Numerical study of acoustic oscillations and combustion instabilities in solid propellant rocket [PDF]

open access: yes, 1997
A numerical analysis of unsteady motions in solid rocket motors has been conducted. A fully coupled implicit scheme based on a dual time-stepping integration algorithm has been adopted to solve the governing equations and associated boundary conditions.

Exploring the Spillover Effect of Supply Chain Digitalisation on Pollution Emissions Through Social Network Analysis

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The supply chain consists of interconnected businesses and organisations responsible for the flow of goods and services. As firms increasingly adopt digital technologies, the spillover effects of supply chain digitalisation (SCD) on environmental performance remain underexplored.

Bifurcation Dodge: Avoidance of a Thermoacoustic Instability under Transient Operation

open access: yes, 2018
Varying one of the governing parameters of a dynamical system may lead to a critical transition, where the new stable state is undesirable. In some cases, there is only a limited range of the bifurcation parameter that corresponds to that unwanted ...
