Abstract :
Minimizing the effects of explosions in complicated structures such as oil platforms and refineries is an important concern in the oil and gas industry. Computational modeling of complete structures is unfeasible and thus subgrid modeling must be employed. To be able to do this the loading on individual and small groups of objects must be understood.
In this study a finite volume approach is used to model the loading on plates which have a shock incident upon them. A two-dimensional, conservative, positive, upwind scheme for the Navier–Stokes equations based on a MUSCL type Godunov scheme with Riemann solver is used. A k – ε model which allows for compressibility effects is also implemented to model turbulent effects.
Plates are examined singly and in pairs in four different domains. Each domain is used to investigate a series of models which differ in the distance between plates, with some unexpected results. Comparisons are made between models in each series and also between different series. This allows a description to be made of the effect of plates on other plates in both horizontal and vertical directions
