In order to predict the chemical agent dispersion in the complex urban area, numerical study on the thermal-flow characteristics in the vicinity of buildings were performed. In particular, methyl salicylate was adopted as chemical similitude agent. Right cylinder, regular hexahedron and regular four side pyramid shapes were applied. Numerical computations were carried out with the commercial code, CFX, which applied the finite volume method to solve the Navier-Stokes equations. With the help of the wind tunnel experiments, empirical formula was derived. The results could be used as the virtual test method of the real chemical agent dispersion.
