Modeling and numerical analysis of hydrodynamic characteristics of three-dimensional slotted airfoils
摘要
Abstract
Aiming at the unclear hydrodynamic characteristics of three-dimensional slotted airfoils in underwater environments and the difficulty in directly applying existing aviation slotted designs,this paper conducts modeling and numerical analysis of their hydrodynamic characteristics.As a design to improve fluid dynamic performance by adding slots or openings on the airfoil,three-dimensional slotted airfoils are widely used in aviation to enhance lift and delay stall.However,considering the differences in density and viscosity between water and air,the underwa-ter flow mechanism differs significantly from that in air,so the application effect of three-dimensional slotted air-foils underwater needs urgent re-evaluation and optimization.In this paper,the Reynolds-Averaged Navier-Stokes(RANS)method is adopted.We adjust the position of slot curves through programming,establish three-dimensional models with different parameters using Creo software,and conduct detailed numerical flow field calcu-lations on the STAR-CCM+platform.Intensive grid refinement and grid convergence analysis are performed to en-sure the accuracy of computational results.We investigate the effects of different angles of attack,slot positions,widths,and slopes on the lift-drag ratio.The results show that rational optimization of these parameters can effec-tively improve the lift-drag ratio of three-dimensional slotted airfoils.This work provides crucial theoretical guid-ance and practical references for the design of efficient underwater slotted airfoils.关键词
