Turbulence concept is without doubt one of the so much fascinating components of fluid mechanics and lots of awesome scientists have attempted to use their wisdom to the improvement of the idea and to supply invaluable techniques for answer of a few sensible difficulties. during this monograph the writer makes an attempt to combine many particular techniques into the unified concept. the fundamental premise is the straightforward concept that a small eddy, that's a component of turbulent meso-structure, possesses its personal dynamics as an item rotating with its personal spin pace and obeying the Newton dynamics of a finite physique. a few such eddies fills a coordinate mobile, and the angular momentum stability should be formulated for this spatial mobile. If the mobile coincides with a finite­ distinction point at a numerical calculation and if the exterior size scale is big, this undemanding quantity may be regarded as a differential one and a continuum parameterization should be used. Nontrivial angular stability is a outcome of the asymmetrical Reynolds pressure motion on the orientated facets of an undemanding quantity. before everything look, the averaged dyad of pace elements is symmetrical, == even though, if averaging is played over the aircraft with common nj, the main of commutation is misplaced. hence, the tension tensor asymmetry j will depend on different components that perform the angular momentum stability. this can be the one risk to figure out a rigidity in engineering.
