coz area is less thats y pressure is more
How to calculate the ratio of the inlet-to-exit area of the nozzle
My baby brothers baby bottle has a nozzle the size of an elephant!
the simplest engine that is made up of a burning chamber and a nozzle is a rocket.
One disadvantage in the convergent-divergent nozzle as a shock wave can take place in the nozzle A nozzle is a device that converts pressure energy to kinetic energy (increasing fluid velocity on the account of static pressure) For a convergent nozzle there is no disadvantages as it can raise the fluid velocity only for the sonic speed the convergent-divergent type raises the velocity to over than sonic speed making supersonic flow, this could make a shock wave in the nozzle that turns the supersonic flow to subsonic flow
Propulsion by means of uniform cross sectional ducts rather than a varying section (nozzle) is said to be nozzleless propulsion
YES!! propulsion is possible without nozzles contributing in weight reduction and cost reduction. It is only possible when the mass burning rate of fuel/propellant in the duct is increased to that extent to reach the sonic speeds. more likely to be used in missiles and rockets.
To focus the controlled combustion blast of the ignited jet fuel, to achieve propulsion; and also to aim the force to alter trajectory (change direction).
In case of venturi meter, at the diverging section mach number is less than 1. however in diverging section of a nozzle mach number is greater than 1.
Turbojets consist of an air inlet, an air compressor, a combustion chamber, a gas turbine (that drives the air compressor) and a nozzle. The air is compressed into the chamber, heated and expanded by the fuel combustion and then allowed to expand out through the turbine into the nozzle where it is accelerated to high speed to provide propulsion.
The nozzle directs the blast from the burning fuel into a propulsion cone that is the most efficient for the engines output. Without a cone the flow of energy would be unpredictable and would not propel the rocket in the direction desired.
A turbojet consists of an air inlet, an air compressor, a combustion chamber, a gas turbine and a nozzle. Through this constructions, the turbojets provide power to an aircraft when the air is compressed into the chamber, heated and expanded by the fuel combustion and then allowed to expand out through the turbine into the nozzle where it is accelerated to high speed to provide propulsion.
Propulsion
SR nozzle means "Self Reinforced Nozzle".
H. Doyle Thompson has written: 'Hypervelocity scramjet combustor-nozzle, analysis and design' -- subject(s): Airplanes, Jet propulsion 'Laser velocimeter measurements and analysis in turbulent flows with combustion'
Some synonyms for propulsion are drive, energy, momentum, power, speed, or thrust. Propulsion is a noun, there is no antonym except 'no propulsion'.
