Near-field flow structures and transient growth due to subcritical surface roughness

Near-field flow structures and transient growth due to subcritical surface roughness

An immersed boundary spectral method is used to simulate laminar boundary layer flow over a periodic array of cylindrical surface roughness elements. Direct comparisons are made with experiments by using a roughness-based Reynolds number Re[subscript k] of 216 and a diameter to spanwise spacing rati...
