“…Water has a low heat transfer coe cient due to poor thermophysical properties. Therefore to enhance the e ciency of such collectors, a new class of uids known as nano uids has been investigated (see Said et al [2]). A nano uid is a mixture of a base uid and nanoparticles.…”

“…A variety of direct absorption nanoparticles materials had have been analyzed in terms of the enhancement in the photothermal performance, including Ag [27][28][29], Au [30][31][32], CNT (carbon nanotubes) [33][34][35], Cu [36], Al 2 O 3 [37,38], graphite [17], graphene [22], and TiO 2 [39]. In addition to the volumetric heating, direct vapor generation due to localized heating of the As far as the steam generation mechanism is concerned, for nanobubbles to be produced around heated nanoparticles, it has been shown analytically that a minimum radiation flux of 3×10 8 W/m 2 is required to produce nanobubbles on heated nanoparticles [46,49,50], which can may only be reached developed by powerful laser beams.…”

“…where K is the loss coefficient taken according to [27] and In a tube-and-fin type PV/T collector, the role of the absorber plate, which is sandwiched between the PV module and the fluid pipe, cannot be neglected in the heat transfer process. In fact, variations in the thickness of the absorber plate directly influence the overall performance of the PV/T system.…”
