We study traffic congestion by analyzing a one dimensional traffic flow model. Developing an asymptotic method to investigate the long time behavior near a critical point, we derive the modified Korteweg-de Vries (mKdV) equation as the lowest order model. There are an infinite number of kink solitons to the mKdV equation, while it has been found by numerical simulations that the kink pattern ar...

Quality regulation of the combustion process inside the furnace is the basis of high demands for increasing robustness, safety and efficiency of thermal power plants. The paper considers the possibility of spatial temperature distribution control inside the boiler, based on the correction of distribution of coal over the mills. Such control system ensures the maintenance of the flame focus away...

The purpose of the present work was to study the differentiation of states of typical fluidization (single bubble, multiple bubble and slugging) in a gas-solid fluidized bed, using spectral analysis of pressure fluctuation time series. The effects of the method of measuring (differential and absolute) pressure fluctuations and the axial position of the probes in the fluidization column on the i...

Here, a unified 3D numerical model of gas-liquid two-phase flow in horizontal pipe was established using the interface capture method based on open source software package OpenFOAM. Through simulation natural slugging and development process slug under different working conditions, motion, phase structure, pressure velocity field distributions liquid were fully developed analyzed. The results a...

In this study, the question of how fragmentation and deformation granules during compression can be linked to tableting performance dry granulated powders is addressed. Granulated a systematically varied composition plastic brittle material were prepared by slugging thereafter compacted into tablets. The tablet's micro-structure, porosity, tensile strength assessed; moreover, relationships betw...
