A Note on Similarity Solutions of Navier-Stokes Equations
《Communications in Theoretical Physics》2010年第3期575-578,共4页K. Fakhar T. Hayat CHENG Yi N. Amin 
This note looks at the two similarity solutions of the Navier-Stokes equations in polar coordinates. In the second solution an initial value problem is reduced into generalized stationary KDV and hence integrable.
