I'm still trying to figure out how the original object produces thrust, I'm assuming it's not the same way as a rocket engine which expels mass at speed outwards, but by fluid (air) producing pressure against the surface ?
Picture the following model, and by having pressurized air come out of...
Sounds like I will need to either perform some calculations, or simply make different models that have different shapes but are all straight and see if I can get a better output out of a particular one ...
So I think what you're implying is the force difference between the straight and bent funnels would mostly be related to length of the funnels (the in and out diameters are the same),- I'm still not sure why the bent funnel seems to be creating more force ...
The fact that the straight output would be more efficient thus creating more force.
But maybe I'm thinking about this wrong :)
I was looking at this from the point of view that the ejected mass creates the force ...
I am pretty sure it's not in the way, as the sensor basically touches the object, so there's virtually no movement required,- except just enough to read the force.
My pressure tank only sustains 100 PSI for a short time, so I'm essentially reading that burst force,
but I as well thought that...
Yes, it looks similar to this, with the sensor (cyan), rails (blue) that allow the object to move up/down on the axis (red) and create force in the direction of the red arrow ...
What's interesting was that when the bent pipe wasn't getting bigger towards the exit (like a funnel),
but instead was the same diameter throughout the force was actually smaller than the straight out exit.
Maybe there was air turbulence and not as much fluid was changing direction ...
The...
Hello,
I am doing some quick experiments testing how pressurized air behaves when being ejected from a straight vs. curved object,
and I am wondering if this is the expected behavior and a possibly quick explanation of why this would be behaving this way...
I am using the model below and...
I'm not sure the software can simulate this properly, after all the only interaction this simulation shows
is how the 2 masses interact with each other when they're either sent directly out (by 1st making contact
with each other - left side) or out on a curved path (right side).
I believe it would be no different, I think even a simulation using fluids would show the results.
Is there a good fluid simulating software available that could be used ...
Yes I realize that of course, but since a rocket can be very roughly simulated by throwing payload off that has a certain mass and velocity to create thrust, I figured we could now see what happens when the payload is thrown at 90 degree on a curved track, versus in the opposite direction of the...
I don't know of any programs that would allow such simulation, at least nothing open source or free.
I was just trying to approximate Newton's 3rd law by using mass/velocity of ejected material,
as I don't see how a curved designed would be in any way more efficient, as was already mentioned.
It's an old program I have called Interactive Physics, and I was using a mass of 19 kg for the U-shape, and for the "fuel" there's a mass of 0.5 kg for each of the balls, and they are traveling at 10 m/s. On the left side they are traveling downward, and the right hand side of the simulation...
Thank you all for the comments and suggestions!
First of all I was thinking that by testing this with CO2 with air around it wouldn't simulate a rocket properly because quite a bit of force would be generated by CO2 pushing against the air, forming a sort of pressure bubble, but considering the...
