Numerical simulation of a Richtmyer–Meshkov instability with an adaptive central-upwind sixth-order WENO scheme
Two-dimensional simulations of the single-mode Richtmyer–Meshkov instability (RMI) are conducted and compared to experimental results of Jacobs and Krivets (2005 Phys. Fluids 17 034105). The employed adaptive central-upwind sixth-order weighted essentially non-oscillatory (WENO) scheme (Hu X Y et al 2010 J. Comput. Phys. 229 8952–65) introduces only very small numerical dissipation while preser...
متن کاملLarge-eddy simulation and multiscale modelling of a RichtmyerMeshkov instability with reshock
Large-eddy simulations of the Richtmyer–Meshkov instability with reshock are presented and the results are compared with experiments. Several configurations of shocks initially travelling from light (air) to heavy (sulfur hexafluoride, SF6) have been simulated to match previous experiments and good agreement is found in the growth rates of the turbulent mixing zone (TMZ). The stretched-vortex s...
متن کاملCurrent-Mode Sixth-Order Elliptic Band-Pass Filter Using MCDTAs
In this paper, a modified CDTA(MCDTA) is presented and the current-mode second-order band-pass, high-pass notch, and low-pass notch circuits using MCDTAs are given. Moreover, a current-mode sixth-order elliptic band-pass filter is realized by means of cascade method. Having used six MCDTAs, one CDTA, six grounded capacitors and two resistors, the circuit is easy to be integrated, of which the p...
متن کاملPerformance of High Order Filter Methods for a Richtmyer-Meshkov Instability
Sixth-order compact and non-compact filter schemes that were designed for multiscale Navier-Stokes, and ideal and non-ideal magnetohydrodynamics (MHD) systems are employed to simulate a 2-D Rightmyer-Meshkov instability (RMI). The suppression of this RMI in the presence of a magnetic field was investigated by Samtaney (2003) and Wheatley et al. (2005). Numerical results illustrated here exhibit...
متن کاملExact Solutions for the Integrable Sixth-Order Drinfeld-Sokolov-Satsuma-Hirota System by the Analytical Methods
We establish exact solutions including periodic wave and solitary wave solutions for the integrable sixth-order Drinfeld-Sokolov-Satsuma-Hirota system. We employ this system by using a generalized (G'/G)-expansion and the generalized tanh-coth methods. These methods are developed for searching exact travelling wave solutions of nonlinear partial differential equations. It is shown that these me...
