Asymmetric turbulent flows
Abstract
Free and wall turbulent asymmetric flows generated as soon as unequal boundary conditions exist are described. Their main characteristic is the difference which occurs between the location at which the mean velocity (or mean temperature) reaches an extremum and the location at which the turbulent momentum (or heat flux) changes its sign. The subsequent counter-gradient transfer or energy reversal is discussed. Advanced closures which give acceptable results in most cases are introduced.
