The Batchelor Spectrum for Mixing of Passive Scalars in Isotropic Turbulence Academic Article uri icon

abstract

  • We examine the support for the Batchelor spectrum from well-resolved simulations of high-Schmidt-number mixing in isotropic turbulence, and resolve a conundrum with respect to the numerical value of the prefactor, also known as the Batchelor constant. Our conclusion is that the most probable value of the most compressive principal strain rate is more relevant than its mean, at least asymptotically. © 2010 Springer Science+Business Media B.V.
