“…The plane sound wave in a space filled with moving from the right to the left (against x-direction) medium with averaged Mach number M and limited from the left by plane 0 x  on which the acoustic source specified by (5), and on the right by an acoustically perfect reflecting plane xL  is considered. The wave equation (1) in this case is simplified to the form:…”

“…These issues in the developed world receive increasing attention, which is reflected in a significant tightening of the requirements for limiting the noise level in accordance with ISO standards [1,2] . Numerical modeling of the computer cooling fan acoustics becomes an engineering problem of current interest [3] as well as for train fans [4] and modern aircraft turbofan engines [5].…”

“…This is because the traditional guide vane is fixed on the guide vane hub with a fixed angle for the design condition and cannot be adjustable with the change in working conditions. The literature on OGV investigations for aircraft engine mainly falls into the following categories: effects of OGV on aircraft engine's noise [2][3][4], unsteady interaction between the stationary OGVs and the rotor [5], and flow characteristics of OGVs [6][7][8][9].…”
