Abstract Carboxymethylcellulose (CMC) and ultrasound gel (USG) seem to be suitable clear model fluids substitute real ultra-high-performance concretes (UHPCs), enabling experimental monitoring of events occurring within these mixtures at similar flow behaviour. USG is eligible for UHPC with significant yield stress. CMC having a concentration better UHPCs exhibiting indistinct The rheological b...

A jet-type magnetically driven fluid micropump to drive conductive fluids has been designed, fabricated, and tested. The pump actuation is based on a rotary magnetic micromotor with fully integrated stator and coils operating with the rotor immersed in the fluid to be pumped, thereby driving the fluid from a inlet flow reservoir through integrated flow channels to an outlet flow reservoir. The ...

In this work, a series of experiments and numerical simulations performed using volume-of-fluid approach were carried out to investigate the flow miscible viscous fluid systems through microfluidic focusing devices with one central inlet stream (with “fluid 1”) two lateral streams 2”). The combined effect viscosity ratio velocity on characteristics focused outlet was assessed in channels differ...
