VORLAX 2020: Making a Potential Flow Solver Great Again

AIAA AVIATION 2021 FORUM, 2021
VORLAX is a vortex-lattice potential flow solver written by Luis R. Miranda for Lockheed California in the early 1970’s. While the tool has remained a viable solution for resolving shock-free flow conditions on a wetted surface, many aspects of the code ...

Ecosystem service potential, flow, demand and their spatial associations: a comparison of the nutrient retention service between a human- and a nature-dominated watershed.

Science of the Total Environment, 2020
Nutrient regulation is an important ecosystem regulating service in watersheds. However, systematic investigations of the spatial associations between the potential, flow, and demand of the nutrient regulation service are still lacking.

REEF3D::FNPF—A Flexible Fully Nonlinear Potential Flow Solver

, 2020
In situations where the calculation of ocean wave propagation and impact on structures are required, fast numerical solvers are desired in order to find relevant wave events.

Isogeometric boundary element analysis of problems in potential flow

Computer Methods in Applied Mechanics and Engineering, 2019
The aim of the paper is to show that the isogeometric Boundary Element Method (isoBEM) has advantages over other numerical methods when applied to problems in potential flow.

A potential flow model with viscous dissipation based on a modified boundary element method

Engineering analysis with boundary elements, 2018
Conventional potential flow models are known to exaggerate predictions in water wave resonance problems, attributed to the inviscid fluid assumption in the potential theory.

On the Coupling of Incompressible SPH with a Finite Element Potential Flow Solver for Nonlinear Free-Surface Flows

International Journal of Offshore and Polar Engineering, 2018
This paper presents a two-dimensional, one-way coupling methodology between the quasi-arbitrary Lagrange–Euler finite element method (QALE-FEM) nonlinear potential flow solver and the incompressible smoothed particle hydrodynamics (ISPH) Navier-Stokes ...

Potential flow

2001
Abstract The study of an ideal (perfect) fluid-’dry water’, as Richard P Feynman refers to it in the Feynman Lectures in Physics-is a crucial part of fluid dynamics. In the mechanics of solids, the laws of motion can be expressed, in the absence of friction, in terms of conservation laws.

Convexity of Self-Similar Transonic Shocks and Free Boundaries for the Euler Equations for Potential Flow

Archive for Rational Mechanics and Analysis, 2018
We are concerned with geometric properties of transonic shocks as free boundaries in two-dimensional self-similar coordinates for compressible fluid flows, which are not only important for the understanding of geometric structure and stability of fluid ...

Flows, Hierarchies, Potentials

Environment and Planning A: Economy and Space, 1981
This work deals with the analysis of interregional flows. The central idea is the decomposition of the origin–destination flow matrix into the additive weighted sum of basic matrices. Each basic matrix represents an extremal flow which optimizes some objective function corresponding to some extremal tendency acting in the real flow.
