Numerical Investigation of Heat Transfer Rate Improvement in Heat Exchangers Utilizing Innovative Wavy Vortex Generators

open access: yesModelling and Simulation in Engineering, Volume 2026, Issue 1, 2026.
Quick‐cooling heat exchangers are used for a wide range of industrial applications. This study is aimed at employing the wavy surfaces of the vortex generators to reduce pressure drops and enhance heat transfer performance. The turbulent conditions for mixture (water and air) flow with Rew = 3500–5000.

Influence of Layering and Curie Temperature Uncertainty on the Performance of Multilayer Active Magnetic Regenerators

open access: yesAdvanced Functional Materials, Volume 35, Issue 52, December 23, 2025.
This study examines how manufacturing uncertainties in Curie temperatures (1.5–2°C) affect multilayer active magnetic regenerators (AMR). While increasing the number of magnetocaloric layers boosts cooling power, performance degrades due to temperature variations.

Forced Convection of Carreau Hybrid Nanofluid in a Modified T‐Shaped Cavity Under Inclined MHD and Radiation Effects

open access: yesEngineering Reports, Volume 7, Issue 10, October 2025.
The 2D, steady, laminar forced convection of a Carreau hybrid nanofluid (MgO–Ag/water) in a modified T‐shaped cavity with two outlets and a bottom inlet is investigated numerically in current work. The cold nanofluid enters from the inlet at the bottom with Tc$$ {T}_c $$ and velocity uc$$ {u}_c $$, while the vertical L‐shaped walls (W1$$ {W}_1 $$ and ...
