Single Optical Fiber Probe for Structured Bed
A single optical fiber probe technique has been developed to be used in structured bed such as monolith to monitor and measure inside various channels the liquid and gas velocities, their holdups and flow regime and patterns.
The single fiber probe is a modified version of the four point optical probe technique which has been used in bubble columns to measure gas hold up, bubble size and other characteristic parameters of two phase flow and three phase flow systems. The single fiber probe works on the same principle as outline under the four point optical probe. In our laboratory the single fiber probe has been developed to and used in structured beds such as monolith reactor to monitor and measure inside various channels the liquid and gas velocities, their holdups and flow regime and patterns The major advantage of this technique is that the phases do not have to be conductive.
