Abstract:

Simple formulas are presented with which the inviscid surface pressures at low frequencies can be rapidly calculated. It is also shown that for small amplitudes, the error introduced by omission of higher-order terms in frequency is generally less than 1 for reduced frequencies as high as 0.3. Author
