AN OVERVIEW OF THE REDIPHEM PROJECT

The Commission of the European Communities has been funding research p rojects to develop an understanding of chemical and physical phenomena related to industrial hazards, such as toxic and flammable releases a nd explosions. These projects result in predictive models and experime ntal data. To make these models and data available for a wider communi ty and to judge their areas of application, the REDIPHEM project (REvi ew and DIssemination of PHysical Effect Models) was started. This proj ect covers two topics: heavy gas dispersion and source terms. This pap er describes the activities and status of REDIPHEM. Moreover, it addre sses the problems related to the design of a statistical validation ex ercise for heavy gas models.
