With the rapid development of lithium-ion battery technology, powertrain electrification has been widely applied in vehicles. However, if thermal runaway occurs a pack, venting gas cells will spread and burn rapidly, which poses great threat to safety. In this study, 2D CFD simulation combustion characteristics cell pack is performed, possibility detonation explored. First, numerical model for ...

The ignition problem for the scalar Chapman–Jouguet combustion model without convexity is considered. Under the pointwise and global entropy conditions, we constructively obtain the existence and uniqueness of the solution and show that the unburnt state is stable (unstable) when the binding energy is small (large), which is the desired property for a combustion model. The transitions between d...
