Flow through an annulus transport phenomena
WebOct 21, 2011 · Taylor-Couette flow is the name of a fluid flow and the related instability that occurs in the annulus between differentially rotating concentric cylinders, most often with the inner cylinder rotating and the outer cylinder fixed, when the rotation rate exceeds a critical value. The stable base flow was used in the 19th century to test the fundamental … WebSep 7, 2010 · The thickness δ of the liquid film is determined by the ratio of to (the appropriate Reynolds numbers Re L and Re G) and by the shear stress τ i on the interface (related to the pressure gradient in a two-phase flow dp f /dx). The relation between δ, and dp f /dx is known as a triangular relationship.Given any two of the parameters, we can …
