Abstract

The valve is used on control of flow in a ship. Flow coefficient of valve is very importance in the design of valve. In this paper, three-dimensional computer simulations by commercial code CFX were conducted to observe the valve type and to measure flow coefficient when valves with various angles and uniform incoming velocity were used in a piping system By contrast, a group of experimental data is used to compare with the data obtained by CFX simulation to investigate the validity of numerical method.
