Droplet deposition in radial turbines [PDF]
European Journal of Mechanics - B/Fluids, 2017 In this paper droplet deposition in radial turbines used for waste heat recovery in the chemical industry is investigated. During expansion, the water vapour in the working fluid undergoes sub-cooling, at a certain point a cloud of fine droplets begins to form and a fraction of these droplets is deposited on the blade surfaces.

Controlling droplet deposition with surfactants
Physical Review Fluids, 2021 Droplets impacting on a surface are key to a wide range of applications such as spray deposition and inkjet printing. Yet, a full understanding of how they spread and retract is still lacking. Surfactants are often added to improve spreading and coverage of aqueous solutions, resulting in variations of the surface tension at timescales beyond the reach

Spherical Droplet Deposition—Mechanistic Model [PDF]
Coatings, 2021 In the currently existing physical models of wetting a solid substrate by a liquid drop, the contact angle is determined on the basis of the equilibrium of forces acting tangentially to the wetted surface at any point in the perimeter of the wetted area, ignoring the forces (or their components) acting perpendicular to this area.

Lattice Boltzmann simulation of droplet behaviour in microfluidic devices [PDF]
, 2009 We developed a lattice Boltzmann model to investigate the droplet dynamics in microfluidic devices. In our model, a stress-free boundary condition was proposed to conserve the total mass of flow system and improve the numerical stability for flows with ...
