The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history. The field has undergone a continuous evolution, driven by human dependence on water, meteorological conditions and internal ...
Decoupage or découpage ( / ˌdeɪkuːˈpɑːʒ /; [ 1] French: [dekupaʒ]) is the art of decorating an object by gluing colored paper cutouts onto it in combination with special paint effects, gold leaf, and other decorative elements. Commonly, an object like a small box or an item of furniture is covered by cutouts from magazines or from ...
The master is placed on the gelatin and spirits applied to transfer the ink from the master to the gelatin. After transfer of the image to the inked gelatin surface, copies are made by pressing paper against it. When a pad ceased to be useful, the gelatin could be soaked with spirits, the ink sponged away, and the pad left clean for the next ...
Open-cell metal foam CFD (numerical) simulation of fluid flow and heat transfer on an open cell metal foam. Open-celled metal foam, also called metal sponge, [3] can be used in heat exchangers (compact electronics cooling, cryogen tanks, PCM heat exchangers), energy absorption, flow diffusion, CO 2 scrubbers, flame arrestors, and lightweight optics.

Plating is a finishing process in which a metal is deposited on a surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for ...
Exfoliated granite sheets in Texas, possibly caused by pressure release Pressure release or unloading is a form of physical weathering seen when deeply buried rock is exhumed . Intrusive igneous rocks, such as granite , are formed deep beneath the Earth's surface.
Ascending hydrothermal solutions rich in gold, sulfur and metals were channelled upward along major fracture and fault zones. Fluid that made it to the surface would have vented as hot springs and geysers. Localized erosion through the thrust sheet has formed windows into the underlying ore-bearing rocks. Adapted from Edwards and Atkinson (1985).
Capillary surface. In fluid mechanics and mathematics, a capillary surface is a surface that represents the interface between two different fluids. As a consequence of being a surface, a capillary surface has no thickness in slight contrast with most real fluid interfaces. Capillary surfaces are of interest in mathematics because the problems ...
