The aim of this work is to broaden our knowledge of the behavior of Taylor bubbles in a coflowing liquid inside flat microchannels with a high aspect ratio. The primary focus is put on the near-wall region, which is difficult to study both experimentally or numerically. The investigated quantities are the thickness of a liquid film separating the bubble from the microchannel wall, wall shear stress induced by the bubble movement, and the shape and velocity of the translating bubble.
