If we assume that the reflected field from the coverslip-buffer interface couples back into the laser with the same efficiency, κ, as the field that is reflected from the buffer-sphere interface, we can eliminate the dependence upon κ and we can use the ratio B o/ A to determine nsphere = 1.58.
In the traditional inward solidification model of a sphere, the interface temperature of liquid solid is considered as a constant freezing point, but majority of materials have a freezing temperature range and the freezing temperature descends with the change of liquid solid two phase composition.
The red hollow and solid spheres at interface represent the unoccupied and occupied interface state, respectively.
An improved version of the height function technique is proposed, based on introducing a correction of the height function discretization error estimated from the local osculating spheres at interface points.
Ultrasonic cleaning is modeled as a plane wave striking a sphere at the interface between a solid and a fluid (an axisymmetric fluid-structure interaction problem).
The model predicts that, at surfactant concentrations above those that make the bubble behave as a solid sphere, the bubble interface is mobile and the flow separation point moves around to the top of the bubble.
From the data, the height of the center of the sphere above the interface, h o, was determined to be h o = 0.005 μm.
The most active sites were on the surface of the spheres or in the interface between the spheres and the solution.
The interface spheres are clustered to identify binding sites.
For a sphere at the liquid gas interface, the sphere is stable at the position where the forces on the tangential line around the contact line are balanced [10, 26].
The subject of this work is the creeping motion of liquid caused by steady translation and rotation of a solid sphere close to an interface between two fluid phases.
