The effect of double-row wing bag sand barrier on wind prevention and sand fixation: wind tunnel simulation and field verification

Introduction: Most of the sand fixation technologies utilized locally and internationally are static or dynamic, making it challenging for a single mode to function in harsh environment. Therefore, development that combines resistance consolidation has emerged as trending topic control research. Our team developed wing bag barrier, which is dynamic combination mode. Methods: In this study, we examined characteristics airflow velocity field near double-row barrier under different wind conditions screen out optimal barrier. The analyses were conducted nine configuration modes through tunnel simulation experiment experiment. Results: inflection point was always 5H on windward side regardless speed. protection range with same specifications gradually weakened increase However, there an upward trend both total accumulation each height layer. When speed slower than 8 m/s, behind mainly concentrated 0–10 cm layer, when 12 30–60 At leeward particles rejected 0–30 cm; however, they cm. protective effect simulated consistent Discussion: For 6 recommended specification field-installed 25 × 20 30 at inlet m/s. greater cm,
