| Abstract: | The important meaning of study on leakage model and discharging dispersion simulation for gas pipeline to accident consequence evaluation and accident treatment of pipeline leakage was analyzed. The steady and transient calculation models for gas pipeline were summarized, and the applicable extension was indicated. Discharging dispersion simulation models and their characteristics for gas pipeline were presented. Establishing simple simulation models, simulating with 3- D models and turbulent statistics theory and turbulent models theory were proposed. |
