Particle engineering via surface modification during micronization for pharmaceutical applications
… method was developed to estimate the granular Bond number to evaluate the performance of dry coating. This technique eliminates the usual need of detailed, time consuming particle scale characterization via atomic force microscopy. Estimated Bond numbers were compared and verified with those …

Three-dimensional solitary waves in dispersive wave systems
… only in the strong-surface-tension regime (Bond number, B > 1/3), a condition that limits the water depth to a few mm. In the present thesis, a new class of lumps is found that is possible under less restrictive physical conditions. Rather than long waves, these lumps bifurcate from …

Development and application of Lattice Boltzmann and accurate volume of fluid numerical techniques on graphics processing units
… The effects various dimensionless parameters (Bond number, Morton number, and confinement ratio) were investigated to understand the terminal velocity and shape of a bubble. Subsequently, bubble dynamics in variable viscosity fluid were investigated where the effects of power-law index, Bond …

Displacement of Fluid Droplets From Solid Surfaces
… is to predict the yield conditions (capillary number Ca) as a function of physical parameters including viscosity ratio lambda, Bond number B d and advancing and receding contact angles thetaA and thetaR. To determine the yield conditions, we conduct a computational study employing a spectral …

Free surface flows over submerged obstructions
… the forced wave is determined by the Froude and Bond numbers and the orientation of the disturbance. When a second disturbance is placed upstream in the pure gravity critical case, trapped waves have been found between the disturbances. However, when surface tension is included, trapped waves are …

Thermo-Capillary Driven Flow Under the Influence of Rotation and Magnetic Fields
… the main parameters are the solutal Marangoni number Mc, representing the surface tension gradient force and the Taylor number Ta representing the rotational effect. For given values of Mc, certain values of Ta were detected where the Sherwood number Sh, representing the convective solute flux, …

Interface pinning of CO₂ gravity currents
… to gravity, as measured by the inverse of the Bond number. We demonstrate that capillary pressure hysteresis in porous media is caused by the fundamental difference in pore-scale invasion patterns between drainage and imbibition. In addition, we propose a sharp interface gravity current model …

A Spatial Dynamic Approach to Three-Dimensional Gravity-Capillary Water Waves
… determined by two non-dimensional constants: the Bond number b and λ (the inverse of the square of the Froude number). The property of Sobolev spaces and the spectral analysis show that the spectrum of the linear part consists of isolated eigenvalues of finite algebraic multiplicity and the number …

Low-Gravity Sloshing in Spherical Tanks: Experimental Investigation Toward Numerical and Analytical Modeling
… sloshing in a spherical tank for a range of Bond numbers below 50. The force exerted on the tank walls is recorded, and the position of the center of mass is reconstructed from free surface tracking to analyze the fluid’s response in both time and frequency domains. Video imaging and Bond …

Fluid mechanics of liquid drops and thin-films
… frequency of an inviscid sessile drop with small Bond number (surface tension dominates gravity) and a fixed contact line on a flat horizontal plate. The governing equations are expressed in terms of a toroidal coordinate system which yields solutions involving hypergeometric functions. The …

Instabilities of rotating jets
… is characterized in terms of the rotational Bond number, B₀ = ... . The critical B₀ may be as low as 6, if there is a strong bias imparted by vibration of the table at an appropriate frequency, but for a perfectly quiescent rotating jet the second mode does not become dominant until a higher …

Numerical study of the nonlinear dynamics of the acoustic drops and bubbles
… imposes an upper limit on the acoustic bond number that can be used, while the lower limit is set by the stability of translational motion. The static equilibrium shapes can be obtained by incorporating the artificial damping into the system. The static equilibrium shapes thus found …

Structure-property relationships in physical polymer gels
… polymer networks are included in a large number of materials where it is important to control and tune the rheological response of the material, particularly including responses to temperature, shear, or changes in the surrounding environment. Knowledge of the relationship between the …
