Parametric forcing approach to rough-wall turbulent channel flow [PDF]
, 2012 The effects of rough surfaces on turbulent channel flow are modelled by an extra force term in the Navier–Stokes equations. This force term contains two parameters, related to the density and the height of the roughness elements, and a shape function ...

Behavior of axial thrust caused by intake sump vortices in a vertical mixed flow pump
Nihon Kikai Gakkai ronbunshu, 2017 Axial thrust forces acting on an impeller of a diffuser type mixed flow pump and the behavior of the axial thrust generated by the vortex occurrence in a pump intake sump were studied.

Particle Dynamics in a Viscous Fluid Under the Action of Acoustic Radiation Force [PDF]
, 2017 Complex dynamics of small particles under the action of acoustic radiation force is considered. This work extends the previous studies of Ostrovsky & Sarvazyan (2009) and Ostrovsky (2015) in two aspects.

Fluid forces control endothelial sprouting [PDF]
Proceedings of the National Academy of Sciences, 2011 During angiogenesis, endothelial cells (ECs) from intact blood vessels quickly infiltrate avascular regions via vascular sprouting. This process is fundamental to many normal and pathological processes such as wound healing and tumor growth, but its initiation and control are poorly understood. Vascular endothelial cell growth factor (VEGF) can promote

Experimental validation of unsteady models for fluid structure interaction: Application to yacht sails and rigs [PDF]
, 2012 • We present full scale measurements on a yacht sailing upwind in moderate head swell • We highlight the unsteadiness of the loads : peaks may be twice the mean value • The dynamic behavior differs from the steady state : hysteresis loop • Experimental ...

Fluid Force on Accelerating Bodies
Coastal Engineering 1972, 1972 The force exerted by a liquid on a moving body always depends on the preceding velocity and acceleration of the body. The Basset-Lai equation, derived from the linearized equation of motion, gives the force on spheroids when convective acceleration of the water particles may be ignored.

Entropic forces between fluid layers [PDF]
Proceedings of the National Academy of Sciences, 2013 In PNAS, Freund (1) analyzes the problem of the entropic interactions between flexible lipid bilayer membranes at both small and large separations. A main conclusion is that, over a large range of separations, the repulsive force essentially varies with the inverse of the separation, c−1, between the membranes (bilayers), in marked contrast to the ...

Cell Adhesion: A surprising cohesive force [PDF]
, 2007 When an experimentalist or a biological mechanism applies an external force onto a cell chemically sticking to its substrate, a reacting "suction" force, due to the slow penetration of the surrounding fluid between the cell and the substrate ...

The Study about Drag Reduction of a Circular Cylinder with Grooves
Journal of Fluid Science and Technology, 2011 In this study, two kinds of circular cylinders which cut grooves to the cylinder surface for the purpose of cylinder drag reduction were produced. One of which is the circular cylinder which set 2 grooves in the cylinder upstream side, and other is the ...
