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

Engineering 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 ...
