Abstract: It is shown that periodic angular oscillations can be forced on a jet issuing from a nozzle based on the Coanda effect by alternate blowing from the two sides. The influence of the various ...

Abstract: Numerical modeling and analytical approach were used to compute laminar flows in rough-wall microchannels. Both models considered the same arrangements of rectangular prism rough elements in ...

Abstract: The turbulent flow close to a wall with two-dimensional roughness is computed with a two-layer zonal model. For an impermeable wall, the classical logarithmic law compares well with the numerical ...
