Introduction: Numerical Analysis of Pulse Detonation Combustors

Note: This is just the simulated results done in Ansys fluent 14.0. I may not be able to post a live tutorial for doing this due to some restrictions (research about pulse detonation engines) in some countries. But i would like to share my results with you all since i have done many experimental works in pulsejet engines and many of my subscribers may be eager to know about my future research in pulse combustors. If my video violates any of the rules in instructables moderators can DELETE this instructable. Thank you very much for reading this. 

Edit: Sorry everyone previously i didnt give an clear explanation of my research i would like to present it now. The main reason for doing this simulation is to understand the basic physics and applying it to design a real pulse detonation engine. The simulation is done to see how the engine would work. The detonation combustors are the EXTENSION of pulsejet engine HOW??? because both are hollow in nature, deflagration (or just explosion) in pulsejets but detonation (a violent explosion with high temp and pressure) in detonation combustors. This is just the beginning of my project still i i will be simulating more models over this and will update here.  

Hello everyone, here is an numerical analysis done by me over the pulse detontaion combustors. The analysis is done to have an clear understanding over the physics behind the working of pulse detonation engines. The video contains the working of a single tube combustor with 2inches dia and 1m length. The simulation is done in ansys fluent 14.0. The convergence of the solution is about e-05 i think globally accepted solution is about e-03 so my solution is an converged solution. The results were validated with the NASA CEA (Chemical equilibrium access code) which gives the detonation properties.
The video shows the three conditions they are the initial peak condition Von Neumann spike followed by detonation and finally the rarefaction condition. The results are done for two criteria with con-di nozzle and without nozzle. In case of with nozzle you can see another shockwave travelling backwards which gives an disadvantage for refilling process.

If anyone have further questions about the working of pulse detonation engines please dont hesitate to ask me. Thank you
