Computational Investigation of MHD Radiative Flow of Shape‐Dependent Al2O3$$ A{l}_2{O}_3 $$ and Fe3O4$$ F{e}_3{O}_4 $$ Nanofluids in A Semi‐Porous Channel

Engineering Reports, Volume 8, Issue 8, August 2026.
A computational study of unsteady MHD radiative nanofluid flow in a semi‐porous channel reveals that nanoparticle shape, volume fraction, and magnetic effects significantly influence velocity and heat transfer. Results highlight strong coupling between geometric, electromagnetic, and thermophysical parameters in optimizing thermal system performance ...

Unsteady Magnetohydrodynamics Heat‐Generating Oldroyd‐B Nanofluid Flow in a Stretching Power Generator Duct Using the Crank–Nicolson Method

Engineering Reports, Volume 8, Issue 8, August 2026.
This study explores how a heat‐generating Oldroyd‐B nanofluid behaves inside an annular hydromagnetic power‐generator duct with a porous, axially stretching inner cylinder. The coupled flow, heat, mass, and magnetic‐field equations are solved using the Crank–Nicolson method.

Comparative Performance Analysis of Various Flat Plate Solar Collectors Incorporating Spiral and Square Arrangement of Circular Type Riser Tube

Energy Science &Engineering, Volume 14, Issue 8, Page 3828-3847, August 2026.
Three flat‐plate collectors with spiral and square coiled riser tubes were tested and it was found that the spiral type provides the best results with a thermal efficiency of 66.98% for a mass flow rate of 0.4 kg/min. Riser tube geometry is a key factor in optimizing flat‐plate collector output.
