Flow through the spiral casing of a hydraulic turbine was analyzed. Reynolds averaged Navier -Stokes equations were solved using a finite element method. The physical domain was divided into a number of hexahedral elements which are isoparametrically mapped onto standard cubic elements. Numerical in
## Abstract Twoβdimensional turbulent diffusion is modeled with a generalized Langevin equation. Instantaneous velocities are simulated by using white noise filtered to simulate turbulence. By generating fluctuating signals that are partially correlated, it is possible to model diffusion for a turb
