    Exact Coherent State with Travelling Hairpin Vortex in Plane Couette Flow

    A new type of travelling wave solution is obtained in plane Couette flow. The solution appears via a Hopf bifurcattion from the so-called stationary hairpin vortex state found recently by [1] and [2]. The most...

    Linear and nonlinear instabilities of sliding Couette flow

    We consider an incompressible viscous fluid with the kinematic viscosity v between two infinitely long concentric cylinders with radii a and b (b > a). The fluid experiences a shear motion produced by pulling the...

    Study on Hyperactivated State of Coagulation and Fibrinolysis

    The excessive and untimely formation of blood clot(thrombus) in blood vessels may discontinue the blood supply to vital organ, and sometimes be followed by the aggravation of diseased state and the danger of l...
