矩形养殖池刮板排污装置的设计优化与验证OA

This study addresses the challenge of efficiently removing bottom solid waste in intensive aquaculture tanks by focusing on rectangular aquaculture tanks.A two-dimensional transient model,coupling the standard k-ε turbulence model with the VOF free surface model,was developed to optimize a mechanical scraper discharge system.Using an L25(53)orthogonal design,the effects of scraper height(6-14 cm),tilt angle(-20°-+20°),and speed(0.05-0.09 m/s)on particle distribution and discharge efficiency were analyzed.The results showed that the tilt angle had the most significant impact,with the optimal parameters being 6 cm height,+10° tilt,and 0.05 m/s speed,achieving the highest efficiency and minimal residue.To validate the numerical model,45 single-factor tests were conducted on a physical platform using particle recovery to quantify removal efficiency.Results deviated by only 5％-10％from simulations,confirming model accuracy.The study supports the engineering optimization of mechanical scraper systems.
