Jarred and Samantha’s programs both involve the special turbulence structure created by the impacts of impermeable surfaces on the structure of energy-dominant wall-bounded turbulence eddies. It is in this “surface layer” region that wind turbines operate in the atmospheric boundary layer. I will present key new knowledge extracted from high-fidelity large-eddy simulations by Jarred Kenworthy to understand the nonsteady responses of the wind turbine rotor to the passage of atmospheric surface layer turbulence eddies, with consequent impacts on the wind turbine drivetrain. Jarred’s research shows that strong turbulence-generated nonsteady forcing of the main bearing may underlie the currently excessive levels of main bearing failure.</p><p>A key characteristic of surface layer turbulence is the linear growth of integral scale eddy size with distance from the impermeable surface, a key element in what is commonly referred to as “law-of-the-wall” (LOTW) in turbulent boundary layer scaling. I shall describe key elements in a far-reaching fundamental study of surface layer scaling carried out by Samantha Sheppard within a unique experimental program at the University of Colorado Boulder and the Laboratoire de Mécanique des Fluides de Lille in France. We learn that linear scaling of energy-dominant eddy size is generalizable to wider classes of wall-bounded turbulent flows than previously appreciated, extending key LOTW scaling arguments beyond the classical flat-plate turbulent boundary layer for they were developed.</p><p><strong>Bio:</strong> James Brasseur (Jim) is Research Professor of Aerospace Engineering Sciences at the University of Colorado Boulder.

A major error source for GNSS is multipath propagation and mitigating these errors is a major concern in high-accuracy positioning applications like survey, aircraft landing, and precision construction and agriculture. This talk presents an introduction to what multipath is, how it affects GNSS measurements, and ways to mitigate its effects. The use of carrier smoothing of code pseudorange measurements is discussed as an effective multipath and noise mitigation technique that does not require access to the inner workings of the receiver like other mitigation techniques require. Recent developments in approaches to statistically model multipath errors as stochastic processes and how the multipath error statistics are affected by carrier-code smoothing will be introduced. These techniques are useful in safety of life applications, like aviation navigation, where it is necessary to have statistical bounds for error sources. &nbsp;</p><p><strong>Biography: </strong>Dr. Gary McGraw is a systems engineering consultant, specializing in Positioning, Navigation and Timing (PNT).

In this talk, we will introduce a state-of-the-art scientific machine learning paradigm - differentiable physics (DiffPhys). DiffPhys can be considered a system identification paradigm that can be applied to determine neural network approximations of governing laws given data. It can also be used to improve first-principles-based simulations of physical phenomena by learning corrections to governing laws (for instance for closure modeling in multiscale applications). Notably, optimizing these neural networks necessitates a differentiable programming paradigm where gradients of a loss function can be propagated through a numerical solver. In this talk, we will introduce DiffPhys algorithms that (1) can learn models for dynamical systems from sparse data, (2) efficiently compute sensitivities for systems exhibiting deterministic chaos, (3) leverage graph neural networks for geometry-invariant learning, and (4) provide physically meaningful interpretations for neural network behavior thereby engendering scientific discovery. We will demonstrate the capabilities of DiffPhys on canonical and realistic scientific computing problems and close with a discussion of the future possibilities of this approach.</p><p><strong>Bio: </strong>Romit Maulik is an Assistant Professor of Data Science in the College of Information Sciences and Technology at Pennsylvania State University and a Joint Appointment Faculty at the Mathematics and Computer Sciences Division at Argonne National Laboratory (Argonne).

This ambitious and collaborative initiative is dedicated to tackling the computational challenges inherent in the development of hypersonic systems. The team’s primary goal is to design a computationally efficient framework for multi-physics design analysis and optimization under uncertainty, harnessing the power of surrogate modeling techniques to achieve remarkable efficiency gains. The lecture will begin with a comprehensive yet succinct overview of the global research effort, offering insights into the project’s objectives, broader impact, and the computational obstacles it seeks to overcome. Among these challenges are the surrogate modeling of quantities of interest versus spatio-temporal fields, the complexities of low-dimensional modeling in the presence of shocks, shock-shock and shock-boundary layer interactions, turbulence, and the intricacies of training surrogate models in high-dimensional parameter spaces for coupled vehicle-trajectory problems and optimization. The discussion will then shift to recent contributions by the speaker, including advanced nonlinear projection-based reduced-order models that address the closure error in the latent space using a deep learning approach. These models have been validated for hypersonic benchmark flow problems and have led to the development of an efficient global optimization method. Finally, the lecture will explore the application of these methods to simulate hypersonic flight dynamics and optimize trajectory planning, demonstrating their potential for advancing the design and analysis of hypersonic systems.&nbsp;</p><p><strong>Bio: </strong>Charbel Farhat is the Vivian Church Hoff Professor of Aircraft Structures in the School of Engineering at Stanford University, where from 2008 to 2023, he chaired the Department of Aeronautics and Astronautics.
