Abstract
We advance a method to estimate the carrier-flow dissipation in the presence of inertial sub-Kolmogorov particles at moderate . Its foundations rely on the unladen flow dissipation calculation using the Rice theorem, and the density of zero crossings of the longitudinal velocity fluctuation coming from a laser Doppler anemometry device. Our experimental results provide strong evidence regarding the non-negligible effect that sub-Kolmogorov particles have on the carrier-flow energy cascade at , and .
