Turbulence issues within tubing (Exair Vortex system)

Click For Summary

Discussion Overview

The discussion revolves around the challenges of managing turbulence within the tubing of an Exair Vortex system, particularly in relation to achieving laminar flow and optimizing cooling efficiency. Participants explore theoretical and practical approaches to reduce energy losses and turbulence in the system.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant used the Darcy Friction Factor and Reynolds number to calculate energy losses and is seeking an equation to optimize the ratio of velocity and diameter for laminar flow.
  • The same participant is considering whether to switch from their current approach to using Bernoulli's equation to analyze pressure drops.
  • Another participant suggests using a larger elbow with a smooth radius to decrease turbulence in the tubing.
  • There is a suggestion to run the high-pressure line closer to the workstation to improve cooling efficiency.
  • One participant expresses a preference for air amplifiers over vortex systems, citing higher air output efficiency despite lower cooling effectiveness.

Areas of Agreement / Disagreement

Participants present multiple competing views on the best methods to reduce turbulence and improve cooling efficiency, with no consensus reached on a single approach or solution.

Contextual Notes

Some assumptions regarding the definitions of laminar flow and turbulence management techniques are not explicitly stated, and the discussion does not resolve the mathematical complexities involved in the proposed approaches.

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
