WebFor analysis purposes, there are some similarities between the marine propeller as a noise source and airplane propellers. A marine propeller can, for the purposes of noise prediction, be considered as a compact noise source since the product of the wave number times the radius is much less than unity. WebMay 13, 2024 · The propeller acts like a rotating wing. From airfoil theory, we know that the pressure over the top of a lifting wing is lower than the pressure below the wing. A spinning propeller sets up a pressure lower than free stream in front of the propeller and higher than free stream behind the propeller. fishing swivels new zealand
