Web12 Mar 2024 · A small jet aircraft, designed to cruise at Mach 3.5, has a variable area supersonic diffuser. If the shock is swallowed at this Mach number, find the ratio of the throat area for shock-free diffuser to the throat area at which shock is swallowed. Exercise 6.8. A uniform airstream at Mach 2.5 flows through a convergent flow passage. Web21 May 2024 · Normal shock waves form on the wing’s upper surface and form an additional area of supersonic flow and a normal shock wave on the lower surface. As flight speed approaches the speed of sound, the areas of supersonic flow enlarge and the shock waves move nearer the trailing edge. Shock waves. Associated with “drag rise” are buffet (known ...
Web1 Oct 2004 · Although multiple regions of the cerebral cortex have been implicated in swallowing, the functional contributions of each brain area remain unclear. The present study sought to clarify the roles of these cortical foci in swallowing by comparing brain activation associated with voluntary saliva swallowing and voluntary tongue elevation. … 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 …
