“…With this procedure, we introduce ghost Reynolds numbers [34] for each moment order larger than one. Hence with the scan over the parameter space induced by bold-italicς, we test values of possible ghost Reynolds numbers, which in terms of (3.11) appear as controllable bulk [64] and hyper viscosities [37,40]. Based on that, three-dimensional BF-stability maps are obtained and gathered in figure 5, where the x-, y-, z-coordinate axes correspond to ςq,μ, ςe, ςε,Π, respectively.…”
