Abstract

3D numerical simulation is carried out to study the flow field of ship intake system in different inlet conditions. Results shows that the variation of total pressure and static pressure with inlet flow direction are approximately sinusoidal. The pressure fluctuation value of the front intake system is higher than that of the rear intake system. The angle between flow direction and shutter is bigger, and the flow field distribution at the shutter inlet is more uniform. The turbulence viscosity is higher at the rear intake shutters because of the flow separation, which leads to a worse inlet condition.

Key words
