Deciphering the drag force in complex fluids

We feel the drag force from air while walking, jogging or riding a vehicle, and we feel the drag force from sand while walking on the beach. Combining experiments, numerical simulations and theory, physicist Kai Huang addresses the question “How can we predict the trajectory of an object thrown into granular materials, such as sands, powders and grains?” in Nature’s Scientific Reports. The work sheds light on a fundamental understanding of drag force in complex fluids.
