Study on resistance characteristics of orifice-labyrinth hybrid restrictor based on central composite design method

This data is for the paper, including grid independence data for numerical simulation of throttling elements; comparison data for different turbulence models; comparison data for different y-plus values; data on internal pressure and flow velocity of throttling elements; data on pressure drop with plate spacing, number of orifice plates and baffles, and diameter of orifice plates; independent and mutual effects data of throttling elements; and response surface data. The data used for verification comes from the water circuit experimental bench of the University of South China.
