Transient response of Reynolds stress transport to opposition control in turbulent channel flow

摘要：

The mechanism for turbulence suppression by opposition control developed by Choi is studied via the analysis of Reynolds stress transport in the initial period of control. It is found that the pressure-strain and pressure-diffusion terms first break up the balance in vertical normal Reynolds stress transport, and result in the final global suppression of turbulence intensities. The transient growth in spanwise normal Reynolds stress is also caused by the pressure-strain term.
