i had a nice person make my new addition.

i had been using a large tube for dewatering as some had seen in the venturi drying videos.

well as the width was limiting my choice of uri or diffusers i decided to go for a cone bottomed 205.

now, i had also seen one of these...

so, 10 mins after looking at that page, i was presented with this.

im well chuffed as all the pipework, and taps were supplied too.

i will upload some pics of the welds and the nozzle in action tomorrow.

well chuffed i am.

Excellent work there, really nice fan.

Can you estimate how thick the oil sheet is in the center? I don't think he edges would be the same.

GedsJeep · « **Reply #7 on:** May 03, 2015, 10:44:16 PM »

i did notice that the edges had a band along them, but i was more preoccupied with dangling a 500 quid phone in there......

it was way less than a millimeter and even thinner when hot.

it needs tweaking as there is a strange effect.

when you put your face level with it and open the valve, there is a marked increase in air flowing with it.

the oil then "bends" upwards slightly and goes everywhere.

its as though the oil is creating its own "lift" due to the shape of the section. "think wing"

i will have my mits on a few more of these at different angles by wednesday, and will post vids accordingly.

that must be the air pressure travelling round the inside the drum (from the jet speed) both sides giving it lift at the end where it must be quite a fine spray pattern. sort of a vortex or cyclone???

one thing I did on my build was made the cone bottom outlet high enough off the floor to get a 20 ltr cubie under to drop glyc, but in doing this height becomes an issue (specially in a shed - lower roof)

GedsJeep · « **Reply #9 on:** May 04, 2015, 12:23:20 AM »

yeah, my shed is only 6` tall, luckily im short.

simons brief was to allow a washing up bowl underneath, but keep it short so i can see in the top.

im going to try some 100 deg c oil, a steeper angle and an extension on the downpipe when the updated bits arrive on wednesday.

im only going to be doing 150L runs, so i have plenty of space to play with.

utah are selling them at 50 dollars. i think simon could offer them a bit cheaper.

Really

I need one of them nozzles for drying bio.

Looks great

GedsJeep · « **Reply #13 on:** May 05, 2015, 05:58:11 PM »

give us a few days to try different angles and perfect them.

i`ll ask simon to quote a price mate.

simonallen · « **Reply #14 on:** May 05, 2015, 08:10:29 PM »

well,
once we have the spray pattern how we want it I would be able to sell these for around £20 each, and could supply them as blanks for you to experiment with spray patterns yourself. But please dont see this as a business thing, It's a hobby. The £20 would cover the cost of the materials and the time on the lathe. Would also need to know how people mount things, Ged's pipework was originally 22mm copper pipe fittings which would need a compression joint but the setup I have sent him is all 1/2" bsp air pipe as that's what I have setup for. Either fitting would be fine but I would need to know what people need when they order.

I've sent another nozzle to Ged today, so am awaiting his report on it. Bear in mind, this is just me playing with angles, by no means are my fluid mechanics as good as my land rover mechanics
