WAVE ANALYSIS ON SIMPLE HULL FORMS

A set of 2 m models are wave-analyzed. Importance is placed on the bow wave analysis (Part I) rather than in the resultant wave analysis (Part II). The Part I measured bow wave patterns show not only parallel shift but also the local distortion in co-ordination to the calculated wave patterns. Measured bow wave amplitude is found smaller than the calculated amplitude through certain ranges. The comparison among the three models tested shows that the linearized theory does not work so far as frameline effect is concerned. This may suggest some type of empirical correction factor. The Part II resultant wave analysis of bow and stern waves of Model M-8 shows Newman's truncation formula is not valid with one exception. The effect of finite transverse separation is of less importance than the truncation error. A discrepancy is observed between measured and calculated wave amplitudes of the transverse wave component. Besides viscosity effect, sheltering effect is supposed to be the cause for this discrepancy.
