Unsteady aerodynamic analysis of space shuttle vehicles. Part 1: Summary report [PDF]
An analysis of the unsteady aerodynamics of space shuttle vehicles was performed. The results show that slender wing theory can be modified to give the potential flow static and dynamic characteristics over a large Mach number range from M = 0 to M 1. A

Parameter investigation for urban surface‐energy balance: A large‐eddy simulation study
Quarterly Journal of the Royal Meteorological Society, EarlyView.Large eddy simulation modelling is used to investigate the variation in surface‐energy balance (SEB) across an ensemble of morphometrically identical urban geometries. The geometries have the same plan‐area fraction, vegetated fraction, and frontal‐area index, but are unique in terms of building and green‐space layout.

Long‐Term Morphodynamic Responses to Flood Diversion in the Lower Kano River, Japan
River Research and Applications, EarlyView.ABSTRACT Fluvial morphodynamics—the interaction between water flow, sediment transport, and channel morphology—is a central concern in sustainable river management. However, the long‐term effects of flood diversion remain underexplored. This study investigated the decadal‐scale morphodynamic responses of the lower Kano River in Japan following the ...

Simulation of Nonpremixed Jet Flame Using Flamelet‐Generated Manifold
Safety Science and Technology, EarlyView.A flamelet‐generated manifold (FGM) approach is proposed and validated by nonpremixed methane jet flames. The effects of radiation and buoyancy were critically examined, and nonpremixed and premixed tabulation methods were compared, revealing the importance of radiation, buoyancy, and appropriate flamelet prototype in accurate FGM modeling.

X-Ray Spectrometry, EarlyView.ABSTRACT The diffusion of metal ions in polymer electrolyte membranes is an important parameter for aging and capacity loss in electrochemical cells. Here, the diffusion coefficients of vanadium ions in Nafion membranes are studied. These are important to describe transportation of the ions through the membrane separator in vanadium redox flow ...
