Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

A Comparative Study of Context‐Aware Modeling Approaches for Specific Heat Load Profiles for Residential Consumers in District Heating Simulations

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Accurate, time‐resolved heat load profiles are essential for realistic district heating simulations, enabling optimized network operation and long‐term transformation planning. In this work, we systematically evaluate modeling approaches for generating such profiles, comparing data‐driven methods (e.g., regression and machine learning) with ...

Stereoscopic Serpentine Channel‐Based Cold Plate Design for Enhanced Liquid Cooling of EV Batteries

Battery Energy, Volume 5, Issue 3, May 2026.
The Graphical Abstract shows a 16‐cell battery pack used in the numerical study, along with temperature contours on the surface of coolant flow channels and a transient average surface temperature plot. A serpentine base plate and a stereoscopic serpentine cold plate are investigated, and the results are compared.

Technological Properties of Biocomposites Produced With Agro‐Industrial Castor Waste Applicable in the Thermal Insulation of Buildings

Polymer Composites, Volume 47, Issue 8, Page 7360-7378, 20 April 2026.
Biocomposites produced with agro‐industrial waste from castor hulls and pinewood bonded with urea‐formaldehyde adhesive, intended for application as thermal insulation in buildings. ABSTRACT The production of composite particleboards with agricultural waste has been the focus of many studies that aim to address environmental problems due to waste ...

Characterization of Fuel Rods Supported by Dimple‐Less Spacer Grids and Subjected to Nonlinear Vibrations

International Journal of Mechanical System Dynamics, Volume 6, Issue 1, Page 3-21, March 2026.
ABSTRACT An experimental campaign was undertaken to demonstrate the applicability of the Bouc–Wen hysteretic model to describe the hysteretic system of the recent Framatome dimple‐less spacer grid design for Pressurized Water Reactors. The experimental setup subjected a reduced‐length fuel rod, supported at both ends by dimple‐less grids, to forced ...

Impact of Leading and Trailing‐Edge Perforations on the Thermohydraulic Performance of Rectangular‐Winglet Vortex Generators

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
In this study, the thermohydraulic performance of rectangular‐winglet vortex generators (VGs) with different hole configurations (a central hole, dual‐edge holes, a leading‐edge hole, and a trailing‐edge hole) was numerically investigated. In addition, airflows through solar air heater ducts enhanced with these VGs were simulated using the realizable k‐

A Novel Tubular Solar Air Heater With Internal Plates: A CFD Study on Segregated Impingement Flow

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This paper presents a numerical analysis of a novel and efficient solar air heater (SAH) designed with an integrated impingement‐return configuration to enhance thermal performance. The system consists of nine blackened copper tubes where incoming air first passes through the lower half of each tube. At the far end, the flow reverses direction in a 180°

Analysis of Temperature and Displacement Fields in the Freeze Construction of Overlapping Cross‐Passages Within Water‐Rich Sand Layers

Geofluids, Volume 2026, Issue 1, 2026.
In the construction of an F‐type cross‐passage in an overlapping‐type shield tunnel using the artificial ground freezing method, the development of the distal frozen wall is difficult to control, and ground deformation is influenced by the superimposed disturbance of successive construction steps. Existing studies are insufficient to fully characterize

Coupling OpenFOAM with 1D thermohydraulics via preCICE [PDF]

, 2021
Nuclear reactor safety relies on the simulation of the complex reactor cooling systems under a broad range of operation and accident conditions. Established codes, such as ATHLET, provide extensively validated 1D models of the involved devices and connecting pipelines.
