| Abstract: |
| The paper aims to explore the drag reduction performance and potential engineering applications of the superhydrophobic surface on the fluid flow in the ACP1000 cooling water pipe, numerically simulate the turbulent flow in the cooling water pipe , and study the flow characteristics of the turbulent flow in the cooling water pipe with a superhydrophobic surface inner wall. The superhydrophobic surface is simulated by alternating gas-liquid and liquid-solid surfaces, and the turbulent flow is simulated by a two-dimensional axisymmetric method. Numerical calculation result showes that with the increase of the gas fraction of the superhydrophobic surface, the skin-friction coefficient of the turbulent flow in the cooling water tube decreases; with the increase of the gas fraction of the superhydrophobic surface, the energy loss of the turbulent flow in the cooling water tube is reduced accordingly. Therefore, the application of superhydrophobic surface can optimize the flow performance of the cooling water pipes of the ACP1000 cooling system. This result provides a theoretical basis for further optimization of the cooling water system design of nuclear power plants in the future. |
