Étude des régimes thermohydrodynamiques du procédé d'oxycoupage assisté par laser

Abstract : Oxygen-assisted laser cutting is a widely used processed. It is well-known for its high efficiency in both the cutting speed and quality. Nonetheless, this technique requires highly secured closed environments. Currently, the dismantling industry sees this process as a way to replace more traditional cutting techniques such as blowtorches or pliers. However, to be used in such fields, the security setup needs to be less constraining, hence the energy source power is limited. This study aims at efficiently reducing the energy requirements through a better understanding of thermodynamics phenomenon as well as a deeper comprehension of the physical phenomenon driving the process. This work showed that the combustion can be initiated in solid phase and the temperature of the liquid phase during cutting process is about 2150K.
