Liquid distribution machine has an important role in industry, which pressure drop as well as flow distribution be simultaneously improved. In this paper, a multi-objective design optimization for minimizing the standard deviation of liquid flow and the pressure drop is performed using numerical simulation. Numerical simulation in computational fluid dynamics (CFD) is so intensive that sequential approximate optimization using radial basis function is adopted for the design optimization with a small number of simulations. Through the numerical result, the pareto-frontier between the standard deviation of liquid flow and the pressure drop is clarified. In addition, it is confirmed that the angle of perforated plate reduces vortex which have a significant influence on the flow maldistribution.
