RoboJEPA: Scaling Robotic Latent World Models
Artem Zholus, Nicolas Beltran-Velez, Jianhao Yuan +9
Latent world models have shown a remarkable ability to predict future states and to plan in the real world. In practice, however, we lack a principled way to estimate how their cap…
Implicit BDF2 dual time-stepping positivity-preserving entropy-stable schemes for unsteady compressible viscous flows
Mohammed Sayyari, Nail K. Yamaleev
This paper presents a rigorous extension of the explicit, high-order, positivity-preserving, and entropy-stable spectral collocation schemes developed in Upperman 2023 and Yamaleev…
Implicit dual time-stepping positivity-preserving entropy-stable schemes for the compressible Navier-Stokes equations
Mohammed Sayyari, Nail K. Yamaleev
We generalize the explicit high-order positivity-preserving entropy stable spectral collocation schemes developed in Upperman 2023 and Yamaleev 2023 for the three-dimensional (3D)…
High-resolution measurements and simulations of the flow through a packed bed and its freeboard region
Wojciech Sadowski, Mohammed Sayyari, Francesca di Mare +2
The present study focuses on the assessment of the performance of a Finite Volume Method based, particle-resolved simulation approach to predict the flow through a model packed-bed…
Large eddy simulation of flow in porous media: Analysis of the commutation error of the double-averaged equations
W. Sadowski, M. Sayyari, F. di Mare +1
The continuum approach employing porous media models is a robust and efficient solution method in the area of the simulation of fixed-bed reactors. This paper applies the double-av…
Development and analysis of entropy stable no-slip wall boundary conditions for the Eulerian model for viscous and heat conducting compressible flows
Mohammed Sayyari, Matteo Parsani, Lisandro Dalcin
Nonlinear entropy stability analysis is used to derive entropy stable no-slip wall boundary conditions for the Eulerian model proposed by Svärd (Physica A: Statistical Mechanics an…
Relaxation Runge-Kutta Methods: Fully-Discrete Explicit Entropy-Stable Schemes for the Compressible Euler and Navier-Stokes Equations
Hendrik Ranocha, Mohammed Sayyari, Lisandro Dalcin +2
The framework of inner product norm preserving relaxation Runge-Kutta methods (David I. Ketcheson, \emph{Relaxation Runge-Kutta Methods: Conservation and Stability for Inner-Produc…
