Taylor couette
WebTaylor-Couette flow is the flow of a viscous fluid sheared in the gap between two rotating coaxial cylinders. Sometimes called the “hydrogen atom of hydrodynamics,” Taylor … WebThis hypothesis motivates a separate study dedicated to this important aspect of the Taylor-Couette system at wide gap (large clearance) that is currently underway. In addition, this study can be extended to an investigation into the effects of a non-zero axial flow rate and of a radial shaft load on the flow, towards building a higher fidelity model of a bearing …
