    Empirical and phenomenological hydrodynamic reactive flow models, such as Ignition and Growth and Johnson-Tang-Forest, have been effective in predicting shock initiation and detonation characteristics of various energetic substances. These models utilize the compression and pressure properties of the reacting mixture for quantifying their reaction rates. However, it has long been known that shock initiation of detonation is controlled by local reaction sites called ‘hot spots.’ In this study, a hot spot model based on the temperaturedependent Arrhenius reaction rate is developed. The complex reaction process of target explosive is addressed by conducting the Differential Scanning Calorimetry (DSC) while the rate of reaction is determined using the Friedman isoconversional method.
