31Derivation of the Navier–Stokes equations — The intent of this article is to highlight the important points of the derivation of the Navier–Stokes equations as well as the application and formulation for different families of fluids. Contents 1 Basic assumptions 2 The material derivative 3 …
32Rheology — is the study of the flow of matter: mainly liquids but also soft solids or solids under conditions in which they flow rather than deform elasticallyW. R. Schowalter (1978) Mechanics of Non Newtonian Fluids Pergamon ISBN 0 08021778 8] . It applies …
33Shear modulus — SI symbol: G SI unit: gigapascal Derivations from other quantities: G = τ / γ …
34Ice sheet dynamics — describe the motion within large bodies of ice, such those currently on Greenland and Antarctica. Ice motion is dominated by the movement of glaciers, whose gravity driven activity is controlled by two main variable factors: the temperature and… …
35Marsh funnel — The Marsh funnel viscometer is a simple device for measuring viscosity from the time it takes a known volume of liquid to flow from the base of a cone through a short tube. It is particularly used by mud engineers to check the quality of drilling …
36Slurry ice — is a phase changing refrigerant comprised of millions of ice “micro crystals” (typically 0.1 to 1 mm in diameter) formed and suspended within a solution of water and a freezing point depressant. Some compounds used in the field are salt (sodium… …
37Perm (hairstyle) — A permanent wave, commonly called a perm, is the chemical and/or thermal treatment of hair to produce waves or curls. The use of the word permanent is justified insofar as when the wave is permed, it remains so; however, as the hair grows, the… …
38Mendeleev readings — a solemn act, the annual reports of leading Soviet/Russian scholars on topics affecting all areas of chemistry and its related sciences: physics, biology and biochemistry. Date of readings is due to two dates: birthday of Dmitri Mendeleev (8… …
39Hill yield criteria — Rodney Hill has developed several yield criteria for anisotropic plastic deformations. The earliest version was a straightforward extension of the von Mises yield criterion and had a quadratic form. This model was later generalized by allowing… …
40Hydrogen damage — is the generic name given to a large number of metal degradation processes due to interaction with hydrogen.Hydrogen is present practically everywhere, in the atmosphere, several kilometres above the earth and inside the earth. Engineering… …
