Experimental Investigation of an Efficient and Lightweight Designed Counter-Rotating Shrouded Fan Stage [PDF]

International Journal of Turbomachinery, Propulsion and Power
The German Aerospace Center designed, aero-mechanically optimized and experimentally investigated its own counter-rotating shrouded fan stage in the frame of the project CRISPmulti. Their target and the motivation of this work was, on the one hand, the generation of a highly accurate experimental database for the validation of the modern numerical ...

The Lunar Trailblazer Lunar Thermal Mapper Instrument

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract The Lunar Thermal Mapper (LTM) instrument is a UK Space Agency funded infrared radiometer designed and built for the National Aeronautics and Space Administration Lunar Trailblazer mission launched in February 2025. LTM is a pushbroom imaging filter radiometer with 15 channels that cover the wavelength range from 6.25 to 100 μm with a 40–70 m ...

Mass Exchange Flow Process in Side Channel Pumps: Effects of Different Geometrical Parameters

Energy Science &Engineering, Volume 14, Issue 4, Page 2294-2306, April 2026.
Figure 1 shows the Mass Flow Exchange (MFE) in the impeller at z = 7.5 × 10−3 m at 1.0 Q/QBEP, operating point for impeller scheme 1 (IMP 1), and impeller scheme 2 (IMP 2). The flow begins to exit the impeller at the outer radius and enters at the inner and central radii. IMP 1 exhibits more flow in and out compared to IMP 2. ABSTRACT The functionality

A Planetary‐Scale Hydraulic Jump Driving Venus' Cloud Front

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Atmospheric motions generate clouds and influence planetary climate systems. Venus, permanently shrouded by sulfuric acid clouds, provides a striking example. Unlike the photochemically produced upper clouds, the lower cloud layer is thought to form through condensation driven by poorly understood atmospheric dynamics.

Impacts of A‐Site Composition on the Cation Dissolution‐Mediated Surface Restructuring of Layered Nickelate Oxide Electrocatalysts During Alkaline Oxygen Evolution Reaction

ChemElectroChem, Volume 13, Issue 6, 17 March 2026.
This work shows that A‐site composition dictates the restructuring of Ruddlesden–Popper nickelate oxides (A2‐xA’xNiO4; A = La, Eu, Gd; A’ = Sr; x = 0–1.5) under alkaline oxygen evolution reaction conditions and suggests that electrocatalytic stability is governed by an interplay between dissolution‐mediated site exposure and Ni oxidation state ...

Effect of Blade Outlet Angle on Unsteady Hydrodynamic Force of Closed-Type Centrifugal Pump with Single Blade

International Journal of Rotating Machinery, 2014
Geometrically, the single-blade centrifugal impeller, commonly used today as a sewage pump, is not axially symmetric. For this reason, the static pressure around the impeller fluctuates greatly when the impeller is rotating, and not only the radial ...
