摘要
A diffuser/nozzle pair serves as a flow rectifying element in a valveless micropump, which is one key component in microfluidics devices. This paper proposes a diffuser/nozzle element with extended sidewall, 'lip', at the diffuser's large opening end. This novel structure is based on the fluid mechanism concept that an extended sidewall introduces extra entrance pressure loss, which is preferred in the nozzle direction. A clear improvement in efficiency is observed in both the numerical and experimental results.
