We study oil-water flows in a Y-shaped rectangular cross-section microreactor with different parameters at each inlet. A theoretical model based on a Couette flow approximation is proposed and Navier-Stokes equation is solved for the relative movement in between oil and water plates. The model is further validated with preliminary measurements for flow profile reconstruction using optical feedback interferometry. The proposed method shows potential applications in assessment of immiscible flowing fluids
