Question

Numerical investigation on effect of divergent angle in convergent-divergent rocket engine nozzle

Answer 1

In rocket, a nozzle is used to control mass flow rate, velocity distribution and pressure of the exhaust gas that emerges out from the combustion chamber. The nozzle is used to alchemize the chemical and thermal energy generated in the combustion chamber into thrust. The nozzle metamorphoses the high pressure, high temperature, low velocity gas in the combustion chamber into high velocity, low pressure and temperature. The design of nozzle is an important aspect for achieving the maximum Mach number and minimum.

The different divergent angles used for analysis are 9°, 12°, 15° and 18°.
