Turbulence-particle interactions on surfaces
The physics of adhesion and detachment of particles in ventilation ducts is important to understand and control contaminant and pathogen dispersal indoors. This thesis presents an experimental characterization of parameters which affect the resuspension of settled micro-particles and spores in a …

Richtmyer-Meshkov instability with reshock and particle interactions
… parameters: the mass loading of the particles and the Stokes number. The model is compared to the numerical predictions under two types of conditions: a shock wave hitting (1) a perturbed species interface surrounded by particles, and (2) a perturbed particle cloud. In the first type …

Wave-particle interactions in the solar wind and solar flares
<p>Resonant interactions between particles and plasma waves play an important role in both the solar wind and solar flares. The dynamics of plasma turbulence in these settings controls the strength of the interactions, by determining the amplitudes of the small-scale electromagnetic fluctuations …

Modeling bubble-particle interactions in flotation using hydrophobic solid surfaces
… hydrophobic force parameters of the asymmetric interactions, K132, can be predicted from those of the symmetric interactions, K131 and K232, using a geometric mean combining rule. Asymmetric force measurements were conducted between a hydrophobized glass sphere and a bare silica plate in …

Theoretical and experimental investigation of particle interactions in pharmaceutical powder blending
… and therefore higher manufacturing costs. Since particles are the basic unit of powder flow, a fundamental understanding of the crucial particle characteristics and particle interactions is essential for a good prediction and control of the blending process. In this work, inter-particle adhesion …
