Abstract

This paper investigates the acceleration resistance of a vessel in shallow waters
using potential flow and CFD methods. Results indicated a pronounced resistance peak near the critical depth Froude number. The peak's location and magnitude were sensitive to acceleration intensity and water depth. Excellent agreement between potential flow and CFD methods was found in low and high depth Froude number ranges, suggesting their effectiveness and cost-efficiency. However, non-linear effects affected the resistance peak's magnitude and position, leading to slight disagreements between the methods. The solver's variation was observed to be sensitive to the investigated parameters.
