燃油粘度与环境压力对喷雾碰撞过程的影响(Investigation of the Influences of Droplet Viscosity and Environmental Pressure on the Spray Collision)
内燃机 喷雾模拟 碰撞模型
2010/12/28
O’Rourke碰撞模型仅仅考虑了碰撞拉伸分离以及聚合,而忽略了碰撞反弹、反射分离以及高韦伯数下的碰撞二次破碎过程,在碰撞分区过程中也忽略了燃油物性以及碰撞环境条件的影响,使得预测的碰撞分区临界韦伯数偏低。复合碰撞模型根据相关的实验结果对碰撞分区进行油滴粘度以及碰撞环境压力修正,考虑碰撞反弹、反射分离、拉伸分离以及碰撞二次破碎过程,提高了碰撞分区的预测精度。基于复合碰撞模型,分析了油滴粘度与环境压...
温室环境控制与温室模拟模型研究现状分析(Review on Environmental Control and Simulation Models for Greenhouses)
环境控制 温室 模拟 数学模型
2009/8/11
综述了温室环境控制系统、控制策略及环境模拟等研究领域的发展状况。目前温室环境主要采用多处理器的分布式控制系统,控制器以结构通用、价格便宜的单片机为主,也可应用工业控制器,但工业控制器的价格较高。环境控制的研究重点是控制系统的智能化和信号传输的无线化,无线传输适合温室特点,为现场布线及后期维护带来方便。通过模拟模型可以了解结构特征、气象条件及作物生长等对温室环境的影响。综合考虑环境因子、作物生长及经...
