Application of modified Navier-Stokes equations to determine the unsteady force effects of a heterogeneous liquid [PDF]
The article is focused on calculating the force effects of a heterogeneous liquid on pipe walls. The solution is based on the concentration of solid particles. The base fluid is assumed to be incompressible.

The force on a bubble, drop, or particle in arbitrary time-dependent motion at small Reynolds number [PDF]
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.

Flutter analysis and wind-tunnel experiments of a flat plate suspended by wires
In the construction work, flat plates for building materials are transported by a suspension mechanism using wires in air flow. Then, a flutter could be caused to the suspended plates due to the interaction between plate motion and fluid flow.
