What is Measurement of Fluid Turbulence Along the Path of a Heavy Particle in a Backward-facing Step Flow about?
To accurately model the motion of a solid particle in a turbulent air ̄ow, characteristics of the ̄uid turbulence in the particle-Lagrangian reference frame must be known. This paper describes a quasi-numerical technique that uses a laser Doppler anemometer (LDA) probe mounted on a two-dimensional traverse to track the path of an emulated particle through a turbulent backward-facing step ̄ow. Fluid velocity measurements (from the LDA) are inputs to a control loop that accelerates the LDA probe as if it were a particle allowing for particle-Lagrangian ̄uid statistics to be measured. Particles with time constants from 0.1 to 10 s were run through a backward-facing step ̄ow with Reynolds number 10,000 based on step height and inlet velocity. Digital particle image velocimetry (DPIV) was used to estimate the ̄uid vorticity along the particle path. The results show that the particle behavior is a strong function of particle path. Particles entering the shear layer see a larger range of turbulence and therefore are more aected by the ̄ow than those that stay outside the shear layer.
