The description of nonstationary one-dimensional flow of a nonideal gas in a pipe is treated with the goal of developing a mathematical description of flow and pressure (density) dynamics adequate for creating a simulation model of large pipeline networks, the analysis starts from Newton's equation...
In this paper, a mathematical model that describes the flow of gas in a pipe is formulated. The model is simplified by making some assumptions. It is considered that the natural gas flowing in a long horizontal pipe, no heat source occurs inside the volume, transfer of heat due to heat ...
Several local controllers are used in the GCS to maintain pressures, temperatures, and flows at the specified levels, trying to reject the effects of disturbances, mainly caused by combined changes of input gas flow-rate and gas properties, like molecular weight, compressibility, and heat ratio. ...

Over the past decade, the significance of optimizing green supply chain management (GSCM) has gained unprecedented attention from both scholars and industry professionals. This surge in interest has led researchers to employ diverse modeling approaches in the pursuit of enhancing green supply chain netwo...
This is primarily due to the fact that the fluid flow and the heat transfer which influence the deposition process vary significantly from experiment to experiment. It is thought that Computational Fluid Dynamics with Chemistry (CFDC) models can be used to correlate the data obtained from a ...
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 ...
The algorithmic implementation of the metamodel provides one answer to modeling tool interoperability, which has the potential to create connections between static views of the system, for example, SysML block diagrams, and dynamics views of the system, such as Mathworks Simulink. In turn, this ...
