This paper focuses on the parametric study of steady and unsteady forced and natural convection problems by the certified reduced basis method. These problems are characterized by an input-output relationship in which given an input parameter vector — material properties, boundary conditions and sources, and geometry — we would like to compute certain outputs of engineering interest — heat flux...

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...
