(Appendix-B of Anderson’s textbook) • Next, we find the sonic reference area behind the shock using the area-Mach relation. i.e., 2018-04-06 · If no heat is added, and there are no pressure losses in the nozzle, the total pressure and temperature are also constant. By substituting the sonic conditions into the mass flow equation in the box, and doing some algebra, we can relate the Mach number M at any location in the nozzle to the ratio between the area A at that location and the area of the throat A* . The de Laval nozzle is an example among propelling nozzles, that are widely studied devices that turn a fluid (gas) turbine into a jet engine. A de Laval nozzle is constituted by an hourglass-shaped tube, strained in the middle, utilized to accelerate a hot pressurised gas to a high supersonic speed into the thrust direction.

Among many applications of the de Laval nozzle are rocket propulsion and supersonic jet engines. The de Laval nozzle transformed a subsonic ow through a pipe into a supersonic ow by varying the cross-section of that pipe. Ignoring the transverse components of the ow, the derivation for this process arises as follows.
