We consider surface-tension driven convection in a rotating fluid layer. For nearly insulating boundary conditions we derive a long-wave equation for the convection planform. Using a Galerkin method and direct numerical simulations we study the stability of the steady hexagonal patterns with respect to general side band instabilities. In the presence of rotation, steady and oscillatory instabil...

Leading-edge vortices that form at offdesign conditions can profoundly influence the aerodynamic characteristics of highly swept slender wings. predict wing geometry effects on the progressive spanwise development of leading-edge vortices is presented. This method, which can account for sweep, camber, twist, airfoil shape, flap deflections, and planform shape, is shown to be a useful tool for a...

The Brahmaputra River (BR) is a heavily braided river, due to various intricate paths, high discharge variability and bank erodibility, as well multi-channel features, which, in turn, cause huge energy dissipation. river also experiences anastomosing planform changes response seasonal water sediment waves, resulting morphology with extreme complexity. purpose of this study was provide detailed ...
