@Mammmood - I don’t know much about nuclear reactors. But I do think this has a lot of practical applications. Any technology that requires the rapid injection of a reactant would benefit I think.
I am thinking of automotive applications where you have fuel injection. I am not an expert on cars but I would think that you would want to measure how quickly the fuel enters the chamber to make sure that you are getting just the right amount of fuel.
You would have problems if it the space velocity of the fuel was too more or too less.
