TL;DR: In this paper, the authors extended the design concept for generating multi-scale structures in forced convection for a finite-size flow system to a three-dimensional heat-generating plate with the objectives of maximising heat transfer rate density, or the heat transfer per unit volume.

TL;DR: In this article, the heat transfer and pressure drop characteristics of forced convection were investigated in smooth horizontal circular tubes with both upward and downward flows through a smooth circular test section, and a revised laminar Nusselt number correlation for smooth circular tubes was developed.

TL;DR: In this article, the effect of gravity forces during condensation of R134a in an 8.38 mm inner diameter smooth tube in inclined orientations was investigated. And the flow pattern, heat transfer coefficient and pressure drop were presented as a function of the inclination angle for different mass fluxes and different vapour qualities.

TL;DR: In this article, the authors investigated the effect of inclination angle on condensation inside a smooth tube at different inclination angles and found that the effect was negligible at high mass fluxes and vapour qualities.

TL;DR: In this paper, the effect of gravity forces during condensation of R134a in an 8.38 mm inner diameter smooth tube in inclined orientations was investigated. And the flow pattern, heat transfer coefficient and pressure drop were presented as a function of the inclination angle for different mass fluxes (G = 200 − 400 kg/m2s) and different vapour qualities (x = 0.1 − 0.9).
