Flow around a wing construction at medium Reynolds number (variable angle of attack)

Flow around a wing construction with time dependent angle of attack. Up to T=4 the angle of attack is 4.5 degree, changing up to 27 degrees until T=6, staying constant until T=10, going down to 4.5 degrees again until T=12 and preserving this constant value. Consequently, this configuration describes the "starting phase of an aircraft" (in a very qualitative manner) with different angles of attack until the "final height" is reached. This simulation has to be compared with the similar ones in the Album, including lower/higher Reynolds numbers and different angles of attack.
