please i want to simulate the experience of snyder and lumley1971 (Some measurements of particle velocity autocorrelation functions in a turbulent flow) with fluent 2d


but the problem that i don't now how to define the grid so that the flow became turbulent
the inlet velocity is 6.55 m/s length : 4 m width:0.46 m

so in the result the flow is laminar and the velocity reste constant along the trajectory

i need to perturbe the velocity from the inlet . in the experience they use a grid to generate the turbulence

please someone help me

thanks i have make a mistake the article is 'Some measurements of particle velocity autocorrelation functions in a turbulent flow'

and the two figures is an exemple of the experience.
