The shape of a Taylor bubble in a vertical downward slug flow in a pipe is studied. The phase distribution in the Taylor bubble region is investigated by still pictures and video film. The shape of the Taylor bubble is reported for different condition. These experimental results consists of the position of the interface x(r) obtained using image processing and represents the new view to the shape of the Taylor Bubble and gives some light on the basic phenomena for the hydrodynamics of the two-phase slug flow. Slug flow is one of the most common and complex flow patterns in two-phase flow. Slug flow exists over a broad range of gas and liquid flow rates and is encountered in a wide variety of industrial applications like gas wells and process vaporizers. It also occurs during certain stages of emergency core cooling of a nuclear reactor.
