Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2013.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (p. 203-205).<br>Underwater implosion, the rapid collapse of a structure caused by external pressure, generates a pressure pulse in the surrounding water that is potentially damaging to adjacent structures or personnel. Understanding the mechanics of implosion, specifically the energy transmitted in the pressure pulse, is critical to the safe and efficient design of underwater structures.

Quel que soit le système de gestion adopté, les aléas de production, les retards, les commandes urgentes, les variations des carnets de commande entraînent de nombreux dysfonctionnements. Il en découle des différences entre le niveau réel des stocks et le niveau nécessaire au système de gestion. Peut-on pallier ce problème ? Pour répondre à cette question, nous avons développé un concept basé sur une approche de replanification amont appelé implosion.

Abstract (sommario):

The present study deals with the development of a single-stage implosion-driven hypervelocity launcher. A thin-walled tube filled with helium surrounded by explosives acts as a driver for the launcher. Implosion of the tube drives a strong shock that reflects back and forth between the projectile and the implosion pinch, generating very high temperatures and pressures. Simple analytic models were used to approximate the performance of the pump tube and its use as a driver for a launcher. Experiments to evaluate the implosion dynamics and performance of the pump tube were carried out, and implo

Abstract (sommario):

When massive stars form, they emit strong, hydrogen ionising radiation fields into their molecular cloud environment, forming HII regions. This is believed to be capable of inducing effects which can trigger further star formation through a process known as Radiative Driven Implosion. Hydrodynamic shock fronts are generated at the interface between ionised and un-ionised material. These shocks propagate into the clouds, and their motion and increase in density can result in the conditions required for star formation. Using the method of Smoothed Particle Hydrodynamics, the effect of varied ini

Abstract (sommario):

The present study deals with the evaluation of several explosive phase velocity techniques to produce very high apparent detonation velocities on linear or cylindrical targets. In particular, the pairing of two explosive components with different detonation velocities to drag a structured detonation wave was shown to be accurate in generating desired phase velocities. The technique of subdividing a detonation wave into multiple, discrete detonation channels and injecting them into the desired geometry was also evaluated and shown to be similarly accurate.

Abstract (sommario):

The development of efficient algorithms to understand implosion dynamics presents a number of challenges. The foremost challenge is to efficiently represent the coupled compressible fluid dynamics of internal air and surrounding water. Secondly, the method must allow one to accurately detect or follow the interface between the phases. Finally, it must be capable of resolving any shock waves which may be created in air or water during the final stage of the collapse. We present a fully Lagrangian compressible numerical framework for the simulation of underwater implosion. Both air and water are

Abstract (sommario):

The ability to soft-launch projectiles to velocities exceeding 10 km/s is of interest for a number of scientific fields, including orbital debris impact testing. Current soft-launch technologies have reached a performance plateau below this operating range. In the implosion-driven launcher (IDL) concept, explosives are used to linearly implode a pressurized steel tube, thereby dynamically compressing a light driver gas to significantly higher pressures and temperatures than typical light-gas launchers. As a result, the IDL has the potential to significantly outperform current state of the art

Abstract (sommario):

In this thesis we examine the bifurcation in behaviour (for the dynamics) which occurs when we perturb the holomorphic germ fo(z) =z + zv+1 + O(zv+2) defined in a neigh- bourhood of 0, so that the multiple fixed point at 0 splits into v+1 fixed points (counted with multiplicity). The phenomenon observed is called the parabolic implosion, since the perturbation will typically cause the filled Julia set (if it is defined) to "implode. " The main tool used for studying this bifurcation is the Fatou coordinates and the associated Ecalle cylinders. We show the existence of these for a family of wel

This configuration preconditions the load wires (heating and expanding wires into columns of gas) before allowing the full current to rapidly switch into the load. The preconditioning effect of cylindrical Al wire array loads of different wire numbers and wire thicknesses were investigated from density analysis of laser interferometry. It was found that thicker wires expand to larger diameters than thinner wires in

Abstract (sommario):

Compressible turbulent mixing evolving from Richtmyer–Meshkov and Rayleigh–Taylor instabilities and Bell–Plesset effects has been investigated using carefully designed high-resolution spherical algorithms and implicit large eddy (ILES) simulations of fundamental spherical implosion problems. Multimode narrowband and broadband initial perturbations consisting of spherical harmonics and multimode cosine perturbations are investigated considering a high Atwood number (At = 0.9) setup and a moderate convergence ratio Cr = 3.6. Several integral quantities, mixedness parameters and turbulence statis

Abstract (sommario):

To date our understanding of strongly coupled, degenerate plasmas is incomplete. In particular considerable disagreement exists between theories of hydrogenic matter (HM) at pressures greater than 100 gigapascals (GPa) and temperatures below 3 electronvolts (eV). The predicted transition of fluid molecular hydrogen to a metallic atomic liquid has large implications for models of the interior structure and evolution of gas giants. Experimental confirmation of this transition is still pending. Furthermore, the properties of deuterium-tritium in this regime are of great interest to inertial confi

Such conditions arise during the shock convergence phase of inertial confinement fusion (ICF) implosions, when they may modify the compression and ignition of the fuel from the evolution predicted by main-line hydrodynamic simulations. Kinetic plasma dynamics relevant to ICF

Using CR-39 nuclear track detectors, PCIS applies the technique of penumbral imaging to measure the radial profile of D-D and D-3He protons produced by implosions of D2-3He-filled capsules. For capsules with 20 [mu]m-CH shells, images of D-3He protons resulted in Gaussian profiles with an average l/e radius of [approx.]35
