TL;DR: In this article, the experimental studies carried out on a 3'×'5 bundle of 25.4'mm Al horizontal tubes with thermal spray coating of aluminum were studied, and the influence on temperature profile, heat transfer coefficient, mass evaporation, etc.
Abstract: Multi-effect distillation is an important principle in desalination technology, in which the thin film evaporation of sea water takes place at the outer surface of bundle of tubes, normally arranged in horizontal. Heat of condensation inside the tube is transferred to the falling water film by conduction, thereafter convective evaporation of film takes place. Heat transfer on the outside is unpredictable due to the uncertainty in nature of film, film thickness, film dryout, etc. and film coefficient is considerably less compared to inside. Thermal spray coating on metallic surface with molten metal particles create porous surface which enhances heat transfer due to higher turbulence and nucleation sites, if sufficient temperature difference available. This paper discusses the experimental studies carried out on a 3 × 5 bundle of 25.4 mm ∅ Al horizontal tubes with thermal spray coating of aluminum. Influences on temperature profile, heat transfer coefficient, mass evaporation, etc. are studied. A c...

TL;DR: In this paper, a method of fabricating copper foam has been described and the characterization of copper foam was carried out by scanning electron microscope (SEM) and X-Ray Diffractogram (XRD) analysis.
Abstract: This work is carried out to study the copper metal foam as porous wick structure in a flat heat pipe. The method of fabricating copper foam has been described. The characterization of copper foam has been carried out by scanning electron microscope (SEM) and X-Ray Diffractogram (XRD) analysis. Effect of liquid velocity on pressure drop and maximum capillary heat transport of fabricated copper foam has been presented.

TL;DR: The title molecular salt, C8H12N+·C7H5O3 − arose from the proton-transfer reaction between 2,5-xylidine and salicylic acid, and features weak C—H⋯O bonds and aromatic π–π stacking [centroid-to-centroid distance = 3.7416 (10) Å] interactions, which lead to a three-dimensional network.
Abstract: The title molecular salt, C8H12N+·C7H5O3− arose from the proton-transfer reaction between 2,5-xylidine and salicylic acid. In the anion, the dihedral angle between the planes of the aromatic ring and the –CO2− group is 11.08 (8)°; this near planarity is consolidated by an intramolecular O—H⋯O hydrogen bond. In the crystal, the components are connected by N—H⋯O hydrogen bonds, with all three O atoms in the anion acting as acceptors; the result is a [100] chain. The structure also features weak C—H⋯O bonds and aromatic π–π stacking [centroid-to-centroid distance = 3.7416 (10) A] interactions, which lead to a three-dimensional network.
