摘要:
利用正交实验设计法，对16种不同尺寸的微流控芯片进行微滴生成的数值模拟研究，并使用理想解法对仿真结果进行综合分析。探究一种单个液滴生成周期短，消耗连续相试剂量小，加工成本低的微流控芯片。结果表明，当连续相通道尺寸为40μm，离散相通道尺寸为30μm，十字出口通道尺寸为25μm，通道深度为20μm时可以得到最优尺寸结构的微流控芯片。
Abstract:
This study aimed to explore a microfluidic chip that could generate a single droplet with a short cycle,consume a small amount of continuous phase reagents,and have low processing costs.The FLUENT simulation and VOF method were employed to simulate 16 microfluidic chips with different structure sizes in orthogonal experiments.Finally,the TOPSIS was used to comprehensively evaluate the numerical simulation results,and the order of superiority and inferiority of 16 structures was obtained.The evaluation results showed that a microfluidic chip with the optimal size structure could be obtained under the conditons of the continuous phase channel size was 40 μm,the discrete phase channel size was 30 μm,the cross exit channel size was 25 μm and the channel depth was 20 μm.The microfluidic chip could be produced the performance with smaller droplets,highest frequency and consumes less continuous phase reagent per unit time.
