The present numerical simulation investigates the time-dependent flow driven by the oscillatory pressure gradient in the streamwise direction.
An attempt was made to obtain the flow field that is initially stationary and evolves to the purely oscillatory flow with zero mean velocity, and the results after several cycles of oscillation are compared with the long-time analytical solution in the case where the flow domain is the space between the two infinitely large horizontal parallel plates. A round bump was added to the surface of the lower plate and the resulting flow field modified due to the protruding object was obtained. Additionally discussed is the temperature field due to the heat transfer through the bump.
