The optimization of the water-entry strategy for cross-wing underwater vehicles has become a research hotspot in field engineering, and its process is quite different from that wedges cylinders. In order to address this problem, numerical model vehicle was first established based on CFD method. governing equations boundary conditions dynamic were defined, along with basic principles discretization turbulent flow equations. overset mesh VOF multiphase introduced, size independence analysis...
A complicated coupling system performs fuel filling operation of a ship on the sea that involves tank sloshing and impact. This research elaborated load flow characteristics variable mass revealed its physical process through numerical simulations to provide safety assurance for filling. First, this work clarified difference between theory ordinary sloshing. On foundation, model was developed three-dimensional In addition, validated by comparing results previous experiments. Second, pressure...
Fresh blueberries were selected as trial materials. Two blueberry juice samples sterilized using pulsed electric field and thermal treatments respectively. Their qualities analyzed compared by evaluating the microorganisms in samples. The changes quality of fresh during storage also assessed. results showed that inactivation Escherichia coli increased strength treatment time increased. Pulsed at 35 kV/cm 82 μs reduced E. 5.12 logarithms. had less effect on quality, but after heat treatment,...
Abstract Balancing optical modulation and response time is crucial for achieving high coloration efficiency in electrochromic materials. Here, internal electric fields are introduced to titanium dioxide nanosheets by constructing abundant amorphous‐crystalline interfaces, ensuring large while reducing therefore improving efficiency. Aberration‐corrected high‐angle annular dark‐field scanning transmission electron microscopy (HAADF‐STEM) reveals the presence of numerous phase boundaries...
An improved insight into the effect of powdered activated carbon (PAC) on membrane fouling is crucial to MBR performance. Sludge key property, soluble microbial products (SMP) and transmembrane pressure (TMP) were monitored. The rate in MBRs was also analyzed based TMP profile resistance-in-series model. PAC reduced filtration resistance significantly decreased rate. sludge filterability by extending time almost twofold. affected SMP release protein/polysaccharide (carbohydrate) a lower...
In the system of PV grid-connected generation, because dispersion panel, difference sun radiation condition and shadow a part they will cause serious loss energy for parallel panel. order to overcoming raise efficiency system, new maximum power point tracking method called distributed variable step duty ratio perturb is put forward. The MPPT overcomes shortcomings generate electricity quantity descend perturbing speed quickly more suitable this kind generation system. hardware adopts DC/DC...
The urban atmospheric boundary layer (UABL) is complex due to the heterogeneous underlying city surface. nine anemometers installed at different heights along 325 m meteorological tower provide an opportunity carry out a refined study of wind properties in UABL central Beijing, China. Based on recent 5-year high-resolution measured data, total, 229,488 10-min length segments records related each anemometer are reliable for further analyses. Accordingly, statistical speed and direction first...
Extreme wind, thunderstorm, occurs throughout the world, even in polar regions. At any given time approximately 2,000 thunderstorms are occurring on Earth. Many structural damages induced by them have been recorded around world. Study of thunderstorm outflows and their effects structures already becomes a key topic modern wind engineering. This paper analysed main properties typical outflow event occurred Beijing based measured data detected 9 ultrasonic anemometers mounted 325 m high...
Abstract In response to the gradually stringent carbon emission requirements of International Maritime Organization (IMO), energy-saving methods shipping industry have received increasing attention. Today how reduce fuel consumptions so as lower emissions improve economic and environmental benefits ships has become a hot topic. As one most easily implemented methods, trim optimization caught more researchers’ eyes. this paper, commercial CFD software STAR-CCM+ was adopted analyze influence...
Accurate prediction about the penetration depth of moving targets is vital for deep-sea target detection. Moving penetrating into seafloor sediment always produce large deformation, Arbitrary Lagrangian-Eulerian (ALE) technique has better grid adaptability and it can solve mesh distortion generated by sediment. Therefore, in present work, investigations on targets’ are conducted based ALE technique. The physical process simulated using Results compared with empirical results experimental to...

As the second largest cause of death in human beings only behind cancer, sudden cardiac (SCD - Sudden Cardiac Death) is featured as onset and difficult to rescue. Therefore, for these patients, early diagnosis, intervention most effective treatment. TWA (T wave alternans) detection SCD-like illness an important indicator. How obtain accurate data a research focused on recent years. This paper presents Kalman filter-based (non-steady state) algorithm. Firstly, we preprocess, denose baseline...
