Abstract
Fire models are used increasingly for fire safety assessment in nuclear power plants.

Examples of these fire models are CFD models and zone models. When using these

models it is important that they are sufficiently verified and validated. In Sweden the

majority of fire safety consultants are using FDS, developed by NIST. The verification

and validation of this package is intensively done for a number of scenarios by the developing

team. One of the recent modifications in FDS is the implementation of a ventilation

module. The first aim of this paper was to validate FDS and ANSYS-CFX within

the Swedish part of the OECD/NEA PRISME project using the PRISME SOURCE D1

test.... (More)
Fire models are used increasingly for fire safety assessment in nuclear power plants.

module. The first aim of this paper was to validate FDS and ANSYS-CFX within

the Swedish part of the OECD/NEA PRISME project using the PRISME SOURCE D1

test. The results are presented in this article and show how powerful the module is for

simulation in enclosures with mechanical ventilation. Beside CFD models, fire safety

engineers need also simple empirical models for determining temperatures, smoke

heights, etc. In the second part of this paper such a model is developed. The model

predicts gas temperatures in a room adjacent to a room involved in a pre-flashover fire.

The correlation is derived with help of computer simulations and validated by means of

a set of fire tests. The results of the correlation model are satisfactory and the correlation

formulae will be an additional tool for fire safety engineers. (Less)
