Abstract The main objectives of this study are improving snowplow truck operator's visibility, especially under heavy and deep high speed snowplowing (HSSP), and explore the means of reducing or completely eliminating engine overheating due to snow blocking the air flow to radiator. During HSSP, snow (from roadways) may overflow the moldboard, and can cause snow accumulation on truck windshield that reduces snowplow operator's visibility. Snow overflowing the moldboard can also cause snow and ice accumulation on engine radiator grille that originate engine overheating problem by blocking the airflow to radiator. Research and studies are carried out to solve the problems of State of Nevada Department of Transportation (NDOT) snowplow trucks. Computational Fluid Dynamics (CFD) studies are utilized to design a moldboard overplow deflector. Snow particles are computationally studied using the Discrete Phase Modeling (DPM) to analyze their trajectories after particles bounce back from the plow moldboard and truck. Resulting deflector is manufactured and it is mounted over the moldboard of one of the NDOT Trucks serving the Mount Rose area in western NV. Field tests, and experiments were promising and showed considerable reduction in snow accumulation on the engine grille, and truck windshield.

使用计算和实验方法提高扫雪安全性和效率：扫雪车的前端

摘要 本研究的主要目的是提高扫雪车操作员的能见度，特别是在重型和深度高速扫雪（HSSP）下，并探索减少或完全消除由于雪阻塞空气流向散热器导致的发动机过热的方法。在 HSSP 期间，雪（来自道路）可能会溢出刮土板，并可能导致卡车挡风玻璃上积雪，从而降低扫雪机操作员的能见度。溢出刮土板的雪还会导致发动机散热器格栅上积雪和结冰，从而通过阻止流向散热器的气流而导致发动机过热问题。开展研究和研究以解决内华达州交通部 (NDOT) 扫雪车的问题。计算流体动力学 (CFD) 研究用于设计犁刀板超犁偏转器。使用离散相建模 (DPM) 对雪粒子进行计算研究，以分析粒子从犁式犁板和卡车弹回后的轨迹。最终的导流板被制造出来并安装在其中一辆 NDOT 卡车的犁板上，该卡车为内华达州西部的玫瑰山地区提供服务。现场测试和实验很有希望，并表明发动机格栅和卡车挡风玻璃上的积雪显着减少。
