WebIn fluid dynamics, a stagnation point is a point in a flow field where the local velocity of the fluid is zero. The isentropic stagnation state is the state a flowing fluid would attain if it underwent a reversible adiabatic deceleration to zero velocity. There are both actual and the isentropic stagnation states for a typical gas or vapor. Sometimes it is advantageous to … WebMay 3, 2010 · First, we note that point A on the cylinder is a stagnation point in that no flow velocity can occur at this location. Since the streamline that passes through a stagnation point has a value of zero, the stream function on the entire surface of the cylinder of radius a should vanish, leading to the boundary condition ψ (a) = 0. WebMar 5, 2024 · The stagnation point can be seen from Figure 10.14 by ascertaining the location where the velocity is zero. Due to the symmetry the location is on "solid'' body on the x –coordinate at some distance from the origin.
