Abstract: Growth dynamics and spatiotemporal evolutions of one-dimensional tra veling-wave pattern in a binary-fiuid-mixture Reylaigh-Benard convection with extremely weak through-flows are investigated by numerically simulating basic hydr odynamic equations. We show that the system exhibits repeated dynamics of trave lingwave convection, and their repeating periods depend sensitively on the strength of through-flow。
Keywords:
