Analysis of the Added Mass of a Barge in Restricted Waters, Phase 2 Model

Abstract

A theoretical analysis of the added mass of barges in restricted waters is presented. The added-mass behaviors with varying waterway and barge parameters are predicted. A numerical technique is used to solve the potential-flow boundary-value problem. The analysis assumes that the Froude number is low. A restriction that the Froude number be less than or equal to 0.1 ensures that the surface waves will be small; this corresponds to a barge speed of 8fps (2.4 m/s). For this low-speed condition, the added mass is unaffected by the barge speed. The separation between the barge and the wall is seen to have influence near the wall.
