The pattern selection problem in binary-mixture convection in an extendedchannel with a lateral through-flow is presented. The through-flow breaksleft--right parity and changes pattern dynamics dramatically. The problem isstudied based on computer simulation of the complete set of hydrodynamicequations (Oberbeck-Boussinesq approximation) in the two-dimensionalrectangular channel with aspect ratio $\Gamma = 12$ and convection-suppressinglateral boundary conditions. A wide variety of new dynamical patterns isobtained, discussed and classified.Comment: 9 pages and 2 figure
