Design of oxygen nozzle for oxy-propane gas cutting
Hanjie Xuebao/Transactions of the China Welding Institution(2012)
Abstract
According to the characteristics of oxy-propane gas cutting nozzle and the aerodynamic principles a software has been developed for oxygen nozzle design. Oxygen nozzle flow profile data and other parameters of oxygen flow would be calculated out by inputing several processing parameters. The paper presented an example of oxygen nozzle designed by the software tool. Computational fluid dynamics (CFD) simulation is employed to analyze the flow field characteristic parameters as the oxygen nozzle is working under the design pressure. Analysis of the distribution of oxygen jet flow velocity, mach number, and oxygen mass fraction have been carried out. The results show that the designed oxygen nozzle works and also indicate the correctness and reliability of the software.
