convection & Inverted siphons.............

[fatman57]

I'm currently making something which is convection water cooled.............the problem is i need to make an air trap so the air and water in the system separate.

I have come up with something that looks like an inverted siphon - this is good for water but I am worried about the convection side of things.

My question:
Would the inverted siphon be able to work as well with convection as it would with normal hydraulics?

I've come up with a few models but the whole thing seems rather paradoxical! Even though buoyancy plays a large role in convection currents, i'm thinking in terms of advection it should work even if the inverted siphon may need to run warmer then the rest of the system to match the flow.

Much obliged for any help that anyone can offer.

I am not sure what you have planned, but a siphon will work hydraulically with convection currects.

For example, a frequent problem on hot water supplies is cold water when you turn the tap on. One technique used on residential hot water plumbing systems is to put a loop on the system. You basically set up a convection current so that the water in the loop stays hot at all the times.

thanks!

What i'm building is a loop with a heat source at the bottom. At the top and horizontal is an inverted siphon. I can see that regular hydraulics will work but in terms of buoyancy i am not too sure.

the rising heat will stop at the inverted siphon as it is of greater bouyancy & less dense so less prone to be drawn through the system.

As heat is constantly being added I guess this will make up for it as the buoyancy (expansion) might not be able to keep up with the movement of mass. I'll do some math on it but it is a bottle neck in the system I wanted to gain a greater appreciation of.
