Combining this relation with the budget equation for the turbulent kinetic energy we obtain the “equilibrium formulation” of the turbulent dissipation length scale, and recommend it for use in turbulence closure models.</style></abstract><auth-address><style face="normal" font="default" size="100%">NERSC</style></auth-address></record></records></xml>
