A deep understanding of the internal ballistic process and the factors affecting it is of primary
importance to efficiently design a gun system and ensure its safe management. One of the …

One of the greatest challenges in the design of a gun is to balance muzzle velocity and
recoil, especially for guns on aircrafts and deployable vehicles. To resolve the conflict …

The quest to achieve higher muzzle velocity is one of the key goals for researchers in the
fields of propulsion and ballistic. Based on the conventional chemical propulsion, the two …

Two-phase flow numerical methods are applied in internal ballistics widely, which has made
higher fidelity analysis with minimal cost become an urgent demand. Current methods are …

In a gun system, polydisperse phenomenon may occur due to the local combustion by an
igniter system during the firing process. The Eulerian–Eulerian approach still lacks the …

Purpose–In engineering applications, gas-solid two-phase reaction flow with multi-moving
boundaries is a common phenomenon. The launch process of multiple projectiles is a …

Interior ballistics are completed in tens of milliseconds, as are all gun-firing phenomena.
Thus, some data cannot be measured directly through experimentation. Therefore, such …

In order to combine the advantages of both the Lagrangian and Eulerian algorithm for a
moving boundary, this work presents a two-dimensional axisymmetric computational model …

Рассмотрены методы математического и численного моделирования внутрикамерных
процессов в лабораторных газодинамических баллистических установках (на сжатом …

A model formulated in terms of conserved variables is proposed for its use in the study of
internal ballistic problems of pyrotechnical mixtures and propellants. It is a transient two …
