The nonlinear vibration behaviors of stiffened cylindrical shells under electromagnetic excitations, transverse and in-plane excitations are studied for the first time in this paper. Given first-order shear deformation theory Hamilton principle, partial differential governing equations motion derived with considering von Karman geometric nonlinearity. By employing Galerkin discretization proced...

This paper presents efflux time experiments performed in the absence and presence of aqueous solutions of Drag Reducing Agents (DRAs) when a liquid is emptied from a large open cylindrical storage tank through an exit piping system. The drag reducing agents studied are Dodecyl benzene sulfonate anionic surfactant and a mixed solution of surfactant and sodium chloride counter ion. The variab...
