Numerical Simulation of a Parabolic Trough Solar Collector Equipped with a Vortex Generator under Magnetic Field Using CuDWCNT/Therminol VP-1 Hybrid Nanofluid

چکیده مقاله

This study numerically investigated the thermal performance of a parabolic trough solar collector (PTSC) equipped with a vortex generator (VG), which was under an external magnetic field, using a two-phase hybrid nanofluid (Cu-DWCNT/Therminol VP-1). Key parameters such as Reynolds number, nanoparticle concentration, and magnetic field intensity were analyzed.The paper presents a numerical simulation of heat transfer and fluid flow in a PTSC, using a hybrid nanofluid (Cu-DWCNT/Therminol VP-1) enhanced by vortex generators and exposed to a transverse magnetic field. Results showed that with 4% nanoparticle concentration, with Reynolds number of 33,000, and with optimized VG geometry (Case F), the exergetic efficiency increased by 65.83%. Moreover, the highest thermal enhancement under magnetic influence was observed at Hartmann number Ha = 125 and Re = 21,000
