COMPRESSIBLE FLOW THROUGH NOZZLE

When the density of the fluid is function pressure it is called compressible fluid. It is Ma > 0.3.

Stagnation point

It is possessing the fluid flow where velocity is 0.

H/mass(h) = u + PV

For high-speed flows [like jet engines], it is current to combine enthalpy and K.E. into single term called stagnation or total enthalpy.

Advantages and Applications of Convergent-Divergent Type of Nozzles

Convergent-Divergent(C-D) type of nozzles have a lot of application as a propelling nozzle in automobiles and jets. Few examples of the application of convergent-divergent type of nozzles in engineering are:

Steam turbines: In power plants.

Rockets: for providing sufficient thrust to move upwards.

The supersonic gas turbine engine: for the air intake when the air requirement of the engine is high.

C-D nozzles can be seen in water supply pumps or in formula car intake systems or jet engines for providing sufficient thrust to propel at high speeds mostly in supersonic jets.
