Lomakin Effect & Swirl Break Rotor Dynamics Calculator

Calculate hydrodynamic centering Lomakin stiffness ($K_{xx}$) and cross-coupled destabilizing stiffness ($k_{xy}$) in multi-stage pump annular throttle bushings: size tangential swirl breaks and swirl-canceling honeycomb stator inserts, suppress destructive subharmonic fluid-induced rotor whirl ($0.45 imes ext{ running speed}$), and turbomachinery yields.
