FLOW-3D Analysis on Scouring around Offshore Wind Foundation [PDF]

Journal of the Korea Academia-Industrial cooperation Society, 2012
In order to evaluate the local scour around offsshore wind foundation, mono pile and jacket foundation were simulated by using FLOW-3D. Numerical analysis results show that local increases of velocity around mono pile and jacket foundation was developed but velocity decreases in backward of pile and leg due to the wake vortex was observed.

Ship resistance analysis using CFD simulations in Flow-3D

The International Journal of Multiphysics, 2020
While designing the power requirements of a ship, the most important factor to be considered is the ship resistance, or the sea drag forces acting on the ship. It is important to have an estimate of the ship resistance while designing the propulsion system since the power required to overcome the sea drag forces contribute to ‘losses’ in the propulsion

The Numerical Investigation on Vortex Flow Behavior Using FLOW-3D

Iranica Journal of Energy & Environment, 2012
In this paper a numerical investigation is given for a Rankine type vortex flow inside the cylindrical vortex chamber using FLOW-3D. The FLOW-3D is a general purpose computational fluid dynamics (CFD) package. The fluid motion is described with non-linear, transient, second-order differential equations. Additionally the free surface also exists in many

The simulation of the buoy for oscillating wave energy converter with Flow 3D [PDF]

Proceedings of the 2016 5th International Conference on Environment, Materials, Chemistry and Power Electronics, 2016
In order to ensure energy collecting efficiency of oscillating wave energy converter in the actual application of Donggang's sea area in China, Flow 3D software is used to simulate hydrodynamic performance of different shape of the buoy. The result is : The average mass center z coordinates of the butterfly cylinder is higher than the hollow cylinder ...

Flow Characteristics Investigation On Trapezoidal Weir Using FLOW 3D

IOP Conference Series: Earth and Environmental Science, 2022
Abstract Weir is a building that is formed to change the nature of river flow to accommodate irrigation needs. The main purpose of a weir is to raise the river water level, drain the channel through the intake channel, allow water to be tapped, control all flow, etc.

شبیه سازی عددی تاثیر همگرایی دیواره ‌های شوت بر شکل‌گیری امواج عرضی در سیستم‌های تخلیه سیلاب [PDF]

هیدرولیک, 2019
برخورد جریان با پایه‌های روی سرریز باعث شکل‌گیری امواج دم خروسی و توسعه امواج عرضی در طول سیستم تخلیه سیلاب می‌شود. ازاین‌رو دستیابی به اطلاعات مربوط به ارتفاع و محل تشکیل این امواج در طراحی دیواره‌های سرریز بسیار پرکاربرد می‌باشد.
