Lift force acting on a levitating drop over a moving wall
Nihon Kikai Gakkai ronbunshu, 2015 We experimentally investigate a levitating drop over a moving wall. Between the drop and the wall, a thin air film exists. In this study particular attention is given to examine whether the lift force generated inside the thin air film is dominant force ...

A Potential Field Description for Gravity-Driven Film Flow over Piece-Wise Planar Topography
Fluids, 2019 Models based on a potential field description and corresponding first integral formulation, embodying a reduction of the associated dynamic boundary condition at a free surface to one of a standard Dirichlet-Neumann type, are used to explore the problem ...

A new resistance function for two rigid spheres in a uniform compressible low-Reynolds-number flow [PDF]
, 2006 The pressure moment of a rigid particle is defined as the trace of the first moment of the surface stress acting on the particle. We calculate the pressure moments of two unequal rigid spheres immersed in a uniform compressible linear flow, using twin ...
