Application of Moving Adaptive Meshes in Hyperbolic Problems of Gas Dynamics
نویسنده
چکیده
It is well known that if the solution of flow equations has regions of high spatial activity, a standard fixed mesh technique is ineffective, since it should contain a very large number of mesh points. In case of hyperbolic problems of gas dynamics there are domains containing shock waves and contact discontinuities. A moving mesh adaptation algorithm is applied to reduce computational costs in practical modeling. In such an approach the grid nodes are relocated so that to increase mesh concentration in the domains of steep moving fronts, emerging steep layers, pulses and shock waves.

An Adaptive-Robust Control Approach for Trajectory Tracking of two 5 DOF Cooperating Robot Manipulators Moving a Rigid Payload
In this paper, a dual system consisting of two 5 DOF (RRRRR) robot manipulators is considered as a cooperative robotic system used to manipulate a rigid payload on a desired trajectory between two desired initial and end positions/orientations. The forward and inverse kinematic problems are first solved for the dual arm system. Then, dynamics of the system and the relations between forces/momen...
متن کاملAdaptivity with moving grids
In this article we describe the basic dynamics of a moving meshes as part of an r-adaptive adaptive method. We firstly examine the possible geometry of a moving mesh and strategies for disretising a partial differential equation on such a mesh. We then look in more detail (with many examples) at strategies for implementing both position based and velocity based moving meshes. We finally look at...
متن کاملThe comparison of two high-order semi-discrete central schemes for solving hyperbolic conservation laws
This work presents two high-order, semi-discrete, central-upwind schemes for computing approximate solutions of 1D systems of conservation laws. We propose a central weighted essentially non-oscillatory (CWENO) reconstruction, also we apply a fourth-order reconstruction proposed by Peer et al., and afterwards, we combine these reconstructions with a semi-discrete central-upwind numerical flux ...
متن کاملA robust moving mesh finite volume method applied to 1D hyperbolic conservation laws from magnetohydrodynamics
In this paper we describe a one-dimensional adaptive moving mesh method and its application to hyperbolic conservation laws from magnetohydrodynamics (MHD). The method is robust, because it employs automatic control of mesh adaptation when a new model is considered, without manually-set parameters. Adaptive meshes are a common tool for increasing the accuracy and reducing computational costs wh...
متن کاملEffect of Nondimensional Parameters On the Internal Circulation of a Liquid Drop Moving with the Surrounding Gas
The internal flow circulation dynamics of a liquid drop moving in a co- or counter-flowing gas stream has been numerically studied. The present work is concerned with the time accurate numerical solution of the two phase flow field at the low Mach number limit with an appropriate volume tracking method to capture motion and deformation of a liquid drop. It is shown that relative velocity betwee...
