Mathematical description of the valveless pulse jet

In summary, the conversation is about understanding the internal workings of a valveless pulse jet and the possibility of finding a book that explains the processes involved in a mathematical manner. The speaker also mentions the various aspects of physics involved in the device and shares a link with some information on the topic. They ask for feedback on their post and wonder if they should post it in a different subforum for mechanical engineering.

Well I want to understand the internal working off the valveless pulse jet, I have red something but everything is qualitative, I would like to ask to you if you know some book describing every process off this kind of engines mathly, including the kadenacy effect.

You have a lot of physics into that device : combustion , sound waves, fluid motion, heat transfer, helmholtz resonance...


Here there is some information, but it doesn't use maths:

I think it's interesting, we can learn a lot from this.




Pd: this is my first post, if you see something wrong or similar, please tell me, thanks.

FAQ: Mathematical description of the valveless pulse jet

What is a valveless pulse jet?

A valveless pulse jet is a type of jet engine that does not have mechanical valves to control the flow of fuel and air. Instead, it relies on the pulsating action of the combustion process to create thrust.

How does a valveless pulse jet work?

A valveless pulse jet works by drawing in air through an intake, mixing it with fuel, and igniting it in a combustion chamber. The resulting explosion creates a high pressure wave that pushes the exhaust gases out the back of the engine, propelling the jet forward.

What are the advantages of a valveless pulse jet?

One advantage of a valveless pulse jet is its simplicity and lack of moving parts, making it easier and cheaper to manufacture and maintain. It also has a high power-to-weight ratio and can operate at high altitudes and speeds.

What are the limitations of a valveless pulse jet?

One limitation of a valveless pulse jet is its low efficiency, as a significant amount of fuel is wasted during the pulsating combustion process. It also produces a loud noise and can be unstable at certain operating conditions.

How is the valveless pulse jet mathematically described?

The mathematical description of a valveless pulse jet involves equations that describe the thermodynamics of the combustion process, as well as the fluid dynamics of the air and exhaust gases through the engine. These equations are used to analyze and optimize the performance of the engine.
