Simulation study of jet trajectory based on Runge-Kutta method

Abstract

Abstract To solve the problem of not being able to accurately spray to the designated target point due to wind and distance factors when firefighting at a long distance, this paper adopts the Runge-Kutta algorithm to simulate the trajectory of the fire cannon, and establishes the mathematical model of the trajectory of the jet under the ideal state and the trajectory of the jet under the influence of the wind. We carry out three-dimensional visualization research and compare the results of the simulation experiment with the real experimental data, and the range, height, and trajectory have a high degree of fit. Comparing the simulation results with the real experimental data, the range and height of the jet and the trajectory have a high degree of affinity, and adding the wind power value panel in the visualization interface can simulate the changes of the jet trajectory under different wind speeds and wind power and effectively simulate the trajectory of the jet under natural conditions.
