초록

The Firefighting Monitor is essential for large-scale firefighting, but the reaction force generated during high-pressure water discharge poses control challenges. In robotic control systems, reaction forces can reduce the precision of spraying operations. In this paper, we aim to determine the optimal design of decompression equipment to mitigate reaction forces in nozzles. Three configurations (None, Orifice, and Airfoil) were designed and evaluated using Computational Fluid Dynamics (CFD) simulations. The results demonstrated that the Airfoil shape exhibited the lowest upward reaction force and superior performance in terms of reaction force reduction under four inlet pressures and both at 0° and 45° conditions. The Airfoil shape was identified as the most effective in reducing reaction forces and improving flow stability.
