TL;DR: In this paper, the authors numerically analyzed the heat transfer and entropy generation characteristics in a two-dimensional porous right-angled triangular enclosure with undulations on the left wall and found that for lower values of Rayleigh number, heat transfer is dominated by conduction mechanism.

TL;DR: In this paper, the effect of Rayleigh number, Darcy number, and undulations on the heat transfer, fluid flow, and entropy generation in a two-dimensional porous right-angled triangular enclosure with one wavy wall is studied numerically.
Abstract: In the present study, natural convection in a two-dimensional porous right-angled triangular enclosure with one wavy wall is studied numerically. Three cases with one, two, and three undulations on the left wall are studied in this analysis. The stream function-vorticity equations are solved using finite-difference technique and a structured nonorthogonal body-fitted mesh is used for computations. The effect of Rayleigh number (Ra = 103–106), Darcy number (Da = 10−4–10−2) and undulations on the heat transfer, fluid flow, and entropy generation is investigated. It is found that average Nusselt number increases with Darcy number and number of undulations present on the left wall at fixed Darcy number.

TL;DR: In this paper, the effects of the modified capillary number and surface wettability, including the obstruction size and architecture, are elucidated to explore the dynamic behavior of droplet motion past an obstruction, and a trade-off between the time required for the bulk droplet fluid to pass by and/or through the obstruction and the fraction of the droplet volume adhering to the surface is revealed.
Abstract: This study presents droplet dynamics due to capillarity-wettability interaction through a partially obstructed channel confinement based on a mesoscopic, two-phase lattice Boltzmann model. To explore the dynamic behavior of droplet motion past an obstruction, the effects of the modified capillary number and surface wettability, including the obstruction size and architecture, are elucidated. In this work, a single spherical obstruction and different spherical agglomerate structures have been considered. The mesoscale simulations exhibit interesting two-phase flow physics and pattern formations due to droplet pinching, break up, and surface adherence owing to the underlying wettability-capillarity characteristics. This study further reveals a trade-off, between the time required for the bulk droplet fluid to pass by and/or through the obstruction and the fraction of the droplet fluid volume adhering to the surface, depending on the combination of the capillary number and surface wettability.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …
