Method for determining setting parameters of water curtain in liquid ammonia tank area of chemical enterprise

The invention discloses a method for determining setting parameters of a water curtain in a liquid ammonia tank area of a chemical enterprise. According to the method, on-site investigation and survey are carried out on ammonia-related enterprises, on-site data are surveyed, and computational fluid mechanics (CFD) boundary conditions such as wind direction, wind speed, air temperature and relative air humidity are determined according to local meteorological data; constructing a three-dimensional numerical model of liquid ammonia leakage diffusion according to a ratio of 1: 1; a proper grid division method is determined through grid independence verification, leakage working conditions before and after a water curtain is opened are simulated respectively, ammonia diffusion conditions under different working conditions are obtained, finally obtained results are compared and analyzed, and optimal water curtain setting parameters are determined. According to the method, the computational fluid dynamics (CFD) met
