Computational modeling of vapor cloud explosion in off-shore rigs using a flame-speed based combustion model
Computational modeling is a useful tool in determining the consequences from vapor cloud explosions. Here an approach that uses a flame- speed based combustion model is evaluated. Various scenarios of explosions in full-scale off- shore modules are simulated and compared to available test data. The ignition location of the cloud and available venting paths are found to affect the overpressure field in and outside the module. For end ignition cases, the combustion of gas pushed out of the module is found to play a key role. Using the flame-speed based model with appropriate effective flame speeds is found to provide accurate simulations.
