This paper explores the potential of forced convection cooling in a ducted photovoltaic façade unit. Where panel is backed by 5 cm thick insulated duct at depth 50 cm. The heat removal from unit due to investigated with range fan speeds 1 m/s 6 m/s. It found that ΔT between inlet and outlet ranged 2.6–24.6 °C. A speed 4 yielded highest removing 550 W efficiency 51%. Whereas lowest mean PV cell ...

Pileus clouds form where humid, vertically stratified air is mechanically displaced ahead of rising convection. This paper describes convective formation of pileus cloud in the tropopause transition layer (TTL), and explores a possible link to the formation of long-lasting cirrus at cold temperatures. The study examines in detail in-situ measurements from off the coast of Honduras during the Ju...

flow field and heat transfer of a nanofluid, whose non-newtonian behavior has been demonstrated in the laboratory, in a square enclosure have been numerically modeled and investigated. to estimate the viscosity of nanofluid, experimental data of hong and kim, 2012 have been used, and a new model has been proposed. finally, the obtained results have been compared to those of newtonian behavior. ...

A numeriea! investigation for forced convection in a constant-temperaJure parallel pkue channel wilh porous cavity and block alternately emplaced on lhe bottom plaJe is presented in this work. The Brinkman-Forchheimer-extended Darcy mode~ whil:h accounts for the effects of impermeable boundary and inertia, is used to characterize the flow field inside the porous region. Solutions of Ihe coupled...
