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 ...

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‐

Achieving 85% Thermal Efficiency: Numerical Performance Analysis of a Solar Air Heater With Curved‐Leg Divided Triangular Tubes

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This article proposes and numerically analyzes a high‐performance solar air heater (SAH) featuring a novel absorber configuration with curved‐leg triangular tubes (CLTTs) under an impingement‐return flow arrangement. The key innovation lies in the tube’s cross‐section, which approximates a triangle with two curved arc‐shaped legs, internally divided by
