Jornada SEMNI 8 de abril 2022. R. Vinuesa

El próximo 8 de abril, a las 12 de la mañana, hemos organizado una nueva jornada SEMNI. En esta ociasión contaremos con la presencia de nuestro compañero Ricardo Vinuesa, del KTH de Estocolmo. La conferencia será retransmitida por nuestro canal de YouTube, como de costumbre. Esperamos contar con vosotros para disfrutar de un tema de tanta actualidad:

Título: Modelling and controlling turbulent flows through deep learning

Abstract: 

The advent of new powerful deep neural networks (DNNs) has fostered their application in a wide range of research areas, including more recently in fluid mechanics. In this presentation, we will cover some of the fundamentals of deep learning applied to computational fluid dynamics (CFD). Furthermore, we explore the capabilities of DNNs to perform various predictions in turbulent flows: we will use convolutional neural networks (CNNs) for non-intrusive sensing, i.e. to predict the flow in a turbulent open channel based on quantities measured at the wall. We show that it is possible to obtain very good flow predictions, outperforming traditional linear models, and we showcase the potential of transfer learning between friction Reynolds numbers of 180 and 550. We also discuss other modelling methods based on autoencoders (AEs) and generative adversarial networks (GANs), and we present results of deep-reinforcement-learning-based flow control.
