Given that the equations involve continuous functions of some bulk properties of a fluid, while the fluid itself is made up of discrete particles, is there anything fundamentally or metaphysically problematical if these blow-ups are unavoidable? Or is it about finding practical ways to avoid them when modeling real-world scenarios?
- lgeorget 7y agoI guess that it's just that it would be super convenient if the equation that work for a fluid would work for any part of the fluid, however small it is.
- steve76 7y agoI don't think the fluid is made up of discrete particles as far as pressure goes. The discrete particles are covalent bonded. If they blew up, I think you could put an elbow on a copper pipe, rotate it just the right way with fluid flowing through it and get a voltage. Instead you get cross flow and cavitation. Perhaps it does happen, and it can't be detected due to matter waves or not being able to accurately trace the path of "something thermal".
