Neural-Network-based Viscosity Closure for Non-Newtonian Multiphase Flows
Suresh Murugaiyan, Claire L. Nelson, Dhruv Gamdha +11
Materials used in polymer-based additive manufacturing processes, such as Digital Light Processing (DLP) and direct ink writing (DIW), typically exhibit non-Newtonian rheology. Car…
Predicting Time-Dependent Flow Over Complex Geometries Using Operator Networks
Ali Rabeh, Suresh Murugaiyan, Adarsh Krishnamurthy +1
Fast, geometry-generalizing surrogates for unsteady flow remain challenging. We present a time-dependent, geometry-aware Deep Operator Network that predicts velocity fields for mod…
A Shifted Boundary Method for Thermal Flows
Cheng-Hau Yang, Guglielmo Scovazzi, Adarsh Krishnamurthy +1
This paper presents an incomplete Octree mesh implementation of the Shifted Boundary Method (Octree-SBM) for multiphysics simulations of coupled flow and heat transfer. Specificall…
MPFBench: A Large Scale Dataset for SciML of Multi-Phase-Flows: Droplet and Bubble Dynamics
Mehdi Shadkhah, Ronak Tali, Ali Rabeh +7
Multiphase fluid dynamics, such as falling droplets and rising bubbles, are critical to many industrial applications. However, simulating these phenomena efficiently is challenging…
Simulating incompressible flows over complex geometries using the shifted boundary method with incomplete adaptive octree meshes
Cheng-Hau Yang, Guglielmo Scovazzi, Adarsh Krishnamurthy +1
We extend the shifted boundary method (SBM) to the simulation of incompressible fluid flow using immersed octree meshes. Previous work on SBM for fluid flow primarily utilized two-…
FlowBench: A Large Scale Benchmark for Flow Simulation over Complex Geometries
Ronak Tali, Ali Rabeh, Cheng-Hau Yang +10
Simulating fluid flow around arbitrary shapes is key to solving various engineering problems. However, simulating flow physics across complex geometries remains numerically challen…
