Abstract : Bore and chamber surface, as well as subsurface, temperature predictions are made for the U. S. Army M256 120-mm cannon firing M865, M829, and DM13 cartridges. The surface temperature predictions are validated by comparison with other numerical modeling results, while the subsurface temperature predictions are compared directly with experimental measurements made by in-wall thermocouples. The surface temperature predictions fall in line with other numerical estimates, and, in general, the simulated probe temperatures at each axial location are within the circumferential and round-to-round variation in the experimental probe temperatures.
