Project

Development of a new methodology using CFD-based tools for a better assessment of accident effects in QRA

Host organization

UPC

Supervisor

Prof. Eulàlia Planas (UPC)

Duration

36 months

Objectives

The main objective of this project is to develop an original easily operated methodology to assess major accident effects employing CFD in QRA studies. This methodology will include the guiding principles to study dispersion, fire, and explosion effects by CFD models with a particular focus on open-source tools.

The values obtained will be checked by comparison with selected and liable data from real accidents. Special attention will be paid to the Hydrogen case study to model the accidental scenarios that can occur during hydrogen production and liquefaction.

Expected results

An improved methodology in which the guiding principles for CFD correct use in QRA of major accident scenarios will be included. It will allow a more realistic prediction of accidents’ effects, overcoming the actual lack of precision of classical modeling techniques when applied to the complex scenarios associated with process plants. It will also help to build a cause-consequence database.
