Study on the effect of acoustic wave droplet collision-coalescence process is interesting and helps to better understand agglomeration mechanism. This study designs carries out a microscopic experiment investigate wall process. The derived images droplets under action different sound waves at moment are processed analyzed by binaryzation with iterative threshold, cavity filling, morphological o...

Agglomeration of fine solid particles under the excitation external acoustic field has potential applications in ultra-low emission combustion pollutants. It is expected that performance particle agglomeration can be improved by adding large sized liquid droplets. According to dynamic process agglomeration, including motion, collision, and rebound, a model for gas-liquid-solid three phase syste...

in recent years, the studies of location play a key role in success and stability of economic activities. location studies are under consideration in both national and international levels. meanwhile, identification of goals and methods of solving location problems have significant importance. the purpose of this paper is to examine spatial distribution of economic activities in 14 zones of esf...

This paper examines the agglomeration benefits of a transportation improvement in a city by modeling the microstructure of urban agglomeration based on monopolistic competition of differentiated intermediate products. Properly extended to include variety distortion in addition to price distortion, Harberger’s measure of excess burden yields the agglomeration benefits. The agglomeration benefits...
