Inhomogeneous turbulence beyond spectral equilibria: Aeronautical applications
Abstract
A spectral model of inhomogeneous turbulence is proposed. The simplified model is based on closure at two homogeneous points. The terms of inhomogeneous transport are expressed by means of a model based on one point of closure. The model is included in a finite element calculation code. Applications of the method to enclosed flow in aeronautical situations are proposed. Direct numerical simulation is carried out as a means of validating the method. The feasibility of a reference experiment is considered. Initial application to aeronautic calculations is performed.
