Hello,
Are there any means to compute properties of produced fluids (assumed water-cut, API gravity, black oil model) for a range of pressures and temperatures? I need to use the viscosity, density and sp. heat values for a CFD simulation.
Please view the uploaded PDF file. Will this arrangement work as a 2-axis gimbal? If yes, is there a software to perform kinematic (rigid-body) simulation of this arrangement? Can Unigraphics NX 6.0 do a motion simulation for this?
I often need to size piping/tubing to allow highest flow-rate for heat transfer purposes, and I am not very familiar with Piping or Pipelines-related industry standards.
So, I have to turn to web-based sources for information. Many of the supplier websites recommend the use of the "pipe/flow...
My co-worker is simulating a ring-shaped geometry for me. The ring has a number of holes along the circumference such that a sectored 3D model can be used. The attached screenshots show the geometry as modeled in UniGraphics NX 6.0.
The whole ring.
Cutting planes used for obtaining sectored...
The results of sectional-3D FEA on a Thrust Runner show that the Runner "bows" under the thrust load. The axial displacement of the periphery of the Runner is ~60 µm. The thickness of fluid-film between the Thrust Runner and Tilting Pads is estimated to be ~10 µm.
Radial interference of 5...
The results of FEA on a Thrust Runner show that the Runner "bows" under the thrust load. Radial interference of 5 mils/inch diameter is modeled between the Shaft and the Runner. The applied loads are: (i) Interference, (ii) Centrifugal, and (iii) Axial Thrust.
The axial displacement of the...
Howdy folks,
I need to perform the structural design of Thrust Collar and Shaft Sleeve for (hydrodynamic) tilting-pad Thrust and Journal Bearings, respectively. Can someone point me to guidelines / best practices to be followed for the mechanical design of these elements? To be specific, I...
Can anyone advise on the susceptibility of flexible graphite (trade names "Grafoil", "Papyex" etc.) to explosive decompression (ED) or rapid gas decompression (RGD) in a multi-phase hydrocarbon production environment?
The application I am considering does not involve sealing with flexible...
Most of the engineers on here probably know that ceramics are being widely used in both sliding (or hydrodynamic) as well as rolling element bearings. However, Silicon Nitride ceramics seem to find more favor among rolling element bearings whereas Silicon Carbide is used mostly among sliding...

A fluid bearing supplier wants us to specify impact loads in terms of g-forces. Does anyone have any idea on how to convert expected impact loads into g-forces?
I come from a mechanical engineering background and don't know anyone to ask this question.
Please point me to industry codes, books and/or guidelines relating to best practises involved in performing structural/mechanical design with *unreinforced* concrete.
I am looking for some guidance on designing pressure vessels with brittle materials.
Ideally, I would prefer to get info on ceramics. I do realize, however, that is probably not going to be very straight forward. Alternatively, I can possibly use principles involved in pressure vessel design...
Can anyone point me to an industry standard or test specification or even a guideline on how to define a qualification and/or performance test regimen for a set of tilting-pad (thrust and axial) bearings?
I need a generate a document that details or at least outlines such a test protocol.
I need some help in selecting a heat transfer fluid for an in-house test facility. The facility will involve a insulated heating tank which would heat up the fluid and maintain a steady buffer for the pump to circulate from. The fluid is pumped into a cooling chamber where it exchanges heat with...
