Dynamics of isolated confined air bubbles in liquid flows through circular microchannels: an experimental and numerical study

John Richard Thome, Navid Borhani, Mirco Magnini, Sepideh Khodaparast

Experimental and numerical studies are performed to characterise the dynamics of isolated confined air bubbles in laminar fully developed liquid flows within channels of diameters d = 0.5 mm and d = 1 mm. Water and glycerol are used as the continuous liqui ...

Application of micro particle shadow velocimetry mu PSV to two-phase flows in microchannels

John Richard Thome, Navid Borhani, Sepideh Khodaparast

Micro particle shadow velocimetry (mu PSV) is performed in the present study for simultaneous velocity measurement and interface tracking in both liquid-liquid and gas-liquid two-phase flows through circular microchannels of 5001 mu m diameter. The back-li ...

A micro particle shadow velocimetry (mu PSV) technique to measure flows in microchannels

John Richard Thome, Navid Borhani, Giulia Tagliabue, Sepideh Khodaparast

A micro particle shadow velocimetry (mu PSV) system based on back-lit illumination and forward scatter observation of light from non-fluorescent particles has been developed. Relatively high luminous efficiencies and particle image contrasts were achieved ...

Sudden expansions in circular microchannels: flow dynamics and pressure drop

John Richard Thome, Navid Borhani, Sepideh Khodaparast

Micro particle shadow velocimetry is used to study the flow of water through microcircular sudden expansions of ratios e = 1.51 and e = 1.96 for inlet Reynolds numbers Re (d) < 120. Such flows give rise to annular vortices, trapped downstream of the expans ...
