膜阀微流道液流脉动消减性能
Flow Pulsation Reduction Performance in Microfluidic Channel of Membrane Valve
摘要
Abstract
Propose a method of actively reducing liquid flow pulsation in liquid microchannels of microfluidic chips using on-chip membrane valves.Taking the valve chamber accumulator and valve chamber damping hole as the research objects,the ANSYS Fluent UDF custom simulation method was used to study the reduction performance of liquid flow pulsation in the micro channel of the membrane valve.Results shown that the reduction effect of different structural reduction elements is different,and the reduction effect varies with the number of membrane valves.Based on the working principle of pulsation reduction elements,liquid flow pulsation reduction experiments were carried out.The experiment shows that the active reduction method of liquid flow pulsation in microfluidic channel based on membrane valves is an effective verification of the rationality of the liquid flow reduction element in microfluidic channel based on membrane valves,the correctness of the theoretical model,and the feasibility of specific applications.It provides theoretical guidance and technical support for precise control technology of micro liquid flow rate.关键词
