Relaxation of the resistive superconducting state in boron-doped diamond films

We report a study of the relaxation time of the restoration of the resistive superconducting state in single crystalline boron-doped diamond using amplitude-modulated absorption of (sub-)THz radiation (AMAR). The films grown on an insulating diamond substrate have a low carrier density of about 2.5×1021cm?3 and a critical temperature of about 2K...

Large Eddy Simulation of the flow around a wind turbine blade

Large Eddy Simulations (LES) of incompressible turbulent flow around a wind turbine blade at a chord Reynolds number of 5000 are performed using high-order spectral/hp element method (SEM). The method and the early results of the simulations are presented. Some requirements with respect to mesh generation for the SEM concerning h- and p...

Direct numerical simulation of the turbulent flow around an airfoil using spectral/HP method

Since the accuracy of the widely used Reynolds Averaged Navier Stokes (RANS) approach is limited simulating turbulent flow separation on airfoils, we applied a spectral/hp element method to predict the turbulent flow separation at an airfoil for an angle of attack of 12°. The spectral/hp approach allows to solve the incompressible Navier-Stokes...
