  7. Abstract:
  8. Release of toxic gases and hazardous materials is very dangerous for health of people that presence in near of release places. Whereas if the concentration of some toxic materials is more than a definite limit, it may cause of irreparable hurt to health of people in very short times, hence reduce the concentration of released materials can get the time for refuge in safe sites for people that presence in released site in initial times.
    In this paper with use the Computational Fluid Dynamics models the effect of fence in reduce the concentration of dense gases and delay the distribution of these gases has been studied. The two toxic gas (chlorine and methyl-isocyanate ) have been considered that both gases are denser than air. The effect of fence in dilution of these gases has been studied. Also the effect of other factors such as wind velocity and location of fence in reduce the concentration and delay the distribution has been studied. Results are show that whatever wind velocity is lesser and location of fence is near to the release spot, set of fence to reduce the concentration and also to delay the distribution is more effective. Also efficiency of CFD models for simulation of various cases of dispersion has been studied
