Thanks, I will browse through those and hopefully find a small sized one.

Hello, would someone know where could one purchase a radial inflow microturbine of diameter 1 - 2 cm All I need is a contact web address or similar of the manufacturer or seller. Many thanks

Hi racookpe1978, Power: in the order of hundreds of watts, up to a kilowatt. At Inlet: room temperature + up to 100K; pressure of 2-5atm gauge; subsonic nozzle injection. Tip speed of the rotor is subsonic, but should be capable of reaching about 300-330 m/s (50,000 rpm at 12cm diameter). Rig...

Hello All, where could one purchase a radial inflow turbine wheel and its manifold/nozzle assembly? I looked on the net but all I could find is this link. Would someone know what is the cost of such assembly for a turbine wheel with radius of 6cm (cold flow, about room temperature gas)? We...

Hello, I am trying to estimate the mass flux (m dot) of air (ideal gas, compressible flow) through adiabatic pipe. Can this be done without involving the velocity or Mach number? Forgive my ignorance... I can get the following: inlet pressure, inlet density, pipe cross-sectional area, pipe...

I would like to thank to all who have contributed to this thread.

macmet, I certainly agree with you. My question is general... I only need to know some real-life exit conditions, so as to get a feel what is out there. Also, would like to learn about how kinetic energy is extracted from the gas just before turbine exit, because it is not straightforward, as I...

Would someone else care to venture an opinion? What is, as a matter of principle, the method of slowing down the gas at turbine exit, so that its kinetic energy is fully extracted and converted to shaft-work. While such energy extraction makes perfect engineering sense, one can wonder how it is...

If I can have the exit diameter and the RPM, I can assume the gas leaves with the blade tip velocity = omega x R. This way, one can have an estimate of the kinetic energy of the gas. Knowing the pressure at outlet gives info about the potential energy of the gas. Then one needs the flux to...

Hello, would someone be able to provide real-life example(s) of the outlet conditions for any turbine? Such as gas velocity, mass flux, pressure... I am trying to get a feel for the available energy at a turbine's exhaust. Many thanks

I am hoping the volume of the tank is listed on the nameplate as well...

Thank you, Frank1344; yes the vessel is in Ontario [smile] The volume of the vessel is of a particular interest... But unsure if it is listed in one of the numbers in the nameplate

Hello, Would you be able to interpret the nameplate info on this vessel? We are using an older (1960s) pressure vessel, the nameplate reads CRN. 4800.5. N.S.P. 3442. TS.55000. W.P.236.TEMP.354. SH.4375.HDS.387. UW.12.C.31.10.62. H.W.C. This is what we know: CRN is Canadian Registration...

Once ready, the assembly will be run in a CFD solver and its imperfections (like the crack above) have no bearing on the main phenomenon we are simulating. But they do mess up the mesh, which I need to run the solver. Thanks to rfus for suggesting the loft between the 2 mismatched faces. I will...

Wow, thank you for the so many replies. I'd like to post the assembly and am sure people will resolve the problem I have. The thing of it is - the designs do not belong to me only and I have to keep them confidential (sorry, I know this is no fun). Anyways, this work is a part of a...
