based machine learning approach that supplements standard regression basis functions, such as polynomials, with simple physical models of the system. This mitigates the data dependence of machine learning predictions, and the associated computational cost of generating the training set simulations. We illustrate this method by increasing the accuracy of roll-damping power coefficient predictions by 50 to 200% using O(10) training examples.
