Measurements of concentration distribution of hydrogen jet using deflection of center of the laser spot

The main purpose of this work is to propose a new method to evaluate the concentration distribution of the hydrogen jet by using a He–Ne laser through the jet. This research attempts to apply the expression of concentration Gaussian distribution, the refraction formula of inhomogeneous refractive index medium, and the concentration inversion function to disclose the displacement of the center of the laser spot at different heights in the gas jet. The spot images of the laser beam passing through the gas jet at three vertical heights z = 10d, 20d, 30d, and different radial positions are obtained. The radial spatial asymmetry of the gas jet is also found in the experiment. Finally, the calculated concentration distribution curve and the fluent simulation curve, it is found that the two results are very similar. Our findings show that the error between the concentration distribution of this method and the simulated concentration distribution reaches 2.43%.     

Unerroric of control of mutual compliance of the efficiency of hydrogen engines of unmanned vehicles in the conditions of mass production

The issues related to the reliability of hydrogen engines of unmanned vehicles and increasing the efficiency of using hydrogen as fuel when using the method of its production during the decomposition of hydrogen-containing molecules of liquid-phase organic compounds in a plasma discharge under the action of intense ultrasonic exposure are considered. Experiments have shown that as a result of decomposition in the acoustoplasma discharge of liquid hydrocarbons, solid-phase carbon-containing products are formed, chemical transformations occur in the liquid phase and hydrogen-containing combustible gas is formed. Hydrogen-containing gas can be used as fuel immediately after synthesis, i.e. it does not require separation, since in addition to hydrogen it contains only impurities of CO₂ and water vapor. The purpose of the study is to formalize the basic conditions for tightening the control of mutual compliance with the efficiency of hydrogen engines of the same series in the conditions of their mass production. Methods of mathematical statistics and hardware-software modeling were used in the study. The term “unerroric of quality mutual compliance control” is introduced to describe a set of hardware and software tools for such control. The principle of in-depth testing of the technical condition of such engines of one series is described in a multidimensional formulation of the quality control problem for three of their operating parameters at once. The conditions for increasing the mutual correspondence of the measured values of such parameters in the conditions of serial production of hydrogen engines are formalized.

Constructal optimization of the geometry of an array of micro-channels

This paper documents the geometric optimization of an array of circular and non-circular ducts. The optimization was carried out numerically using finite volume method. As optimal dimensions were independent of the array configuration, the numerical simulation was performed on a unit cell. Numerical optimization for circular, square and isosceles right triangle cross-sections of channels was performed. Based on the results of this investigation, some correlations were proposed to predict the optimal hydraulic diameter and dimensionless heat transfer per unit volume. In addition to examining the effect of pressure drop on these parameters, it was showed that among the different geometries of this study, square cross-section has the most efficiency for a given volume. The numerical results of the present study were compared with approximate results reported in the literature which a good agreement was observed.

黄壁庄水库副坝塌陷机理分析

为了调查黄壁庄水库副坝频发塌陷事故的原因,从防渗墙槽壁稳定性角度研究了槽壁稳定性与护壁泥浆重度之间的关系,分析了第六次塌陷前的测试试验结果,并在多种因素共同作用下分析了黄壁庄水库副坝的塌陷机理。结果表明,由于护壁泥浆重度小于设计临界重度,使得槽壁失稳;同时泥浆水渗透到周围非饱和土层,引起土层地下水位上升,尤其是坝基下面的粉土层,在冲击成槽的施工振动、地下水位上升、含水率增加等多种因素的作用下逐渐液化,从而造成承载力降低;另外由于事先未发现基岩中存在溶洞,当成槽钻孔揭穿溶洞时,槽体内的护壁泥浆迅速下沉,槽壁的稳定急剧破坏,致使槽壁完全塌陷。     

某水库右坝段坝基渗漏特征及原因分析

针对中小型水库中的土石坝容易出现坝基、坝肩和绕坝渗漏的问题,分析了某水库右坝段渗漏部位及由此导致水库无法蓄水的具体原因。通过分析坝址区水位监测孔、钻孔取芯、压水试验、波速测井和钻孔全景成像等资料,发现该水库无法蓄水的最主要原因是坝基灌浆帷幕效果(透水率小于3Lu)未达到预期效果,基岩顶板渗透率很大,仍是主要的渗漏部位和通道,主要渗漏范围为灌浆盖板以下10m内,缘于未探明F3断层和三条张开度极大的卸荷裂隙情况,致使防渗处理存在缺陷。右岸山体基岩裂隙水的地下赋存与冻融对坝后渗漏通道的形成有一定促进作用,应该做出相应风险和灾害评估。研究成果可为类似工程提供参考。
