This study introduces a novel splitting distributor design to achieve uniform gas–liquid flow distribution in parallel microchannels. The comprises channels that sequentially reduce width by factor of half and wedge/flow-focusing geometric modifications at the junctions facilitate efficient dynamics bubbles. present confirms this configuration promotes symmetric achieves all effectiveness is evident low maldistribution (MDF) values, typically below 0.1. uniformity most silicone oil–air systems where MDF values are 0.06, even high continuous phase velocities. Additionally, examines impact fluid properties (viscosity, surface tension, density) on pressure drops testing five different systems: keeping dispersed as air, phases water+SDS solution, oils (5 10 cSt), kerosene, blue dye+SDS solution. It seen significantly enhance bubble-splitting efficiency for systems. with increasing capillary numbers (Ca) systems, gas bubble lengths decrease, two-phase escalate, highlighting dynamic interplay under conditions. These findings will guide future research developing evaluating innovative designs various application-specific
