I understood the second sentence. It says that the vortex decreases the flow velocity. But I am not able to interpret the first one. When a vortex or some body blocks the flow does that mean the flow reverses it's direction i.e., if the flow is occurring say along the positive x direction, if the flow is blocked, does it start to flow along the negative x direction? What is the difference between these two sentences? Last edited by Giri_24; April 7, 2020 at 23:50.
