It has been widely reported that the sintering productivity and bed permeability would be reduced when adopting ultra-deep sintering. To solve aforementioned problems, double-layer process with stand-support (DLSP-S) is proposed in this research to achieve of a 1000 mm bed. The results showed compared process, DLSP-S improved yield from 64.53% 1.76 t·m−2·h−1 66.74% 2.12 t·m−2·h−1, respectively....

Air quality is highly related to the health of a human being. Urban morphology has significant influence on air quality; however, specific relationship between urban characteristics and at neighborhood scale yet be investigated, especially vegetation effect PM2.5 concentration diffusion. The relevant morphological parameters based affected pathways were selected, sensitivity degree laws selecte...

Analyzing a free boundary problem for harmonic functions in an infinite planar domain, we prove that in a solitary water wave each particle is transported in the wave direction but slower than the wave speed. As the solitary wave propagates, all particles located ahead of the wave crest are lifted, while those behind it experience a downward motion, with the particle trajectory having asymptoti...

The hydrodynamics in a 152 mm ID bubbling fluidized bed filled with 500-600 μm glass beads have been simulated using the computational fluid dynamics (CFD) code Fluent 6.3, and the results are compared to experimental data obtained using pressure measurements and 3D X-ray computed tomography. The grids in a Cartesian coordinate system used in simulations are made by 2D (8×8 mm, 4×4 mm, 2×2 mm, ...

This research aims to find a suitable transportation rate formula for bed load. Laboratory experiments were conducted in flume monitoring and measuring the of sediment particles (bed load) which move by jumping, rolling, or sliding within flume. study included two parts. The first part is experimenting using tracking particles' movement analysing images taken camera. measurements that have been...

In this paper, experimental data on the drying kinetics of corn in a packed and fluidized bed are presented. Experimental research was conducted on a laboratory apparatus. Corn was used as a material because of its significance in agriculture and the food industry. An analysis of the influence of the operational parameters (the drying medium velocity i. e. the flu...

Waves are main characteristics of seas that produce by wind. Importance of the study of waves and recognizing the wave climate in the coastal zone management that the waves are the most important influence on the design and implementation of all projects. Wave are main boundary condition in dynamic loading and structural calculations and hydraulic coastal structures. Height of waves are the mos...
