Abstract

For the study of factors influencing the velocity fields produced by the burning of clouds of flammable substances several computer codes have been developed to aid these studies. This report concerns an extension of these studies, which involves firstly, the use of the existing codes for systematic parameter surveys and secondly, the removal of some of the limitations on the code capabilities towards a more realistic representation of real explosions. This work is all aimed at the study of wave and velocity fields and the influence of rigid boundaries, e.g. buildings (nuclear power plants). Calculations have been undertaken for a number of different fuels and at different concentrations and burning velocities. The results of some of these calculations have then been used in two-dimensional wave structure interaction calculations. Finally, the development of a two-dimensional code capable of modelling flame and pressure wave interactions with structures is presented. The flux corrected transport method (the state-of-the-art method for dealing with flow with shocks) is used to solve a system of equations consisting of the usual conservation equations and a simple turbulence model.
