A new fully-implicit approach for computing transonic aeroelastic solutions is presented. The unsteady Euler equations are coupled with a typical section swept wing model and integrated forward in time. The implicit Euler equations are integrated in pseudo-time using multigrid methods, and are coupled with a first-order system decomposition of the structural modal equations. Full convergence of...

Particle image velocimetry (PIV) is used to measure the instantaneous two-dimensional velocity field in turbulent, planar mixing layers at varying levels of compressibility. The structure of the instantaneous velocity and vorticity fields are seen to display similar variation with compressibility as the scalar field, with the spatial intermittency of the velocity field tied to the interfaces of...

introduction: studying the hydrological cycle, especially in large scales such as water catchments, is difficult and complicated despite the fact that the numbers of hydrological components are limited. this complexity rises from complex interactions between hydrological components and environment. recognition, determination and modeling of all interactive processes are needed to address this i...

A natural reach of montane stream (length 96 m and 7 m width) was grided into 150 cells (2 × 2 m). Density and biomass of fish (Salmo trutta L. and Cottus poecilopus Heckel) were estimated at each cell, as well as stream depth, current velocity, Froude number, bed granulation and its roughness were measured, and benthic samples from exposed bricks were collected from mid August to early October...
