Synergistic Heat Transfer Enhancement in Triangular Enclosures: Hybrid Nanofluid‐Porous Wavy Fin Systems Under Magnetohydrodynamic and Radiation Effects

Energy Science &Engineering, Volume 13, Issue 12, Page 5924-5948, December 2025.
ABSTRACT This study numerically investigates thermal transport and fluid dynamics in a triangular cavity filled with a MgO–Ag–H2O hybrid nanofluid containing an undulating porous fin under electromagnetic field and thermal radiation influences. The governing equations are solved numerically using the Galerkin finite element methodology with Darcy ...

Study and Analysis of Concentric Shell and Double Tube Heat Exchanger Using Tio2 Nanofluid

Iraqi Journal of Chemical and Petroleum Engineering, 2017
In this paper, nanofluid of TiO2/water of concentrations of 0.002% and 0.004% volume was used. This nanofluid was flowing through heat exchanger of shell and concentric double tubes with counter current flow to the hot oil.
