Numerical Analysis of Resistance Characteristics of a Novel High-Speed Quadramaran

open access: yesPolish Maritime Research, 2023
This paper utilised computational fluid dynamics (CFD) technology to calculate the resistance of a novel high-speed quadramaran in calm water using the Navier‒Stokes (N‒S) equation, analysed the total resistance, frictional resistance, and residual ...

Traffic of multi-car trains in marshalling yards [PDF]

open access: yesE3S Web of Conferences, 2023
Developing rail transport is one of the world's greatest challenges. Rail transport reduces emissions and is the most energy efficient means of transport. An important element of the railways is a hump yard, where rolling stock is formed.

Analysis of the movement of an empty car on the longitudinal profile of the hill [PDF]

open access: yesE3S Web of Conferences, 2023
At present, in the existing methods for determining the height of a hump, the height is calculated based on the most difficult conditions - winter temperature and head wind, and a four-axle empty covered wagon is selected for a poor runner.

Updating the numerical characteristics of main resistance to wagon movement when rolling down a hump [PDF]

open access: yesE3S Web of Conferences, 2023
The parameters for humps are designed by the results of the roll-down of wagons with the design running performance. The numerical characteristics of the main specific resistance forces to the movement of wagons currently used in hump design are given in

RANS CFD Analysis of Hump Formation Mechanism in Double-Suction Centrifugal Pump under Part Load Condition

open access: yesEnergies, 2021
The RANS (Reynolds-averaged Navier–Stokes equations) with CFD (Computational Fluid Dynamics) simulation method is used to analyze the head hump formation mechanism in the double-suction centrifugal pump under a part load condition.

The impacts of neighbourhood traffic management [PDF]

open access: yes, 2012
A major traffic-related problem faced by residents is speeding, which not only causes safety concerns, but also noise issues. Traffic calming is a much favoured traffic management tool employed by road controlling authorities to primarily reduce ...

Traffic flow parameters development modelling at traffic calming measures located on arterial roads

open access: yesAin Shams Engineering Journal, 2021
Controlling the speed of vehicles is essential in some parts of the roadway. One way of controlling speed is to use static control devices i.e. traffic calming measures, which reduce the speeds of vehicles and thereby increase safety, while produce ...
