Figure 11.
The image depicts a multi-panel graph showing V x in metres per second at 2, 3, 4, and 8 seconds. Each panel presents flow past a circular cylinder positioned at the left boundary of a channel. The colour bar at the top is labelled V x in metres per second with values from negative 1.6 multiplied by 10 to the power 0 to 4.6 multiplied by 10 to the power 0. Streamlines and velocity vectors illustrate vortex shedding behind the cylinder, forming alternating wake structures that extend downstream along the channel at each specified time.Newtonian fluid showing the formation of a Kármán vortex street due to strengthened wake instabilities
