Talk Title: Solving Heat Transfer and Fluid Flow Problems with Reduced Order Models and Neural Networks

Speaker: Dr. Zilong Song Department of Math & Stat, USU

Abstract: The friction stir welding process can be modelled using a system of heat transfer and Navier-Stokes equations with a shear dependent viscosity. Finding numerical solutions of this system of nonlinear partial differential equations over a set of parameter space, however, is extremely time-consuming. Therefore, it is desirable to find a computationally efficient method that can be used to obtain an approximation of the solution with acceptable accuracy. In this talk, we present a reduced basis method for solving the parametrized coupled system of heat and Navier-Stokes equations using a proper orthogonal decomposition (POD). In addition, we apply a machine learning algorithm based on an artificial neural network (ANN) to learn (approximately) the relationship between relevant parameters and the POD coefficients. Our computational experiments demonstrate that substantial speed-up can be achieved while maintaining reasonable accuracy.

Science Unwrapped - Seeing Science

Panel Discussion/Presentation | Science Unwrapped

Inquiring minds of all ages are invited to Science Unwrapped, the public outreach program of USU's College of Science. Featured speaker is USU data scientist Kevin Moon, who presents "Seeing Science: Using Machine Learning to Visualize Data" at 7 pm in the Emert Auditorium (ESLC 130) of the Eccles Science Learning Center on USU's Logan campus. Admission is free. Dr. Moon's talk will be recorded and posted on Science Unwrapped's website following the talk: www.usu.edu/science/unwrapped

Due to pandemic restrictions, hands-on learning activities following the talk will not be offered in-person at this time. We encourage our guests to visit our website for video learning activities: https://www.usu.edu/unwrapped/learning-activities/index
