![]() The dimensionless bubble period and maximum radius agreed with each other when π 4 is constant. The results show that changes of gravity acceleration or hydrodynamic pressure almost has no influence on shock wave peak pressure and time constant as long as π 3 is constant. The tests are classified into different groups to validate scaling laws as well as calibrate coefficients in empirical formulae for both shock wave and bubble oscillation. To validate scaling laws, 17 UNDEX tests are designed by varying accelerations or explosive weights and positions in centrifuge. ![]() Two dimensionless numbers, i.e., π 3 and π 4, are used to characterize shock wave and bubble oscillation, respectively. Scaling laws for UNDEX in centrifuge have been proposed based on dimensional analysis. Describe what you would see as you approached the ground.Centrifuge is a promising tool for underwater explosion (UNDEX) research as both Mach and Froude similitudes could be satisfied with hyper-gravity in models, which would result in similarities in both shock wave and bubble oscillation. Suppose you were riding a stone that was thrown off the roof ofa building. resistance? (Consider the motion of a feather and a steel ball.) 5.
