电磁场驱动下的液体流动实验与模拟研究
|
摘要
计算流体力学作为经典流体力学、数值分析方法和计算机技术的有机结合体,近年来,得到不断发展和壮大,成为科研和工程设计的有效手段。理论、实验和模拟三者相互渗透,既推动了流体力学理论的新发展,同时也加强了流体力学的工程应用。
从电场和磁场当中导电的液体受力出发,分析了电解质溶液在电磁场中的驱动与运动,根据电磁驱动模型,针对被驱动流场中微观粒子图像测速技术进行研究,并设计了流体多尺度下的驱动显示实验装置,进行了测试。
首先,分析电解质溶液在电磁场中驱动的机理,建立出理想条件下的数学模型,归纳液体在电磁力驱动下的运动方程,得到电场和磁场与运动的关系。
其次,自行研制不同材料与结构的电磁场驱动电解质溶液的实验装置,采用图像分析与转换技术研制设计出“宏观与微观尺度下”的电磁驱动液体流动观测实验装置,通过激光光源的改进与在流场显示中的应用设计,提出流场内粒子的“微观”显示与测速方法,得到流场的图像和数据等。
然后,使用有限元法对通道内的液体流动进行分析,应用ANSYS软件建立数值模拟模型,获得电磁场驱动下的流场运动分析结果。
最后,对比实验数据及数据分析与数值模拟结果可知,电磁场驱动下的流体运动规律。并为电磁驱动液体流场中,不同深度内的粒子流速的测量提供了一种测量手段。
As the organic the body combination of a classical fluid dynamics, numerical analysis methods and computer technology, recently, computational fluid dynamics becomes stronger, and is the efficient methods of both science research and engineering design.
Based on the stress of liquid in EMF, we analysis drive and motion of electrolyte solution in EMF. According to the electromagnetic drive model, we made study on microscopic DPIV in driven flow field, and multi-scale of driven design display unit of flow field.
First, we analyzed the principle of the electrolyte solution propelled in electromagnetic field, set up a mathematic model on the ideal condition, instructed a motion equations of the liquid propelled by both direct and alternating current, and then received the relations between EF/MF and motion.
Second, self-developed materials and structure of experimental installation for electrolyte solution drive by electromagnetic of field different, use image analysis and conversion techniques to design experimental installation of electrolyte solution drive by electromagnetic“in Microscopic and Macroscopic Condition”. With improvement of LASER source and indication application in flow field, we put forward“micro display”light engine of particle in flow field and method of measuring speed, and then we get images and data of flow field.
Third, we analyzed the liquid in passageway with finite element method, set up a numerical simulation model by ANSYS, and got the results of EMF driven by Flow Motion Analysis.
Finally, we compared experimental data and data analysis with numerical simulation to get motion law of ghost fluid in driven magnetic field. And supply a method to measure particle’s velocity in different depth of flow field where liquid is driven by EMF.
