Optical levitation of spheres: analytical development and numerical computations of the force equations
نویسندگان
چکیده
The force that is produced from the momentum change of a stream of photons incident upon micrometer-sized spheres is developed from a ray-optic model. The resulting force component expressions, axial and radial with respect to the photon stream center and incident direction, are in a form that makes them suitable for computer modeling of the levitation phenomena. Simulated results presented are in excellent agreement with published experimental observations.

Using the mean-value theorem for integrals we tried to solved the nonlinear integral equations of Hammerstein type . The mean approach is to obtain an initial guess with unknown coefficients for unknown function y(x). The procedure of this method is so fast and don't need high cpu and complicated programming. The advantages of this method are that we can applied for those integral equations whi...

In this study, the momentum and energy equations of laminar flow of a non-Newtonian fluid are solved in an axisymmetric porous channel using the least square and Galerkin methods. The bottom plate is heated by an external hot gas, and a coolant fluid is injected into the channel from the upper plate. The arising nonlinear coupled partial differential equations are reduced to a set of coupled no...
