We have shown by machine proof that F24 = 2224 + 1 is composite. The rigorous Pepin primality test was performed using independently developed programs running simultaneously on two different, physically separated processors. Each program employed a

Results are presented for a class of self-similar solutions of the steady, axisymmetric Navier–Stokes equations, representing the flows in slender (quasi-cylindrical) vortices. Effects of vortex strength, axial gradients and compressibility are stu

Evidence is presented for what appears to have been nonmodal disturbance growth in a pipe‐flow experiment performed by Kaskel [Technical Report No. 32‐138, Jet Propulsion Laboratory, California Institute of Technology, 1961], based on a compariso

Results are presented for a new class of selfsimilar solutions to the steady, axisymmetric Navier-Stokes equations, modelling the flows in vortices whose viscous cores grow proportionally to an arbitrary power of the axial coordinate. Effects of Reyn

The linear stability of the trailing line vortex model of Batchelor (1964) is studied using a spectral collocation and matrix eigenvalue method. The entire unstable region in the swirl/axial wavenumber parameter space is mapped out for various azimut
