What Is the Taylor-Couette Vortex Instability & Taylor Number Calculator?
Taylor-Couette flow arises in the fluid annulus between two concentric cylinders when the inner cylinder rotates while the outer remains stationary.
Above the critical Taylor number (Ta_crit ≈ 1708 for narrow gaps), centrifugal forces overcome viscous damping, triggering secondary counter-rotating axisymmetric toroidal vortices known as Taylor vortex cells.
How Does the Taylor-Couette Vortex Instability & Taylor Number Calculator Work?
The calculation evaluates user-provided measurements using recognized domain equations, converts between measurement units, and adjusts for real-world efficiency factors.
