Extending Excitation Time for Detonation Prevention: Mixture Effect in Dimethyl Ether Auto‐Ignition
International Journal of Chemical Kinetics, EarlyView.ABSTRACT Undesired detonation development is an obstacle in the development of modern combustion systems based on auto‐ignition. Excitation time is one of two time scales that affect detonation development. It describes the time interval, during which heat is released.

A Data‐Driven Approach to Integrated Adaptive Morphing and Guidance for Cruise Missiles
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT To address the complex coupling between aerodynamic characteristics and guidance control for morphing flight missiles, this study proposes a data‐driven approach to integrated adaptive morphing and guidance. Firstly, an aerodynamic surrogate model is constructed using a fully connected neural network (FCNN), mapping the configuration ...

Coherence of Coupling Conditions for the Isothermal Euler System
Mathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 11565-11591, August 2025.ABSTRACT We consider an isothermal flow through two pipes. At the junction, the flow is possibly modified by some devices, such as valves, compressors, and so on, or by the geometry of the junction; coupling conditions between the traces of the flow must be given.

Interpreting Energy‐Latitude Dispersions in Mercury's Northern Magnetospheric Cusp With MESSENGER
Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.Abstract We examined energy‐latitude dispersions in Mercury's northern magnetospheric cusp. These systematic trends in plasma energy originate from differences in particle travel time from the dayside magnetopause reconnection site to the low altitude, high latitude cusp.

Heat Transfer, Volume 54, Issue 5, Page 3193-3207, July 2025.ABSTRACT High‐pressure turbine blade tips operate under extreme thermal stress, generating significant aerodynamic losses that must be continually optimized to improve engine efficiency and durability. This study uses computational fluid dynamics (CFD) to investigate the aerodynamic and thermal behavior of advanced turbine blade tip configurations ...

Wind Energy, Volume 28, Issue 7, July 2025.ABSTRACT As the demand for power increases, installing small‐scale wind turbines can be an alternative solution. However, the main challenge for their implementation is the aerodynamic noise. With a view to minimizing noise, this study focuses on the performance investigation of a small‐scale horizontal‐axis wind turbine with NACA 4412 blades inspired ...

Supersonic flows of the Euler–Poisson system with nonzero vorticities in three‐dimensional cylinders
Journal of the London Mathematical Society, Volume 112, Issue 1, July 2025.Abstract We prove the unique existence of three‐dimensional supersonic solutions to the steady Euler–Poisson system in cylindrical nozzles. First, we establish the unique existence of irrotational solutions in a cylindrical nozzle with an arbitrary cross‐section with using weighted Sobolev norms.
