How to model a Shell Bearing in MATLAB Simscape for Oil Flow Analysis.

I am building a 1D model of an IC engine’s oil-flow circuit to understand the flow distribution through the nozzles used to represent the physical system. The 1D model is being developed from the engine’s 3D design.

Now I need to model a shell bearings (semi circular in shape), one will have fluid flowing out of grooves and circumferencial clearances, along with a shaft (cylinder rod, diametrical to the semi-circular shell bearing) and the other will have only circumferencial clearance to let the fluid out.

I have used Pipe(TL) for mapping the path of oil flow but I am not getting an acceptable value from the Shell Bearing's flow analysis.

Is it possible for you to include a diagram to help the community better understand what you are trying to model?

I would imagine the "circumferencial clearances" (CC) is much smaller than the circumference (C) and length (L) of flow path. In such settings, you can set the hydraulic diameter of the pipe to be CC, the area to be CC*C and the length as L. That will give you approximately the same surface area and hopefully reasonable pressure drop.

this will be a better representation of how I want the oil to pass. The Front Main Oil-hole is the point from where Oil enters the shell bearing. In my case the oil thengoes out from the center or another oil hole and then flows to the other components, but that is the one where the fluid flows out of grooves and circumferencial clearances. The one I am asking dosent have any outlets, only microns of clearance along the circumference to eject the fluid out of the bearing.

I hope that this description and the link helps. I am not allowed to share the actual design or the picture of it according to the privacy rules of my organization
