Why the combustion chamber made of material that can withstand a high temperature?
The combustion chamber needs to withstand high temperatures generated during fuel combustion to prevent deformation or failure. Using materials like ceramics, superalloys, or refractory metals ensures the chamber can endure intense heat without melting or compromising structural integrity. This is crucial for efficient and safe operation of combustion engines and systems.
Which element is used in rocket fuel?
Liquid oxygen is commonly used as an oxidizer in rocket fuel because it can react with a fuel source to produce combustion. Another common element used in rocket fuel is hydrogen, which serves as a fuel source due to its high energy content and efficiency in combustion reactions.
What is the combustion chamber size of a Chevy 350 stock head?
The combustion chamber size of a Chevy 350 stock head typically ranges from 64cc to 76cc, depending on the specific cylinder head casting.
What engine is an example of an internal combustion engine?
The four-stroke engine used in automobiles is an example of an internal combustion engine.
What is it called when combustion occur in a rocket's engine and releases heat and pressure making a larger pressure gradient inside the rocket than outside which causes the gaseous products?
This process is called thrust generation. The combustion of propellant in the rocket engine produces high-pressure gases that are expelled through a nozzle, creating a thrust force in the opposite direction as a reaction. This thrust force propels the rocket forward in accordance with Newton's third law of motion.
What is the reason for having a combustion chamber on a rocket?
A combustion chamber is where combustion occurs in a controlled fashion. Because the basic idea of a rocket is burning fuels and directing them in the opposite direction to that of travel, a controlled burning - as happens in the combustion chamber - is exactly what a rocket needs to work.
What happens when gas molecules hit inside of the rocket's combustion chamber?
The rocket pushes back on the gas.
What happens when gas molecules hit the inside of a rocket's combustion chamber?
The rocket pushes back on the gas.
Where do the rocket exerts force in pressure?
Rockets exert force at the upper part of the combustion chamber. This pushes the rocket forward.
Is rocket engines are internal combustion engines?
YES the oxidizer and propelant are mixed into a chamber the ignited.
How does a rocket?
The critical part of a liquid-fueld rocket that provides it with its ability to "fly" is the combustion chamber, sometimes, but not always, including a shaped nozzle, positioned at the rear (bottom) end of the vehicle. The combustion chamber is open at one end. In its simplest form the chamber is bowl-shaped (a half-sphere) with its open end pointing down, away from the vehicle. The Saturn V, used for the Apollo missions, used this kind of combustion chamber. Combustible liquids are pumped into the chamber. This may consist of a single, essentially self-igniting, liquid, or it may consist of two or more liquids which, when combined, can be made to combust. The Saturvn V used kerosene (the fuel) and liquid oxygen (the oxidizer). When the engine is "lit" so that the fuel is burning (more like "exploding") inside the combustion chamber it creates tremendous pressures inside the chamber. Some of that pressure is against the upper, inside portion of the combustion chamber, and it is that pressure (force) against the upper inner surface of chamber that propells the rocket. Since the chamber is open at one end the forces in that direction cause the combustion exhaust gases to exit the chamber. This causes an "exhaust plume" out of the back of the rocket engine. Some have described this as being a situation where the exhaust plume "pushes" the rocket, or that it is the exhaust plume that causes the rocket to move, or that the rocket "rides on top of a trail of fire". But that is not the case and is not a correct way of describing what happens. The exhaust plume does NOT move the rocket. The exhaust plume does NOT cause the rocket to move. Rather, the combustion pressures inside the combustion chamber causes both the rocket motion AND the exhaust motion. Some have also noted that, since Sir Isaac newton's Third Law Of Motion states that " For every action, there is an equal and opposite reaction ", it is therefore the rapidly exiting gases from the rear of the rocket that cause the rocket to move forward. Again, this is not a correct description of the situation. Yes, the Third Law of Motion applies to the rocket. Yes, there is both a forward motion of the rocket and a backward motion of the exhaust gases. But it is not correct to say that the one (exhaust gasses) CAUSES the other (the rocket motion). Yes, there is a mathematical, physical relationship between the motion of the exhaust and the motion of the rocket (taking in to account their respective masses), and given a measurement of one you can calculate the other (e.g. knowing the velocity and mass of the exhaust gasses and the mass of the rocket you can calculate the velocity of the rocket). But it is NOT valid to say that the rocket motion is CAUSED BY the exhaust gas' motion. The correct view on this is that both the motion of the exaust gas and the motion of the rocket are caused by the combustion pressure inside the combustion chamber.

If the name Rocket Lorena stove derives from the operation principle of this stove how is it that the operation of the stove compares to that of a rocket?
The Rocket Lorena stove derives its name from the addition of elements of the Rocket Stove into the Lorena Stove. Lorena is from a combination of the Spanish words for 'clay' and 'sand', which are mixed to make the mortar used in its construction. I am guessing here that the Rocket Stove may have gotten its name from its use of an L-shaped combustion chamber called the "rocket elbow," which rockets the combustion upwards. It thereby allows full combustion of the fuel at the front of the stove while localizing the burn to just the ends of the sticks inside the combustion chamber, which is at the crook of the elbow, thereby conserving wood. The Rocket Lorena has added this "rocket-elbow" combustion chamber to the Lorena stove. It has also added better insulation materials, such as pumice, clay-sawdust or clay-husk mortar, or whatever else is locally available, around the firebox and the rest of the heat passageway. Additional thought: Regarding why the Rocket Stove is called a rocket, it might also be because the rocket stove looks somewhat like a rocket. Or else because the stove's combustion chamber bears some analogy with the combustion chamber found in liquid-fueled rockets. Though the Wikipedia listing for rocket stove does not answer this mystery, it does give links to sources that may be able to do so, such as the Aprovecho Research Center. Apparently, the 'rocket' half of the name of this energy efficient stove is derived also from the swooshing sound the stove makes as the heat trys to escape from the top of stove.
How do rockerts work?
At the center of every rocket is a device called the combustion chamber. Here rocket fuel is mixed and ignited into a controlled explosion. The explosion produces a pressure on the walls of the chamber. There is only one (external) opening to the chamber which opens to the rear of the rocket. Through this opening the exploded products escape, because of this there is no force exerted by the wall of the chamber against the explosion. This means that there is an unopposed force on the opposite end of the chamber - the force that moves the rocket 'forwards'.
Where are hot gases with a lot of pressure on a rocket held?
They are generated in the combustion chamber. Then they exit the rocket through the nozzle. The gas is never actually "held" in the sense of a storage tank.
How does the liquid fuel rocket work?
by burning liquid fuel with a liquid oxidizer in a combustion chamber connected to the exhaust nozzle. this generates thrust.
Where does a rocket keep oxygen to burn?
Only liquid fuelled rockets (and then only some) rely on oxygen as the oxidizer. It is carried in liquid form in a tank (or tanks). It is them pumped and mixed with the fuel in the combustion chamber where the combustion reaction takes place. The combusion products then exit the rocket nozzle. In solid fuel rockets, the oxidizer (whatever that may be) is usually mixed with the fuel.
