In the present work, laminar–turbulent transition of flow evolving around a low-pressure turbine blade has been investigated. Direct numerical simulations have carried out for two different free stream turbulence intensity (FSTI) levels to investigate role oscillations on evolution boundary layer. Emphasis is placed identifying mechanisms driving formation and breakup coherent structures in hig...

We discuss the stability of icosadeltahedral shells subjected to a uniform external load in the form of an isotropic pressure. We demonstrate that there exists a universal critical buckling pressure scaling form that defines a locus of buckling instabilities. The parameter that uniquely determines this scaling form is shown to be the Föppl-von Karman number of nonpressurized shells. Numerical r...
