Instability Wave Patterns from Harmonic Point and Line Sources in Laminar Boundary LayersThis paper presents the results of recent calculations of wave patterns produced by point and line harmonic sources in laminar boundary layers. It is shown that quasi-parallel stability theory can produce results that are in good agreement with experimental measurements in both the Blasius and rotating-disk boundary layers.作者: 個阿姨勾引你 時間: 2025-3-22 07:34 作者: agonist 時間: 2025-3-22 10:06
Development of Spatial Wave Packets in Boundary Layer waves are presented. A complex frequency-wavelength Fourier analysis of the data permits to study stability characteristics (including dispersive ones) for a fan of 3-D waves in a wide range of propagation angles.作者: 手術刀 時間: 2025-3-22 15:35 作者: Bernstein-test 時間: 2025-3-22 18:09 作者: Muffle 時間: 2025-3-23 01:17

Since 1973 many authors have investigated such nonlinear sets of splines functions, especially rational splines functions and obtained a lot of results.
