基于COMSOL的仓储粮堆内部自然对流和热湿传递的模拟研究 王远成 潘钰 尉尧方 鲁子枫 崔宏英 (山东建筑大学热能工程学院, 济南250101) 摘 要 本文基于仓储粮堆内部自然对流、热湿耦合传递的数学模型,采用COMSOL模拟的方法,探讨了仓储粮堆内部自然对流、热量传递和水分迁移过程的相互关系。提出了判断粮堆内部自然对流强弱的瑞利数及其影响因素,分析了仓型结构、粮种对粮堆内部自然对流、热量传递和水分迁移的影响。 结果表明,数学分析方法是分析仓储粮堆内部自然对流、热量传递和水分迁移过程的一种有效途径,数学分析的结果可以为仓型设计、储粮生态系统的模拟 ... Read More
在消费类音响产品中高音扬声器的设计品质 对于整个系统表现至关重要。主轴频响和可控的偏 轴指向性是设计的关键指标。利用VPD工具可以优化产品整体的声学性能,缩短研发周期,提 升效率, 和降低成本。从本质上来讲仿真是一种工具,不能 只停留在纸面上,需要做出样品与实际测量数据比 对,才能形成闭环,调整改善模型,参数和总结经 验,使仿真更贴近实际。 Read More
移动电话产品向更薄的趋势发展,装入手机中的微型扬声器能使用到的音腔空间也就日趋减少。为了高效利用手机内部空间,手机音腔设计时往往导通扬声器位置周围的小空间作为其音腔,扩大音腔体积。与此带来的问题是,因手机内部空间限制,导通管或导通孔规格较小,产生了声谐振效果。谐振频率点往往位于重要的中频段,使声压级中频段曲线出现波谷,影响声学性能和听感效果。 本文说明了声谐振产生的原因,并通过电力声类比,用理论方法估算出声谐振频率点的大致范围。为了解决声谐振产生的问题,我们使用 COMSOL Multiphysics® 准确模拟出扬声器声腔的 SPL 曲线,通过 SPL ... Read More
