Vortex air entraiment
    #379678 - 08/27/01 12:11 AM (22 years, 7 months ago)

Alright I'm going to add to the ideas spawned from Mcmans hydro pod design. I've been kicking this idea around for about 2 weeks now. I want to try and design a system of air entraiment, in a circular terrarium (such as a modified bucket or drum), that uses a means of mixing air similar to that of a "Whirl Wind" vacuum cleaner. I want to try and get the air in the bottom to begin spiraling then be moved gradually up the chamber and out an air vent. But I'm gettin hung up on how to get the vortex of air formed. Any ideas/suggestions would be greatly appreciated.

Your dilemma is solved by the shape of the container itself! If the air source is directed so that it is aimed more 'ALONG' the circular wall of the container than at (perpendicular to it) it... it will travel 'around' and circle back. To achieve an upward spiral, just aim along the curved side and slightly upward.
Two issues that occur to me are 1) the source of the air will have to be relatively strong if you wish the 'current' you are creating to spiral all the way to the top of bucket. 2) Items placed in the container (perlite, trays, etc...) will obstruct and influence the travel path of the air current. I'm thinking that if you take the single air pump hose thats going into the bucket and use a splitter (bifurcate the line) to create two air output ends... then you could have one at the bottom of the bucket (aimed along/upward the curve) and the second air output end about midway up the bucket (aimed along/upward). This might allow the second air output end to augment and maintain the circular air flow all the way to the top of the bucket. Question where are you placing the exhaust valve?

I'm gonna try and use a filtered cage blower in line with a cool mist humidifier, so there will be no perlite to worry about. The exhaust valve will be placed near the top of the container. Exactly where and at what angle will have to be worked out with the direction of the air flow.

Consider a 'scoop' style outlet to collect/capture and vent the vortex current. Much the same as an air scoop functions on the hood of a car.

That is a very popular(well to knife makes) forge design...the propane inlet is not angled though, its just made next to the wall of the pipe so that the pipe is a ramp for the heated air.the forge is a sideways pipe though.Dont have any idea to help you just wanted to let you know that you may get somewhere reseaching gas forge design....good luck
