Numerical Simulation for Thermodynamical Processes of Internal Combustion Rock Drills

This paper introduces the research work for years about numerical simulation to the operating processes on internal combustion rock drills (ICRD). The thermodynamical processes in gas chambers and insteady flow in the slant pipe were discussed, including establishing the model, basic equations, calculating principle and computing results. The calculated results were satisfactorily close to the measured values. The successes of numerical simulation for operating processes on ICRD offer a powerful tool for revealing its operating mechanism, predicting performance and optimizing parameters.
