• Advective diffusion analyses have been applied to many fields of science and engineering, such as dispersion of chemically reacting substances, thermal conduction in fluid, electromagnetic field by a moving magnet, and migration of nuclides in groundwater flow. In solving non-static advection diffusion equations by the boundary element method, however, time integrations appear in the boundary integral equation, which makes the BEM application to advection diffusion problems difficult. Therefore, the method has been approximated in the past relevant publications. This paper describes the method to carry out the time integrals analytically, and the usefullness of the technique is demonstrated with some examples of practical engineering interests. The results obtained from the examples were compared with the analytical solutions or with the results from other numerical codes.
