Alexander Metelkin and Bernhard Vowinckel: New Findings on Predicting Drag Forces on Particles.
The snapshot of the DNS data set used for training.
A recent study by Alexander Metelkin & Bernhard Vowinckel presents a data-driven model to predict hydrodynamic forces on spherical particles in flow. Using local volume fractions as input to a neural network trained on pr-DNS data, the method improves accuracy over position-based models and adapts to particles of varied size and shape.
