nice to see some post in this group i remember seeing a mention about such a pump being used to ventilate a mine on a very very large scale .. using a pulser...
... Your are refering to something like the Ragged Chutes Hydraulic Air Compressor on the Montreal River in Canada. It is described in some detail at: ...
... It is a design project, not a working machine. Do you doubt it would work given a larger deltaT? (just curious about where your objections lie). ... This...
Just wondering if you have factored in energy losses in the tromp and bubble pump due to turbelence? And the different densitys of the hot and cold water and...
Mainly I was trying to figure out ahead of time if it would be worth building one and seeing if it works. Turbulent flow needs to be avoided by using large...
This is just an overview. And it is also perhaps part of the reason scientists dont seem interested in researching the pump. The physics is incredibly...
Hi, stan, What would I live on in the 7 or so years it would take to do the phd and the research? And, who would provide the money to do the research? I think...
I put 2 explainatory videos on utube They are at http://www.youtube.com/watch?v=QOn7Zu3CCxo and at http://www.youtube.com/watch?v=0topdMcpNMk The first one...

I don't remember if I contacted the university of lanchashire or not in my sending out of info about the pump over the years. But anyway, they are researching...
http://www.youtube.com/deawhite My Bad brother let the poor little girl get soaked! Anyway, he took the video with his digital camera, a couple of days ago. I...
Hi, I went ahead and set up an album in the photo section for the first step in sharing my pulser pump model experiments. I do not know the correct protocol...
I posted a few pictures of the model pump in my album just now. This pump is simple and easy to make. I used leftover materials from other projects. This is...
I do not think you can post video to the group. You may upload video to youtube or another popular open video service and post a link to the video. youtube...
Put them on youtube and then link to them From: pulserpump@yahoogroups.com [mailto:pulserpump@yahoogroups.com] On Behalf Of color131709 Sent: Tuesday, January...
The link below led me to look up "slug flow" where I found a number of things including this page: http://www.pe.utexas.edu/2phaseweb/flowtwo.html -Timothy...
http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1678-58782007000300011&lng=pt&nrm=iso&tlng=pt is the link. It has some nice pics of different flow...
It seems there is actually quite a bit of relevant research and info out there; it's just that they use different, more complex terminology. I had a simple...
I have asked for "peer review" (which basically means someone else confirming that the pulser pump works) for years. Matt in Cornwall obliged a few months ago....
This is really neat! I want to see if I can use this in an aquaponics system to get the water from my sump back up to my fish. I am only starting to build. The...
Much like how a coil pump works. Also called a spiral pump. Is a neat concept. It works perfectly in a river as a wheel... just coil the piping bigger and...
Can water be recycled in a closed system? Say from sump.... down 1st pipe into Pulser pump chamber..... up 2nd air and water mix to a high top tank using coils...
I did try something like steps over the years. The problem is the steps cause pressure drop. I found the best way seems to be either straight up or at a...
As long as you get the compressed air from the stream, you can do this. So you need a "tromp" in the stream and it provides the compressed air to work the...
No; water can not be effectively recycled in a closed system of this type. This principle requires quite a bit more moving water than is pumped. (It's a...
Thanks Timothy. Much like a ram pump then.... the waste. I started realising that. Needs a river or stream. My river is too fast and too deep. Can't build a...
S. Holloway made a model pulser pump in January that pumped to nearly 22 ft high. It is in the photo's section. Mat in Cornwall also made a model. He put a...
