Abstract

A three dimensional, finite element-based, flow and dispersion model is used to simulate the transport and fate of hazardous releases in the atmosphere. Numerical results are presented for two experimental studies: (1) Airflow and dispersion over multiple blocks in a wind tunnel; and (2) Tracer study of a point release in the neighborhood of a building complex. 1 Introduction Predictions of airflow and dispersion over urban areas continue to be a challenging problem because of the presence of extremely heterogeneous surface features within typical centers of population. For the case where atmospheric conditions are highly stable (low Froude number flows), th
