WebDec 29, 2024 · In this paper, we derive scaling laws and obtain self-similar velocity defect and Reynolds stress profiles for the outer part of three-dimensional wall jets in the high-Reynolds-number limit. The scaling laws are derived from prime principles under realistic assumptions about the behavior of the flow. We show that the leading term in an ... WebThe scaling and squaring method for the matrix exponential is based on the approx-imation eA ≈ (rm(2−sA))2 s, where r m(x) is the [m/m] Pad´e approximant to ex and the integers m and s are to be chosen.
