A Cell vertex method for 3D invisdic internal flows

A viscous-inviscid interaction method for 2-D unsteady, compressible flows Tuncer, İsmail Hakkı; Platzer, Max F. (1993-01-01) © 1993 American Institute of Aeronautics and Aerodynamics, Inc. All rights reserved.A Navier-Stokes/potential flow interactive solution method suitable for the solution of steady-state and unsteady flowfields around airfoils has been developed. The Navier-Stokes equations are solved in the close proximity of an airfoil and in its wake. The inviscid flowfield surrounding the viscous flow regions is assumed to be irrotational and isentropic. In the inviscid flow region, the potential flow equations, which are...
A macroscopic model for self-organized aggregation in swarm robotic systems Soysal, Onur; Şahin, Erol (2006-10-01) We study the self-organized aggregation of a swarm of robots in a closed arena. We assume that the perceptual range of the robots are smaller than the size of the arena and the robots do not have information on the size of the swarm or the arena. Using a probabilistic aggregation behavior model inspired from studies of social insects, we propose a macroscopic model for predicting the final distribution of aggregates in terms of the parameters of the aggregation behavior, the arena size and the sensing chara...
A Fully Implicit Finite Volume Lattice Boltzmann Method for Turbulent Flow Cevik, Fatih; Albayrak, Kahraman (2017-08-01) Almost all schemes existed in the literature to solve the Lattice Boltzmann Equation like stream & collide, finite difference, finite element, finite volume schemes are explicit. However, it is known fact that implicit methods utilizes better stability and faster convergence compared to the explicit methods. In this paper, a method named herein as Implicit Finite Volume Lattice BoltzmannMethod (IFVLBM) for incompressible laminar and turbulent flows is proposed and it is applied to some 2D benchmark test cas...

A 2-0 navier-stokes solution method with overset moving grids Tuncer, İsmail Hakkı (1996-01-01) A simple, robust numerical algorithm to localize moving boundary points and to interpolate uniteady solution variables across 2-D, arbitrarily overset computational grids is presented. Overset grids are allowed to move in time relative to each other. The intergrid boundary points are localized in terms of three grid points on the donor grid by a directional search algorithm. The parameters of the search algorithm give the interpolation weights at the localized boundary point. The method is independent of nu...
