In this article, we are providing you with the Compressible flow study notes for GATE, BARC other Mechanical exams. It is an important part of Thermodynamics & its Applications Subject that has a good weightage of the questions to be asked in various mechanical engineering exams.

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.
