【摘要】：本文研究了具有超疏水潤(rùn)濕特性的磁流體座滴在均勻磁場(chǎng)作用下變形的數(shù)值模擬方法,采用實(shí)驗(yàn)結(jié)果對(duì)該方法進(jìn)行了有效的驗(yàn)證。研究中觀察的是水基磁流體座滴被磁場(chǎng)拉伸,座滴周圍充滿與其不互溶的礦物油,均勻磁場(chǎng)方向平行于基板表面。本文發(fā)展了問(wèn)題的數(shù)學(xué)描述,建立了多物理場(chǎng)模型,采用有限體積法對(duì)控制方程進(jìn)行求解,level-set方法對(duì)兩種不相溶的液體之間的界面進(jìn)行定義和追蹤,得到了不同磁場(chǎng)特性下座滴所具有的形態(tài)。
[Abstract]:In this paper, a numerical simulation method for the deformation of magnetohydrophobic droplets with superhydrophobic wetting characteristics under the action of a uniform magnetic field is studied, and the experimental results are used to verify the method effectively. It is observed that the water based magnetic fluid droplets are stretched by magnetic field, and the surrounding drops are filled with mineral oil which is insoluble to the water. The uniform magnetic field direction is parallel to the surface of the substrate. In this paper, the mathematical description of the problem is developed, the multi-physical field model is established, the control equation is solved by the finite volume method, and the interface between the two insoluble liquids is defined and traced by the level-set method. The morphology of the droplets in different magnetic fields was obtained.
