Thermohydraulic Performance Study of the Effect of Winglet Inserts and a Corrugated Wall in a Rectangular Channel

Case Studies in Thermal Engineering, 2023
This numerical study investigates the enhancement of heat transfer and pressure drop characteristics in rectangular channels with transverse corrugations and longitudinal winglet vortex generators. Numerical simulations cover a range of Reynolds numbers (Re) (5000–20000) using channels with uniform wall heat flux and fixed wavelength.

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.

Analysis of air impact on aircraft engine lubrication system performance

Авіаційно-космічна техніка та технологія
A distinctive feature of an aircraft gas turbine engine (GTE) oil system is that an oil-air mixture, rather than pure oil, circulates through almost all of its components.

Computer analysis of the thermohydraulic measurements on CEA dummy cables performed at CEN-Grenoble [PDF]

Journal of Fusion Energy, 1995
We present here the validation of two computer models for the ITER CICCs based on experimental data produced at CEN-Grenoble. The models, implemented in two finite element computer codes, describe compressible helium flow in a Cable-in-Conduit with central cooling hole.

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 ...

Fin geometry and pitch length optimization for forced convection in tubes a numerical study

Journal of Thermal Engineering
Many applications require smaller, faster, and more powerful electronic devices, leading to excess heat that needs to be removed from the system. Micro-finned tubes are a preferred method to increase the heat-transfer performance of cooling systems ...

Three‐Phase Water‐Rheostat Dump Loads in Hydropower Plants: Failure Analysis of a Flawed Retrofit

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This article analyses a failed retrofit of a three‐phase water‐rheostat dump load in a large hydropower plant, where the original water‐level control was replaced by electrode‐spacing control to improve response speed. Using field tests and 3D simulations, it shows that the new design introduced intrinsic problems which prevented safe achievement of ...
