WebFeb 27, 2014 · Fluid turbulence is often referred to as `the unsolved problem of classical physics'. Yet, paradoxically, its mathematical description resembles quantum field theory. The present book addresses the idealised problem posed by homogeneous, isotropic turbulence, in order to concentrate on the fundamental aspects of the general problem. WebEstablishing such a general theory is a 'grand challenge' to modern science. The present work describes a statistical theory concerning a certain class of nonlinear, finite dimensional, dynamical models of turbulence.
