- Abstract
- Electric vehicles are becoming more common as one of many solutions to the increasingly serious problem of global warming. This comes with new safety challenges as batteries can upon malfunction or abuse enter thermal runaway and as a result catch fire or explode. The gases released from thermal runaway has been determined experimentally in published studies and have been shown to contain fluorinated compounds. Fluorinated compounds have not been thoroughly studied in the larger context of combustion chemistry and there are therefore no standard chemical kinetic mechanisms with fluorinated compounds in them. The goal of this project is to create a chemical kinetic mechanism that can use fluorinated compounds and other, in the combustion... (More)
- Electric vehicles are becoming more common as one of many solutions to the increasingly serious problem of global warming. This comes with new safety challenges as batteries can upon malfunction or abuse enter thermal runaway and as a result catch fire or explode. The gases released from thermal runaway has been determined experimentally in published studies and have been shown to contain fluorinated compounds. Fluorinated compounds have not been thoroughly studied in the larger context of combustion chemistry and there are therefore no standard chemical kinetic mechanisms with fluorinated compounds in them. The goal of this project is to create a chemical kinetic mechanism that can use fluorinated compounds and other, in the combustion research, less common hydrocarbons, such as dimethyl carbonate. The chemical kinetic mechanism was then used in simulations of ignition delay time and flame propagation speed. It was found that mixing fluorinated compounds with other hydrocarbons had a small effect on the ignition time and flame speed. It was also found that a mixture of two compounds will have a flame speed and ignition time between the flame speed and ignition time of mixtures composed of the pure compounds. (Less)
