Modified Navier Stokes Equation and new Law of the Wall for Turbulent Flows in Flat-Plate Systems
Original language description
It is well known that in a turbulent flow between two parallel flat plates, the horizontal mean velocity varies logarithmically with height (the so-called 'log-law-of-the-wall'). The law of the wall is a description of the mean velocity profile in wall bounded flows and has been regarded as one of the underpinning doctrines in the turbulence community for more than half a century. Much of our understanding in wall turbulence has been based on the continuum Navier-Stokes equation. More recently, following studies with a post-Navier-Stokes equation [1], we apply a modified Navier-Stokes equation to the flow of turbulent fluid between two parallel flat plates. We extend the analysis to the turbulent flow along a single wall and compare the results with the established controversial von Karman logarithmic law of the wall [2] and the Barenblatt-Chorin power law [12]. We find velocity profiles and velocity time evolution of a turbulent system that cannot be reproduced from the classical Navi
