Definitions Page

Page Includes a Link to Acronyms

Links may include a static page that will show a definition for each area, life support, multiphase, etc.

Definitions - A, B, C, etc., list to activate. Some sample definitions below

- C -

Capillary flows

The capability to acquire, transport and reject waste heat from life support systems reliably and efficiently with minimum power, mass and volume is crucial to enabling extended human exploration of space. Verifies and validates wickless heat pipe technologies via experiments and conducts studies of capillary corner flows as a means to provide drainage in low-gravity.

Critical Density

The density at the critical point

- M -

Meniscus

The surface of the liquid-gas boundary, which disappears above the critical temperatur.e

- P -

Phase Change

A change from one state (solid or liquid or gas) to another without a change in chemical composition

- V -

Viscosity

The measure of how strongly a substance resists flow (for example, molasses is more viscous than water.)
