| Summary: | Nanofluid-based direct solar receivers, where nanoparticles in a liquid medium can scatter and absorb solar radiation, have recently received interest to efficiently distribute and store the thermal energy. The objective of the present work is to investigate theoretically the unsteady homogeneous Hiemenz flow of an incompressible viscous nanofluid past a porous wedge due to solar energy (incident radiation). The conclusion is drawn that the temperature is significantly influenced by magnetic strength, nanoparticle volume fraction, convective radiation and porosity of the wedge sheet. |
