15Turbine — A turbine is a rotary engine that extracts energy from a fluid flow. Claude Burdin (1788 1873) coined the term from the Latin turbo , or vortex, during an 1828 engineering competition. Benoit Fourneyron (1802 1867), a student of Claude Burdin,… …
16Heat pump — A heat pump is a machine or device that moves heat from one location (the source ) to another location (the sink or heat sink ), using work. Most heat pump technology moves heat from a low temperature heat source to a higher temperature heat sink …
17Stall (flight) — For other uses, see stall. In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is… …
