摘要：

A simple computer-based algorithm is presented for estimating the overpressures resulting from a vapour cloud explosion in a vented box with obstacles. The algorithm is based on a very simple description of the physical processes involved. It is compared to a large set of 35 m3 experiments previously conducted by Det norske Veritas. The model contains descriptions of all the most important physical processes, and is capable of systematic refinement. If applied carefully, it could be used as a rapid assessment tool for evaluating the hazard from vented obstructed vapour cloud explosions.
