Fluid and Gas Flow Analysis and Simulation

[Anonymous]

Why I think we could use this: Adding this feature to fusion would make it so much more powerful. Any sort of ballistic or aerodynamic project would be vastly improved. Designing rockets and engines could be more accurate and let our community get into a whole new level of complexity and quality of design.

What it would need to include: Allowing us to input mechanical properties of the materials we want to work with would be absolutely essential to getting real results. tensile, shear, thermal modulus, etc. would let us see actual pressure and pressure relative to our material capabilities.

Allowing us to use faces and create origins of force and rate of acceleration of said force would also be crucial.

We could use this for hundreds of projects across dozens of industries.

sir,

Is it possible do flow analysis of following criteria

• I want to do analysis on nozzle design and want to know about the flowing particles through nozzle.
• how to calculate velocity of particles while travelling through the nozzle.

Yes indeed! Fluid and gas analysis will help you accomplish this in a way. It will show you the pressure differential going through the nozzle so you can see your areas of high and low pressure and partially visualize the test "particles". the nice part of this is that you can get an idea of how your geometry changes affect areas of high and low pressure and what kind of turbulence is being generated. The only thing I'm not sure that it can appropriately address is changes in viscosity due to pressure. For your purposes you might have to adjust particle density and energy for the simulation and run multiple to check how your nozzle reacts to starting, holding, and dropping pressures. hope this helps. velocity calculation can be accomplished by understanding ratio of compression of the sim. In your case research the math behind the Venturi effect to get an idea of how to interpret the data you're seeing and stack it against your material specs and whatnot to make sure you're within the zone you want for your operational lifespan. Hope this helps!
