Abstract Conventional methods for the detection of bubbles uses probes which physically protrude into the flow field and thus may affect the flow dynamics, thereby tethering the formation, development and flow of bubbles. In thermal power plant, it is rather difficult to physically see which type of two phase flow is happening in the pipe. In such a case, an optical tomography sees its application. Depending upon the type of flow happening in a pipe, regulations of control valves are employed. This is necessary to avoid catastrophe. Some of the two phase applications lie in refrigeration systems, food processes and petroleum industries. Gas-solid flow is prominent in combustion of pulverized coal. Conventional methods for the detection of bubbles uses probes which physically protrude into the flow field and thus may affect the flow dynamics, thereby tethering the formation, development and flow of bubbles. The entire setup was covered in a 'Black Box' to prevent the interaction of other sources of light with the sensors. Our results show that the relative axial length of the Taylor bubble; which is the length of bubble at an offset distance from the axis of the vertical tube of constant cross section, is a constant and thus is independent of the length of the Taylor Bubble. This gives a promising result about the profile of Taylor bubbles. The variation of velocity of Taylor bubble was also studied with inclination angle by keeping the tube inclined to the horizontal line by an angle. Our study shows that the velocity increases to a maximum near 35 degree and thereafter decreases till vertical position.
