Turbulence issues within tubing (Exair Vortex system)

AI Thread Summary
The discussion focuses on optimizing airflow in a vortex cooling system by analyzing energy losses using the Darcy Friction Factor and Reynolds number. The main concern is finding the right ratio of velocity and diameter to achieve laminar flow, as current calculations suggest that reducing transitions, length, diameter, and velocity could improve performance. There is uncertainty about whether to continue with the current approach or switch to Bernoulli's equation to assess pressure drops. Suggestions include using larger elbows with smooth radii to decrease turbulence and considering air amplifiers as an alternative cooling solution. Overall, the goal is to enhance cooling efficiency while managing airflow dynamics effectively.

Hello,
I used the Darcy Friction Factor from the Moody Diagram along with the Reynolds number to find energy losses inside the cold air tubing of our vortex system. My calculations showed that I should decrease transitions, length, diameter, and velocity. I am mainly concerned with the figuring out an equation to get the right ratio of velocity and diameter so I can get laminar flow. It seems like there is a very short range where I can adjust these two and come out with colder air. I tried writing a DE to figure out how but am struggling with the variables. I am wondering If I should abandon this approach and use Bernoulli's so I can figure out pressure drops at certain parts or if what I am doing is correct. Also is there an easy to decrease turbulence inside an elbow without using guide vanes?
Thanks!

Its a generator that cools air.
 
the air then proceds out and cools CPU's while they are being tested.
 
If you want colder air run your high pressure line right up to your workstation and regulate to your working pressure as close to the work as possible
What do you do with the hot side air?
It is easy to decrease turbulence in an elbow use a bigger elbow with a smooth radius
I personally prefer an air amplifier for cooling it's not as cool as the hot cold vortex but it puts out more air than it uses. The vortex dumps half the air out the back

Thread 'HP Required to move a robot 10meters at 1.5m/sec'

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
