Hybrid electric vehicles (HEVs) combined with more than one power source offer additional flexibility to improve the fuel economy and reduce pollutant emissions. The dynamic-programming-based supervisory controller (DPSC) presented here investigates improvement emissions reduction potential demonstrates trade-off between emission of nitrogen oxides (NO x ) for a state-of-charge-sustaining parallel HEV. A weighted cost function consisting is proposed in this paper. Any possible engine-motor...
Abstract The Du 84 block of the Shu-1 area in Liaohe Oil Field is located Panjin City, Liaoning Province, China. production formation, Guantao, contains extra heavy oil with a depth 530–640 m. reservoir characterized thick pay, high permeability and very active aquifer. dead viscosity 230,000 mPa.s at 50 °C. Although Cyclic Steam Stimulation (CSS) process using vertical wells has been applied successfully producing from reservoir, anticipated ultimate recovery less than 29% original place...
Electric multiple unit is a modern transportation tool with high efficiency and large carrying capacity. Regarding its speed, reliability requirement of the train very important. As main load bearing component train, wheel subjected to harsh working condition. Rolling contact between rail leads fatigue failure so that becomes one most attractive fields in electric study. This article proposed assessment method. It could obtain critical parts’ stress distribution efficiently through...
Purpose The purpose of this paper is to develop a novel method for analyzing wheel-rail (W-R) contact using thermo-mechanical measurements and study the effects heating on characteristics W-R under different creepages. Design/methodology/approach This developed an implicit-explicit finite element (FE) model which could solve both partial slip full sliding problems by setting angular velocities wheels. Based model, four material types six creepages were simulated. Findings results showed that...
As an important basis for determining the state of liver, mechanical responses are associated with many factors, and belong to a complex coupling system. Liver tissue has significantly complicated vascular channels. The diameter, deflection angle depth defined as key characteristic parameters. influences these parameters on were analyzed. On real parameters, coupled numerical model blood vessel, flow liver was established. corresponding obtained by utilizing different effects differences...
Icing on transmission lines often causes potential electric damage in power systems. Superhydrophobic anodized Al conductors have been proposed to good anti-icing properties. In this study, superhydrophobic with composite nanopore structures were prepared by a two-step anodization. The microstructure, hydrophobicity, and properties of compared studied. optimal preparation parameter was determined as current density 0.04375 A/cm2 anodization time 15 min. Compared the bare substrate, surface...
Abstract The freezing of water droplets greatly harms overhead conductors and other outdoor infrastructures. Superhydrophobic (SHP) surfaces are an effective practical method preventing ice. SHP rapidly repel the impact before freezing. Herein, with a high aspect ratio narrow gap nanostructures were prepared on aluminum plates by anodic oxidation, influences temperature speed bounce behaviors systematically studied. drop in delays escape liquid surface reduces bouncing height. Notably, still...
The icing on transmission lines seriously threatens the safe operation of power system. Liquid-infused surfaces (LIS) shows a great potential in anti-icing field due to its extremely low ice-adhesion strength. Herein, freezing time, frost morphology, performance under glaze ice, and durability LIS were systematically studied. 1061 aluminum, same material as aluminum conductors, was selected substrate. porous surface prepared by anodic oxidation, infusing silicone oil into structure. time at...
