Michelson sivashinsky equation
WebIn this paper we present a numerical technique for solving Kuramoto-Sivashinsky equation, based on spectral Fourier methods. This equation describes reaction diffusion problems, and the dynamics of viscous-fuid films flowing along walls. After we wrote the equation in Fourier space, we get a system. WebEquation (1.5) is called the Michelson-Sivashinsky (MS) equation. It is a refined combustion model based on the Darrieus–Landau flame stability analysis, and was also recently derived in [26, 42]. Several computational studies were performed on the periodic one-dimensional version of (1.5), see for instance
