exhaust
rocket engine seems to be of this type. as the air-fuel mixture is burned and flame is made to propogate through nozzle to provide thrust
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.
Air intake and exhaust. Air comes into the intake located at the front of the aircraft and exits at the rear of the aircraft. This is such a load of crap! A jet pipe is located at the back of an engine, just after the exhaust! It is connected with a gas tight sealing ring and just before the propelling nozzle. And pipes the exhaust gasses out of the fuselage/Wing... A/C engineer.
The engine sucks air in at the front with a fan. A compressor raises the pressure of the air. The blades compress the air. The compressed air is sprayed with fuel and a spark lights the mixture. The burning gases expand and blast out through the nozzle at the back of the engine. As the jets of gas shoot backward, the engine and the aircraft are thrust forward.
An air horn is simply a canister of compressed air, which at the press of a button realeses some of the air into a nozzle. When air passes through the nozzle, a sound is emitted. (like a trumpet)

Depends. It could be considered forced convection if the object is also air. It is called jet propulsion when the blast of air comes out of a jet engine, and moves an aircraft.
the air which comes from atmosphere is called as fresh air,the air which comes from room again to cool called as return air and the air which is out from fcu ,ahu ,etc., is known as cool air.
Convergent nozzle indicates nozzles will converge with an end closing together at the end divergent nozzles increase size at the end. If air flows in this direction: ---> Convergent nozzle > Divergent nozzle <
Air nozzle velocity can be calculated using the formula v = sqrt((2 * P) / ρ), where v is the velocity in meters per second, P is the pressure in pascals, and ρ is the air density in kilograms per cubic meter. Simply input the values of pressure and air density into the formula to determine the air nozzle velocity.
Air comes in a engine that ignites the kerosene which then makes trust.
To understand why air rushes into a vacuum cleaner nozzle we need to trace air flow in the machine. Let's do that. The motor in a vacuum cleaner spins a fan, and the fan moves air. The air intake for the fan is connected to ducting that is routed to the nozzle. As the fan forces air out in its exhaust stream, it creates low pressure on the suction side of the fan. This low pressure (a partial vacuum) is felt along the air path to the nozzle. At the nozzle, outside air pressure forces air into the ducting where air pressure is lower. The moving air has picked up debris and carries it along. That debris ends up in a bag or filtered dirt canister or someplace else where it can accumulate and be collected for disposal. This applies to machines that have bags or filters to get the debris out of the air stream before it goes through the motor to keep it cool. Some machines isolate the motor from the air stream created by the fan, and the motor is cooled by another fan. These "direct" vacuums operate in a way that sees the air stream and the debris pass through the fan and be driven into a bag. The operation of the fan has created a low pressure area along the ducting between it (the fan) and the nozzle. Outside air pressure, being greater than the low pressure created by the fan and ducted to the nozzle, forces air into the nozzle.
