fluid-free vacuum
1Vacuum energy — is an underlying background energy that exists in space even when devoid of matter (known as free space). The vacuum energy is deduced from the concept of virtual particles, which is itself derived from the energy time uncertainty principle. Its… …
2Fluid statics — (also called hydrostatics) is the science of fluids at rest, and is a sub field within fluid mechanics. The term usually refers to the mathematical treatment of the subject. It embraces the study of the conditions under which fluids are at rest… …
3Free molecular flow — describes the fluid dynamics of gas where the mean free path of the molecules is larger than the size of the chamber or of the object under test. For tubes/objects of the size of several cm, these means pressures well below 10 3 torr. This is… …

5fluid mechanics — an applied science dealing with the basic principles of gaseous and liquid matter. Cf. fluid dynamics. [1940 45] * * * Study of the effects of forces and energy on liquids and gases. One branch of the field, hydrostatics, deals with fluids at… …
6Vacuum pump — A vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum. The vacuum pump was invented in 1650 by Otto von Guericke. Types Pumps can be broadly categorized according to three… …
7Vacuum distillation — At atmospheric pressure, dimethyl sulfoxide boils at 189°C. Under a vacuum, it distills off into the connected receiver at only 70°C. Vacuum distillation is a method of distillation whereby the pressure above the liquid mixture to be distilled is …
8vacuum technology — Introduction all processes and physical measurements carried out under conditions of below normal atmospheric pressure. A process or physical measurement is generally performed in a vacuum for one of the following reasons: (1) to remove the …
9QCD vacuum — The QCD vacuum is the vacuum state of quantum chromodynamics (QCD). It is an example of a non perturbative vacuum state, characterized by many non vanishing condensates such as the gluon condensate or the quark condensate. These condensates… …
