Modeling of slug dissipation and generation in gas-liquid hilly-terrain pipe flowFlow (DynamicsEnergy dissipationSlugPipe flowHilly-terrain pipelines consist of interconnected horizontal, uphill and downhill sections. Slug flow experiences a transition from one state to another as the pipe inclination ...
This research work investigates the dynamics characteristics of the offshore riser pipeline due to vortex flow and to develop a model that could predict its vortex induced responses. A riser made of Glass-fiber Reinforced Plastic (GRP) is used for this study. The mathematical model is derived ...
We survey operational models of water-distribution systems. Although such modeling is important in its own right, our focus is motivated by the growing des
积尘颗粒数难以在现实中测定,故常采用计算流体力学模式(Computational Fluids Dynamics, CFD)仿真分析沉降率(Lu et al., 2016; Lu and Zhao, 2019; Dagher and Kandil, 2022; Fan et al., 2022; Peng et al., 2022)。轨迹分析结果显示,在某一确定风速下,在粒径增加时许多颗粒物脱离气流沉降到光伏组件表面...
Pressure and flow rate along the network over time. The location and progression of the liquid slug through the system. Has anyone modeled something similar using Simscape Fluids? I’m not sure how to represent the slug dynamics and the two-phase interaction in this geometry...
(cf. Table2). For prediction and impact assessment, AI models are sensitive to initial conditions and may not capture long-term dependencies91. Moreover, data might not reveal the dynamics of extremes, as there might be changes to unseen dynamics23and stationarity may not hold in general. ...
A description of classical mathematical models describing gas dynamics can be found in [5]. Today, aided by modern, powerful computers, the numerical modeling of gas pipeline networks can be highly accurate. The development of technologies and numerical methods opens opportunities for the development ...
In addition to the aforementioned methods, nonlinear control is frequently employed in managing the gas supply system of PEMFC, yielding notable achievements. For this strongly nonlinear system, the dynamics are far more complex than for a linear system. It is obvious that a linearized model to po...
2.1 Modeling of time-coupling energy storage Energy storage is used to store a product in a specific time step and withdraw it at a later time step. Hence, energy storage couples the time steps in an optimization problem. Modeling energy storage in stochastic optimization increases complexity. In...
