Welcome to my UA-cam Channel. I am an Assistant Professor at the University of Ottawa in the Department of Mechanical Engineering. My specialization is in Computational Fluid Dynamics and Supersonic Combustion.
Introduction to Fluid Motion: Pathlines, Streaklines, and Streamlines.
This is a video that introcues basic concepts of fluid motion, using different visualizaton techniques extracted from a CFD simulation of particles flowing around a cylinder.
This video was developed as part of a demonstration for a Fluid Mechanics course that I teach.

FULL LENGTH HD Natural Gas-Powered Rotating Detonation Engine (RDE) Simulation (HD with music)
Переглядів 3,4 тис.4 роки тому
#detonations #cfd #computationalfluiddynamics #engineering #aerospaceengineering #combustion This is an *updated* video of a toy-model RDE simulation. This is a 2D Euler simulation of a self-similar unwrapped RDE geometry. For simplicity, we have assumed calorically perfect gas with one-step combustion chemistry, using model parameters that correspond to premixed methane-oxygen (CH4 2O2). The v...

Pulse compression detonation system simulation
Переглядів 4794 роки тому
This is a large scale 2D simulation of a single pulse from a pulse compression detonation system, modelled using the CLEM-LES. What is shown is the temperature field. This work is featured in: Maxwell, B., Korytchenko, K., and Shypul, O. Numerical simulations of compression and detonation strokes in a pulse compression detonation system. In Ivanov, V., Pavlenko, I., Liaposhchenko, O., Machado, ...

This is a preliminary simulation of a natural gas powered rotating detonation engine. The simulation is 2D Euler with one-step chemistry.
Beautiful flow demonstration..Nice to hear, What's the name of the music?
great explanation. tnx
Thank you so much for the video!! I'm in my introductory fluid mechanics course and I was so confused as to how these three were different, but once I could see the unsteady state example that was way too hard for me to picture without a rendering, it totally clicked, again, thank you so much! <3
this is very cool, thank you
I need to learn to do this
Hi sir, how does streamline change direction over time?
Yes! As long as the vector field change for any reason!
I'm in hurry to learn the way to define such a simulation... Can you please share step by step of simulation... I want to simulate the leakage of hydrogen pipe to air surounded it in 3D model
Hi, the details of the simulation was published here: doi.org/10.1016/j.ijhydene.2018.03.197 The code is of course not a packaged CFD code, but rather an in house solver. Happy to answer any questions: brian.maxwell@case.edu
At what rpm would the shock wave travel around the combustion chamber?
Hello! Could you share the tutorial of this video which I want to learn so much? Thank you very much!
A jet engine with 11 rotating detonation combustors that are injected with detonation waves by a coupled and geared radial engine ...The radial engine is essentially a pulse compression detonation system that injects detonation waves into the rotating detonation combustors. The radial engine is clutched. In other words i am trying to fit the pulse compression detonation system into a jet engine in order to produce canular combustors that are themselves rotating detonation combustors. Is this possible?

which software are using for simulation?
Hi Manish, we have our own in-house research codes that we've been using. You can check out our publications: scholar.google.ca/citations?user=Vwn4r5gAAAAJ&hl=en
