Abstract : The object of the research program was to gather a representative body of data on various groups of cylinders subjected to simulated wave action with a vien to providing information relative to the behavior of docks, dolphins or other marine and harbor structures of similar configuration in waves of various heights and periods. The main body of data was taken by an inverted model study in which the horizontal component of the orbital motion of the water caused by wave action was simulated by moving vertical groups of cylinders through otherwise still water in a rectilinear oscillatory motion parallel to the water surface. The forces measured were principally drag, lift (transverse force) and moment of the group about a vertical central axis. Correlations of the data for the various groups were sought with emphasis on the validity of modelling the waves by Froudes law and the force coefficients by Reynolds law. (Author)
