Calculations of SRI International MX Trench Expansion and Venting Experiments.

Abstract

Three calculations were performed corresponding to Tests 11, 17 and 18 of the SRI International 'Laboratory Investigations of the Expansion and Venting of the MX Trench' program. Based on analyses of the SRI International experimental data and the results of several preliminary calculations (not reported here), a new model for trench venting was developed. The new venting model is based on simple jet penetration theory. The theoretical results show good overall agreement with the experimental data. In particular, the in-trench pressure histories and trench expansion results for the Test 18 calculation, incorporating the new venting model, agree well with the experimental data. Although further calculations and analyses are required to investigate the applicability and limitations of the venting model, the good agreement between the theoretical and experimental results for Test 18 is encouraging.
