Abstract

Information obtained from multi-sensor probes which measure simultaneously the three velocity components and the instantaneous streamwise or transverse vorticity components was used to study coherent structures in low Reynolds number turbulent channel flows. The data permitted the evaluation of terms in the equation of the mean- square vorticity fluctuations. A quadrant splitting of the instantaneous Reynolds stress signals allowed a connection between vorticity and turbulent kinetic energy producing events.
