LES of N2/H2 Transcritical Injection in a Rocket Combustion Chamber
In modern Launcher Rocket Engines (LRE), the study of the behavior of the injector in combustion chamber has been complicated by the fact that lower...

Measurement and simulation of the VIV response of a submersed drillstring in the transition to a critical flow regime
Vortex-induced vibration (VIV) is a complex phenomenon that involves the hydrodynamics and dynamic behavior of a bluff structure. This article...

Effects of surface roughness and wall confinement on bluff body aerodynamics at large-gap regime
A purely Lagrangian vortex method is employed to investigate turbulent flows past a rough circular cylinder under moving wall effect at large-gap...

Bifurcation structures of a two-dimensional piecewise linear discontinuous map: analysis of a cobweb model with regime-switching expectations
We consider the bifurcations occurring in a two-dimensional piecewise-linear discontinuous map that describes the dynamics of a cobweb model in which...

Normal-form analysis of the cusp-transcritical interaction: applications in population dynamics
Bistability, the presence of alternative stable states, is an important feature of population models as it indicates that long-term predictions are...

An Efficient 1D Hybrid Numerical Model for Bed Morphology Calculations in Alluvial Channels
This paper presents a hybrid numerical model for morphodynamic flow simulation in open channels. For this purpose, a deviatoric version of the Saint...

Generalized model for steady-state bifurcations without parameters in memristor-based oscillators with lines of equilibria
We demonstrate how the pitchfork, transcritical and saddle-node bifurcations of steady states observed in dynamical systems with a finite number of...

Water tunnel testing of downwind yacht sails
Downwind yacht sails, such as spinnakers, are low-aspect-ratio highly cambered wings with a sharp leading edge. They are characterised by substantial...

A predator–prey model with prey refuge: under a stochastic and deterministic environment
This study aims to thoroughly investigate the dynamics of a predator–prey model with a Beddington-De Angelis functional response. We assume that the...

A physics-informed data-driven approach for forecasting bifurcations in dynamical systems
Nonlinear stability analysis plays a key role in the design and evaluation of dynamical systems. Model-based analysis methods require extensive...

Trade-off dynamics and chaotic behavior in nonautonomous prey-predator model with group defense
Ecological “trade-off” is prioritising one trait over another. Predators put their lives at danger to pursue dangerous prey, and their injuries can...
