Network Science for Fluid Mechanics 

Seminar Series

A seminar series for fluid mechanicians & network scientists

The goal of this seminar series is to bring researchers in the fields of network science & fluid mechanics together from across the globe.

Organizers:

Samuel Douglass (University of Nevada, Reno)

Muralikrishnan Gopalakrishnan Meena (Oak Ridge National Laboratory)

Aditya Nair (University of Nevada, Reno)

Kunihiko Taira (University of California, Los Angeles)


There is growing interest in using network science and graph theory for analyzing high-dimensional fluid flow problems. The highly nonlinear nature of interactions in fluid flows pose a challenging task of understanding and controlling them. Network science can help in characterizing fluid flow time-series data, provide measures to reveal the relative importance of fluid flow nodes, and enable interaction-based model-reduction for prediction and control of fluid flows. 

This seminar series brings together experts from both the fields of network science (and graph theory) and fluid mechanics, who might benefit from applying such techniques to complex fluid flow problems. We are planning to have talks both on the theoretical aspects of network science as well as the applied aspects related to fluid mechanics. This series presents an opportunity to foster collaborations as well as ask questions to the experts on the applicability of their methodologies to fluid flow problems.
