AI Thread Summary
The discussion explores the feasibility of using sprayable materials to create a supportive skeleton within a 3D labyrinthine structure, likened to a hollow tree with branches. The concept involves inserting a tube into the trunk and filling the structure with a spray that forms solid lines of material to prevent collapse. Suggestions include using expanding polyfoam, commonly used for insulation, or a stronger polycarbonate mix that expands similarly. The need for clarification on the specific requirements of the material application is acknowledged. Overall, the conversation focuses on potential materials that could achieve the desired structural support.

hello!

is there a material that will be sprayed through a tube inside a 3D labyrinthine structure and it will create a skeleton inside that labyrinthe?

thanks!

I very much doubt it, but can you clarify your requirements a bit?
 
yes, imagine a structure like a tree with branches
now imagine the branches to be hollow
then, insert a tube into tree's trunk and fill the whole structure with a spray

now, that spray should create inside that structure a skeleton that support the hollow branches to collapse

the skeleton can be formed by solid lines of material that will run in parallel with the walls of the hollow structure, or the solid lines can be vertical to the hollow structure's walls
 
Okay, then. That's still a little vague, but I think that I have the gist of it. Would expanding polyfoam, as is used for insulation, serve your needs? I think that there is also a polycarbonate mix that expands similarly but is far stronger.
 
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
