Dynamic Simulation of Micro-flyer Shocked Detonation

Detonation Structure Simulation with AMROC

Numerical simulations can be the key to the thorough understanding of the multi-dimensional nature of transient detonation waves. But the accurate approximation of realistic detonations is extremely demanding, because a wide range of different scales needs to be resolved. In this paper, we summarize our successful efforts in simulating multidimensional detonations with detailed and highly stiff...

DFTB-MD Simulation of Shocked Water Cluster

Relatively efficient and precise quantum molecular dynamics simulations were performed to gain fundamental insights into the mechanisms for the primary detonation process of water under shock wave loading using self-consistent charge density-functional tight binding (SCC-DFTB) calculations combined with the multiscale shock technique (MSST) as well as DFTB+ program conjunct with MSST. We observ...

Efficient Simulation of Multi-dimensional Detonation Phenomena

The paper presents a solution strategy for Euler equations for multiple thermally perfect gaseous species with detailed chemical reaction. Via operator-splitting a high-resolution finite-volume scheme and a stiff ODE solver are coupled. A parallel blockstructured adaptive mesh refinement algorithm is utilized to achieve the required local resolution. A highly resolved computation of regular det...

Numerical Simulation of Pulse Detonation Engine Phenomena

This computational study examines transient, reactive compressible flow phenomena associated with the pulse detonation wave engine. The PDWE is an intermittent combustion engine that relies on unsteady detonation wave propagation for combustion and compression elements of the propulsive cycle. The present computations focus on high order numerical simulations of the generic PDWE configuration w...
