Extension of analytical indicial aerodynamics to generic trapezoidal wings in subsonic flow [PDF]

Chinese Journal of Aeronautics, 2018
Analytical indicial aerodynamic functions are calculated for several trapezoidal wings in subsonic flow, with a Mach number 0.3≤ Ma≤ 0.7. The formulation herein proposed extends well-known aerodynamic theories, which are limited to thin aerofoils in incompressible flow, to generic trapezoidal wing planforms.

A Detailed Loss Analysis Methodology for Centrifugal Compressors

Volume 2D: Turbomachinery — Multidisciplinary Design Approaches, Optimization, and Uncertainty Quantification; Radial Turbomachinery Aerodynamics; Unsteady Flows in Turbomachinery, 2021
A deep understanding of loss mechanisms inside a turbomachine is crucial for the design and analysis work. By quantifying the various losses generated from different flow mechanisms, a targeted optimization can be carried out on the blading design.

A Study on Improvement of Aerodynamic Characteristics of the Next-Generation SST Wing by Lateral Blowing in Subsonic Flow.

JOURNAL OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES, 2001
An experimental study on the improvement of aerodynamic characteristics of a modified arrow wing by applying lateral blowing in subsonic flow has been conducted. The modified arrow wing, which is one of the baseline configurations of the proto-type of next-generation SST, is selected for the experiments.

Transonic potential flows in a convergent–divergent approximate nozzle [PDF]

, 2008
In this paper we prove existence, uniqueness and regularity of certain perturbed (subsonic–supersonic) transonic potential flows in a two-dimensional Riemannian manifold with “convergent–divergent” metric, which is an approximate model of the de Laval ...

Effect of Tunnel Ventilation on Hydrogen Dispersion From Leaks in Hydrogen Fuel Cell Trucks

Energy Science &Engineering, EarlyView.
This study investigates hydrogen leakage scenarios involving hydrogen fuel cell trucks within tunnels. Using computational fluid dynamics methods, it explores the distribution characteristics of hydrogen concentrations and the efficiency of ventilation under different forced ventilation conditions. ABSTRACT The widespread adoption of hydrogen fuel cell

Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

Strategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

Collisionless Shocks: Contemporary State After Three Quarters of a Century of Research

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract The collisionless shock research started in the late 1950s. Since then, plenty of data have been accumulated due to the large number of missions in the heliosphere, providing in situ measurements of the fields and particles. The quality of these measurements has vastly improved, especially in the last two decades.

Plasma Stability in Turbulent Magnetic Flux Ropes Downstream of a Collisionless Shock

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract How pre‐existing solar wind turbulence, and coherent structures such as magnetic flux ropes within it, influence the transition of plasma across a shock is still poorly understood. Recently, in situ observations from the Earth's magnetosheath have been used to study plasma stability against ion kinetic instabilities. In the turbulent flow, the

Reconnection Preferentially Accelerates Light Ions at Ganymede's Magnetopause

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Juno's flyby of Ganymede revealed ion composition in its vicinity with the Jovian Auroral Distributions Experiment–Ion (JADE‐I) instrument. Throughout this flyby, we derive species‐resolved ion density and velocity moments by decomposing the time‐of‐flight data into contributions from individual ion species using species‐dependent fits. At the
