Abstract

Low resistance and good hydrodynamic properties are one main purpose of a submerged object design. The fore body is a major concern because it not only serve as a space for laying an acoustic equipment, but it determines the flow toward the hull. Steady RANS simulation was conducted to examine the influence of the bow shape to the surrounding flow on submerged projectile-shaped object without appendages or propulsion. The fore body is varied based on the Hull Envelope equation. The result shows the model with nf=2.75 is the optimum design according to the hydrodynamic efficiency coefficient despite the model with blunt form (nf=1) has a lowest drag because it has smallest wet surface area. Pressure coefficient distribution on the fore body span and the pressure.
