Estimation of Shear-Induced Lift Force in Laminar and Turbulent Flows
TL;DR: In this article, the authors demonstrate that direct numerical simulations coupled with interface tracking methods can be used to estimate interfacial forces in two-phase flows and demonstrate that the results can be extended to two-dimensional flows.

The lateral migration of relative large bubble in simple shear flow in water
TL;DR: In this paper, the lateral migration velocity and quasi-steady lift force were obtained by linear fitting of bubble trajectories in a semi-spherical cup and the results showed that bubble shape parameters, rising velocity and drag force were stayed at same level in shear flow as in still water.

Experimental investigation of single small bubble motion in linear shear flow in water
TL;DR: In this paper, the motion of small bubble in a simple shear flow in water was experimental studied and the results indicated that the lateral migration was coupled with the zigzag motion of bubble in the present experiment.

Evaluating the Euler-Euler approach for predicting a strongly 3D bubble induced recirculatory flow with OpenFOAM
TL;DR: In this paper, a two-phase unsteady Reynolds-averaged Euler-Euler (uRANS-EE) approach was used to predict bubble induced recirculatory flow in a laboratory tank of similar complexity to that expected in a full-scale grit-chamber.

Volume of fluid (VOF) method for the dynamics of free boundaries
C.W Hirt,B. D. Nichols +1 more
TL;DR: In this paper, the concept of a fractional volume of fluid (VOF) has been used to approximate free boundaries in finite-difference numerical simulations, which is shown to be more flexible and efficient than other methods for treating complicated free boundary configurations.

A continuum method for modeling surface tension
TL;DR: In this paper, a force density proportional to the surface curvature of constant color is defined at each point in the transition region; this force-density is normalized in such a way that the conventional description of surface tension on an interface is recovered when the ratio of local transition-reion thickness to local curvature radius approaches zero.

Bubbles, Drops, and Particles
TL;DR: In this paper, the authors evaluated the applicability of the standard κ-ϵ equations and other turbulence models with respect to their applicability in swirling, recirculating flows.

Solution of the implicitly discretised reacting flow equations by operator-splitting
TL;DR: In this article, a non-iterative method for handling the coupling of the implicitly discretised time-dependent fluid flow equations is described, based on the use of pressure and velocity as dependent variables and is hence applicable to both the compressible and incompressible versions of the transport equations.

The lift on a small sphere in a slow shear flow
TL;DR: In this article, it was shown that a sphere moving through a very viscous liquid with velocity V relative to a uniform simple shear, the translation velocity being parallel to the streamlines and measured relative to streamline through the centre, experiences a lift force 81·2μVa2k½/v½ + smaller terms perpendicular to the flow direction, which acts to deflect the particle towards the streamline moving in the direction opposite to V.
