Airplane Vortices Evolution Near Ground

Applied Sciences, 2021
Airport traffic around the world has sharply increased over the years; as a result, airports need to be enlarged and the landing or taking off times between two consecutive airplanes must be reduced.

Capytaine: a Python-based linear potential flow solver

Journal of Open Source Software, 2019
Assuming an incompressible, inviscid and irrotational flow, the fluid motion can be modeled by a scalar field φ, called velocity potential and such that u = ∇φ.

Variational water-wave model with accurate dispersion and vertical vorticity [PDF]

, 2009
A new water-wave model has been derived which is based on variational techniques and combines a depth-averaged vertical (component of) vorticity with depth-dependent potential flow. The model facilitates the further restriction of the vertical profile of

A parallel interaction potential approach coupled with the immersed boundary method for fully resolved simulations of deformable interfaces and membranes [PDF]

, 2016
In this paper we show and discuss the use of a versatile interaction potential approach coupled with an immersed boundary method to simulate a variety of flows involving deformable bodies.

Kaon differential flow in relativistic heavy-ion collisions [PDF]

, 1999
Using a relativistic transport model, we study the azimuthal momentum asymmetry of kaons with fixed transverse momentum, i.e., the differential flow, in heavy-ion collisions at beam momentum of 6 GeV/c per nucleon, available from the Alternating Gradient

The impact of the Dirichlet boundary conditions on the convergence of the discretized system of nonlinear equations for potential problems

Computer Assisted Methods in Engineering and Science, 2017
The purpose of this paper is the analysis of numerical approaches obtained by describing the Dirichlet boundary conditions on different connected components of the computational domain boundary for potential flow, provided that the domain is a rectangle.

Mixed-Fidelity Design Optimization of Hull Form Using CFD and Potential Flow Solvers

Journal of Marine Science and Engineering, 2021
The present paper proposes a new mixed-fidelity method to optimize the shape of ships using genetic algorithms (GA) and potential flow codes to evaluate the hydrodynamics of variant hull forms, enhanced by a surrogate model based on an Artificial Neural ...

``Superfast'' Reaction in Turbulent Flow with Potential Disorder

, 1998
We explore the regime of ``superfast'' reactivity that has been predicted to occur in turbulent flow in the presence of potential disorder. Computer simulation studies confirm qualitative features of the previous renormalization group predictions, which ...

Increase of the Ship Fuel Consumption Due to Added Resistance in Waves

Journal of Sustainable Development of Energy, Water and Environment Systems, 2017
Added resistance in waves is the second-order steady force dependant on the ship motions. It significantly affects ship operability and cause speed loss. Therefore the required power and fuel consumption of a ship advancing in a seaway are increasing. In
