Simulation Study on Contaminant Source Identification
Jun Wang · Jisuanji fangzhen · 2010
In case of contaminants appear in enclosed spaces such as spacecraft,submarine,aircraft and so on,it is useful to find the contaminant source. A novel algorithm was proposed to identify contaminant source strength based on finite sensors. After having identified the source location by using the Sensitivity Analysis Algorithm (SAA),this method built a new discrete concentration stochastic model,and combined implicit and explicit Kalman filter. Monte Carlo simulation was used in our experiment. The simulation results show that the new method could track and predict the source strength dynamically; meanwhile,it also could predict the distribution of contaminant concentration.
