AbstractThe modification of turbulence due to the introduction of dilute fibres in a channel flow is analysed by means of Direct Numerical Simulation (DNS). Using a simplified rheological model it is possible to assess that the modification of turbulent structure is far simpler than in the flexible case. In fact, at a given fibre concentration some relevant, statistics show a substantial insensitivity on Reynolds number.
