A method is proposed to investigate the steady deformation and the drag of a single droplet in a flowing gas at a high Reynolds number.The volume of fluid(VOF)method is used to model the droplet surface structure.The direct numerical simulation(DNS)method
文章以枣庄市市中区东沙河东各埠橡胶坝为例,结合工程实际,介绍了TPEP管道应用的设计要点、施工技术,为今后在具有一定腐蚀性水环境中的橡胶坝工程建设提供借鉴。
通过对转炉生产工艺进行优化,采取滑板挡渣技术,脱氧合金化优化路线:出钢1/3开始加入硅铁、硅锰合金、渣洗剂,吹氩站喂铝线操作,碳钢酸溶铝控制在0.008%~0.01%,低碳低硅钢酸溶铝控制在0.015%~0.054%,吹氩站吹氩12~15 min,连铸全程保护浇铸等措施。钢水洁净度得到明显提升,脱氧剂消耗由原来的3.17 kg/t钢降至1.549 kg/t钢,实现效益10.88元/t钢。
In this paper, the flow field around NACA0015 hydrofoil is calculated under the condition of two-phase cavitating flow to provide a theoretical guidance for red
By impacting a concave dual-layer liquid(with the oil and the dyed water)surface in a test tube,a compound jet with a water core and an oil shell is generated.T
Vortical structures and wakes of bluff bodies in homogenous and stratified environment are common and important in ocean engineering.Based on the Boussinesq app
文章通过南水北调东线山东境内明渠段渠道工程地温监测成果的分析,总结了采取蓄水保温措施对防止衬砌渠道冻胀破坏的效果,并结合地温监测对渠道衬砌工程设计、施工及运行管理提出了建议,可为类似工程建设与运行管理提供参考。
Droplet breakage is a common phenomenon in converting a pipe flow to a swirl flow in a vane-type pipe separator (VTPS)' inlet. The evaluation of the dispersed d
The suspended sediment transport capacity is important for estimating the suspended load concentration and the ecological environment of the river.So far,few studies have been conducted to investigate the suspended sediment transport capacity in the veget
A new approach referred as “the network modeling method” was developed by the authors to analyze the behaviors of marine structures. In this paper the method
