Authors: Xie Shao Bo , Wei Lang
Published: May 2013

Prediction of vehicular operating speed is critical to evaluate the design consistency of road alignment. Elman neural networks are proposed to predict the truck’s 85th percentile operating speed. A total of 190 samples are collected from the two-lane rural roads and two factors are considered as input variables to the model including the curve radius and longitudinal slope. 100 samples are applied for training the networks to get the prediction model and the other 90 samples are used for the model validation. Additionally, the Elman neural networks are compared with back-propagation neural networks and linear regression, and the results show that the Elman neural networks are prior to the other two approaches and can be regarded as an alternative to predict truck’s operating speed.

Authors: Wang Hai Yan , Zhang Jian Xin
Published: May 2013

Dyeing textile’s information management system is the basis of accurate classification of color， machine studying methods have became a popular area of research for application in color classification. Traditional classification methods have high efficiency and are very simple ， but they are dependent on the distribution of sample spaces. If the sample data properties are not independent， forecast precision will been affected badly and internal instability will appear. An application of Gray-Relation for dyeing textile color classification has been designed， which offsets the discount in mathematical statistics method for system analysis. It is applicable regardless of variant in sample size， while quantizing structure is in agreement with qualitative analysis. On the basis of theoretical analysis， Dyeing textile color classification was conducted in the conditions of random sampling、 uniform sampling and stratified sampling. The experimental results proofs that by using Gray-Relation， dyeing textile color classification does not need to be dependent on sample space distribution， and increases the stability of classification.

The pressure fields and the load capacity of water-lubricated spiral groove thrust bearings with different groove molded lines were simulated by computational fluid dynamics. The results show that the spiral groove which can produce the best loading capacity and steadier pressure field is appropriate to water-lubricated spiral groove thrust bearing. The line spiral groove can be used for decrease the process difficult when the loading capacity require is low.

Authors: Chen Guang Hui , Liu Zheng Liang
Published: May 2013

The objective of the present work is to characterize and investigate the effect of aspect ratio and twist angle of elements on the pressure drop predictions in Kenics static mixers using three-dimensional CFD approach. Twenty different kinds of Kenics mixers have been characterized. The numerical approach took into account the relationship between pressure drop and aspect ratio and relationship between pressure drop and twist angle at high Reynolds number within the Kenics mixer, which was neglected in previous studies. It is found from the study that the pressure drop is the function of aspect ratio and twist angle with a specified geometry at a certain flow rate.

Authors: Duan Ji Hai , Guan Xing Xing
Published: May 2013

Through the numerical simulation method, the Reynolds stress turbulence model (RSM) was used to simulate the flow field of circumfluent cyclone separator with three different outer chamber heights. Three circumfluent cyclones (CFC), with different outer chamber heights, are compared with each other. Pressure fields, velocity fields and pressure drop have been investigated. The results show that in a certain range, the outer chamber height of circumfluent cyclone separator has an optimum value, which can have higher separate efficiency and lower pressure drop. This provides a strong theoretical basis for the local optimization design of the cyclone.
Vibration Parameter Analysis of Non-Harmonic Vibration Conveyor
Authors: Qin Zhi Ying , Liu Yao
Published: May 2013

For the non-harmonic vibration conveyor, a single-degree-of-freedom dynamics model is built for the horizontal motion of bulk materials, in which the dry friction force is piecewise nonsmooth. The effect on conveying velocity is studied for six vibration parameters in the excitation force with two harmonic components. The conveying velocity increases with the increase of frequency and amplitude, but the optimum frequency ratio is 2, and the optimum amplitude ratio approaches 1/3. The initial phase has no effect on conveying velocity, and the effect of phase difference is periodic, i.e. the forward conveying is best on phase difference π/2, and the backward conveying is best on phase difference -π/2.

The motion track of desulfurized fly ash in flue gas was simulated by means of Fluent software. The abrasion and deposition of desulfurized fly ash to inner surface and other internals inside of dense flow absorber were studied. The results show that, under the simulated condition, the flue gas streamline is uniform inside of dense flow absorber which is installed with the equipment of baffle plates and four-layer delta wing plates. The desulfurized fly ash could be distributed uniformly and the pressure loss is approximately 340Pa. The abrasion rate of desulfurized fly ash to No.1 baffle plate is higher and the distribution is relatively concentrated, however, the abrasion rate of desulfurized fly ash to other layers of baffle plate and delta wing plate is lower and the distribution is relatively uniform. Besides, the abrasion rate of the dense flow absorber top and the A-convex surface is higher as well. Most desulfurized fly ash deposits on the bottom of ash hopper and some deposits on parts of baffle plates and delta wing plates. The deposition rate of B-convex surface is higher than that of A-convex surface. In reality, the highly corrosive parts inside of dense flow absorber should adopt wear-resistant materials. Meanwhile, water content of desulfurized fly ash should be controlled to avoid hardening of desulfurized fly ash which is deposited.

This paper presents the numerical predictions of 3D CFD rotor computations of an 800mm diameter model of marine current turbine (MCT). In the paper CFD is applied to a rotor at stationary hydrodynamic conditions Simulations from the numerical prediction are compared with experimental measurements of the model of MCT which is experimented on in a cavitation tunnel and a towing tank. The experimental data includes measurements of power and thrust generated by the turbine, in both a cavitation tunnel and a towing tank, for a series of blade pitch settings and speeds. The numerical predictions show similar results and provide a satisfactory representation of the experimental turbine performance.

Published: May 2013

Many offshore and harbor structures are composed of cylindrical members. In this paper, the special case of shoaling breaking wave loads on a vertical cylinder is investigated in a tank. A segmented cylinder model with outer diameter of 0.204m and total height of 1m was built and tested. Also a 1:20 slope ramp was constructed in the tank to provide the shoaling effect. During the experiments the total force on each segment of the cylinder was measured and the water surface elevations at the cylinder and in deep water were also recorded. Studies on wave shapes and wave loads are presented here.
