Evaporation-driven vapour microflows: analytical solutions from moment methods

Numerical Simulation of Mixed Electroosmotic/pressure Driven Microflows

A spectral element algorithm is developed to analyze mixed electroosmotic=pressure driven  ows in complex two-dimensional geometries. The new algorithm exhibits spectral accuracy in resolving thin electric double layers. Mixed electroosmotic=pressure driven  ows are simulated in straight channels. Electrokinetic pumping and the means of producing large pressure gradients in microchannels are ...

Electro-osmotic and pressure-driven flow of viscoelastic fluids in microchannels: Analytical and semi-analytical solutions

Evaporation-driven ring and film deposition from colloidal droplets

Evaporating suspensions of colloidal particles lead to the formation of a variety of patterns, ranging from a left-over ring of a dried coffee drop to uniformly distributed solid pigments left behind wet paint. To characterize the transition between rings and uniform deposits, we investigate the dynamics of a drying droplet via a multiphase model of colloidal particles in a solvent. Our theory ...

Analytical solutions for the neutron transport using the spectral methods

We present a method for solving the two-dimensional equation of transfer. The method can be extended easily to the general linear transport problem. The used technique allows us to reduce the two-dimensional equation to a system of one-dimensional equations. The idea of using the spectral method for searching for solutions to the multidimensional transport problems leads us to a solution for al...

Methods of Measuring the Evaporation of Water from Animals

DURING the past five years this problem of the evaporation of water from animals has attracted considerable attention, particularly from entomologists. Considerable advances have been made, but when the technique of various workers is examined from a physical standpoint it is difficult to see how far laboratory results can be applied to ecological problems in the field. During the last two year...
