Comparison of Digital Computer Simulations of Thermal Environment in Occupied Underground Protective Structures with Observed Conditions
註釋Digital computer programs for the calculation of underground shelter heat transfer are described with respect to their mathematical models, assumption, limitations, parameters, input data and computational techniques. The report also presents comparisons between the calculated shelter thermal environments with the observed for seven different prototype shelters. It has been found that the simple one-dimensional heat conduction model can accurately simulate the thermal environment in large shelters, although complex three dimensional heat conduction models may be needed for a small and shallow underground conduction.
