21Dynamic vapor sorption — (DVS) is a gravimetric technique that measures how quickly and how much of a solvent is absorbed by a sample: such as a dry powder absorbing water. It does this by varying the vapor concentration surrounding the sample and measuring the change in …
22Dynamic Materials Corporation — is a metalworking business. The company operates in two segments, explosive metalworking and aerospace. The explosive metalworking segment utilizes explosives to perform metal cladding and shock synthesis. Its principal product is an explosion… …
23Dynamic equilibrium — For the economic concept, see Dynamic equilibrium (economics) A dynamic equilibrium exists once a reversible reaction ceases to change its ratio of reactants/products, but substances move between the chemicals at an equal rate, meaning there is… …
24Dynamic strain aging — Although sometimes dynamic strain aging is used interchangeably with the Portevin–Le Chatelier effect (or serrated yielding), dynamic strain aging refers specifically to the microscopic mechanism that induces the Portevin–Le Chatelier effect.… …
25Dynamic similarity (Reynolds and Womersley numbers) — Contents 1 Derivation 2 Dynamic similarity use 3 Boundary layer thickness 4 References 5 Exter …
26Dynamic scraped surface heat exchanger — The dynamic scraped surface heat exchanger (DSSHE) was designed to face some problems found in other types of heat exchangers. They increase heat transfer by: removing the fouling layers, increasing turbulence in case of high viscosity flow,… …
27Dynamic scraped surface heat exchangers — Introduction The most important technologies for indirect heat transfer use tubes (shell and tube exchangers) or flat surfaces (plate exchangers). Their goal is to exchange the maximum amount of heat per unit area by generating as much turbulence …
28Dynamic braking — Norfolk Southern Unit #5348 with a Dynamic brake. The cooling grill for the brake grid resistors is at the top center of the locomotive. Dynamic braking is the use of the electric traction motors of a railroad vehicle as generators when slowing… …
29Dynamic combustion chamber — The Dynamic Combustion Chamber is an engine that allows for the combustion of gases in a vacuum or under pressure, eliminating the production of air pollutants.[1] Combined with a clean renewable source of electricity, the Dynamic Combustion… …
30dynamic aquaplaning/hydroplaning — A phenomenon in which aircraft tires run at a high speed over shallow standing water and ride up out of contact with the runway, rendering the brakes practically ineffective. Such a condition occurs usually when the runway is wet and the fluid… …
