Abstract

In this paper, decoupled form of CFD methods considering important design parameters is applied to model and predict the surface flow on fluids. Application of Coanda-effect on-going trends of particle removal methods for determination and prediction of cleaning performance in a camera lens is a new research area due to its significant role in design, evaluation and optimization. Numerical analysis of cleaning performance in term of particle drag force coefficient of nozzle and energy efficiency is carried out for surface radii, cover lengths and angle of attack. Furthermore, an optimization method for achieving optimal particle cleaning is presented. The optimization problem is formulated based on independent variables including lens surface radius r, camera cover length l1and l2, and angle of attack qwith the objectives to maximize pressure flow and drag force coefficient while minimizing the dynamic turbulence flow. To establish this condition, a novel design of particle removal is introduced and simulation study is carried out in FLUENT to investigate the growth and the structure of surface disturbances on a flat and curved surface by a coaxial airflow in accordance with the pressure distribution and shear stress. And the genetic algorithm in I-SIGHT is used to obtain optimized particle removal for camera cover design. A method to apply the optimization results for optimum particle drag forces ability is discussed.
