The force on a bubble, drop, or particle in arbitrary time-dependent motion at small Reynolds number [PDF]
, 1993 The hydrodynamic force on a body that undergoes translational acceleration in an unbounded fluid at low Reynolds number is considered. The results extend the prior analysis of Lovalenti and Brady [to appear in J. Fluid Mech.

Journal of Fluid Science and Technology, 2015 We investigated the influence of the airfoil geometry on the performance of the plunging airfoil numerically. In the present study, two circular arc airfoils with the different thickness were used and the numerical calculations were carried out within ...

Optimization of Sluice Gate under Fatigue Life Subjected for Forced Vibration by Fluid Flow
Journal of Mechanical Engineering, 2018 A ‘Sluice’ is a water-flow control gate works with sliding. So, it’s a mill race, flume or a penstock, channelling water towards a water mill, traditionally a wood or metal barrier sliding in grooves that are set in the sides of the waterway.

Effect of 3-Dimensional Airfoil Shape on Unsteady Fluid Forces in Pitching Motion
Journal of Fluid Science and Technology, 2010 A quasi-steady-state approach towards predicting the fluid forces acting on a hand under unsteady conditions yielded errors. The actual motion of a hand in swimming is obviously unsteady, and time-dependent fluid forces must be considered. The purpose of

Dramatic effect of fluid chemistry on cornstarch suspensions: linking particle interactions to macroscopic rheology [PDF]
, 2017 Suspensions of cornstarch in water exhibit strong dynamic shear-thickening. We show that partly replacing water by ethanol strongly alters the suspension rheology.
