Optimization of Dangerous Heavy Gas Leakage and Diffusion Model Algorithm

TL;DRAbstract

On the basis of research status from both at home and abroad and in view of the leakage diffusion of heavy gas stored in pressure vessels, this paper selects the heavy gas diffusion's Heavy Gas Dispersion Model in Laminar and Turbulent Atmosphere Laminar and Turbulent Atmosphere environment of Heavy Gas Dispersion Model model and multipuff Gaussian model to calculate the total amount of dangerous gas leaking from the pressure vessel into the environment based on the leakage calculation model and calculate the density of gas cloud real-timely with comprehensive consideration of time, wind speed, atmospheric stability, geographical environment and other environmental parameters.This paper aims at optimizing model algorithms to improve the model calculation speed by introducing OpenMP shared memory parallel programming under multiple CPU cores, thus calculate real-timely the density of heavy gas clouds.
