Overlooked 'history force' may skew particle motion by up to 60% in shaken fluids

Physicists at the University of Bayreuth have investigated the so-called Basset-Boussinesq history force acting on particles in fluids. Due to the difficulty of calculating it, this force is often neglected-a fact that Bayreuth doctoral researcher Frederik Gareis already identified as a secondary school pupil during a student research project with his supervisor. The researchers report their new findings on the history force in Physical Review Fluids.
