Marquage moléculaire

Project

Context:

Mass transfer between a gas bubble and a liquid phase is involved in many industrial situations. Despite its many applications, the fundamental mechanisms of this transfer remain poorly understood because of the complex and local nature of the phenomena and the lack of experimental data. The aim of this project is to implement an original optical method allowing for the simultaneous measurement of both the liquid phase velocity and the pH, leading to the dissolved gas concentration.

Goals: Simultaneous, local and multi-point measurement of liquid phase velocity and pH.
