Description: Technical Memorandum
From the Introduction: This report contains two main results. In the first section an exact mathematical solution is presented for the linearized problem of water waves of small steepness incident on a circular cylinder. The fluid is assumed to be frictionless and the motion irrotational. This section includes, in addition to the formal mathematical treatment, some simple deductions based on the assumption of very small ratio of cylinder diameter to incident wave-length. The principal results of the theory are summarized, for convenience in calculations, in the second section. Also presented are some suggestions as to possible extensions of the theory to take care of more extreme wave conditions and other obstacle shapes. The second result is an attempt to apply the theory to the computation of actual wave forces on cylindrical piles. The basis of this comparison is a series of tests performed in the wave channel. The agreement is found to be quite good in the region in which the assumptions of the theory are fairly closely realized.
