WAKE ANALYSIS OF SHIP MODELS TWIN-SCREW MERCHANT TYPES

摘要

This report, the fourth in a series on studies of the wake in the propeller plane of ship models, presents the results of the wake of twin-screw merchant-type ship models using the IBM-7090 computer. The data presented are the inter¬polated longitudinal and tangential velocity distributions, their computer mean values, the harmonic contents of these velocity components, the maximum varia¬tions in the resultant inflow velocity, and the advance angles and their variations. Also included are the calculated volumetric wake velocities.
