AbstractThe investigation of liquid bridge force acting between wet particles has great significance in many fields. In this article, the exact solution of capillary force between two unequal-sized spherical particles is investigated. Firstly, The Young-Laplace equation with moving boundary is converted into a set of ordinary differential equations with two fix point boundary using variable substitution technique, in which the gravity effects have been neglected. The geometry of the liquid bridge between two particles is solved by shooting method. After that, the gorge method is applied to calculate the capillary-bridge force that is consists of contributions from the capillary suction and surface tension. Finally, the effect of various parameters including distance between two spheres, radii of spheres, and contact angles on the capillary force are investigated. It is shown that the presented approach is an efficient and accurate algorithm for capillary force between two particles in complex situations.

Drainage Effect

Spreading and drainage of liquid over particle surface in a liquid bridge between two particles has been modeled to study the influence of temperature of particle and initial kinetic energy of liquid mass remain attached between two particles on impingement of droplet to form liquid bridge on liquid spreading. The spreading and drainage of liquid bridge is a key factor for particle agglomeration, which is commonly encountered in many industrial processes such as petroleum refinery, spray coating and flocculation which involve the collision of droplet and solids particles. A model based on mass and energy conservation of liquid trapped between two particles has been proposed to estimate the surface area of particle wetted by the liquid drainage and the thickness of liquid film under the influence of heat transfer to the liquid film from hot solid particles and initial kinetic energy of spreading liquid. The Laplace-Young model of liquid bridge is solved with discrete method to obtain the volume and surface change of liquid bridge due to spreading and drainage effect. The proposed model is capable of determining transient surface coverage of spreading liquid, liquid film thickness and its temperature. The influence of some key parameters, such as initial kinetic energy of spreading liquid, initial temperature of particle on the wetting thickness and wetting area is also investigated.
