    Abstract
    In this report a study of the pressure generated by burning of gunpowder in gun barrels has been carried out. Calculations using the model were compared with experimental results and with results from the standard NATO internal ballistic code (IBHVG98). The numerical calculations gave good agreement with experiments of the gas pressure in gun barrels and of the velocity of projectiles. This indicates that the implemented model is viable and can be used for instance in parametric studies. By using the model the scattering of some experimental results are analyzed. Also some critical physical assumptions in the IBHVG98 code are pinpointed.
