• Abstract:
  The validated solution to a two-term heat transfer model of a bomb calorimeter allows direct calculation of the heat released in an arbitrary process from the recorded temperature history without the need to correct for non-adiabatic behavior. The heat transfer coefficients and thermal capacities of the bomb calorimeter used in the heat calculation are determined parametrically from the temperature response to a known heat impulse (i.e., benzoic acid combustion). This methodology allows accurate measurement of heat released intermittently or during an extended period of time in a bomb calorimeter, as occurs during electrical resistance heating and subsequent thermal runaway of lithium ion batteries.
