Curtis turbineTurbine Tur"bine, n.
A form of steam engine analogous in construction and action
to the water turbine. There are practically only two distinct
kinds, and they are typified in the de Laval and the Parsons
and Curtis turbines. The
de Laval turbine is an impulse turbine, in which steam
impinges upon revolving blades from a flared nozzle. The
flare of the nozzle causes expansion of the steam, and
hence changes its pressure energy into kinetic energy. An
enormous velocity (30,000 revolutions per minute in the 5
H. P. size) is requisite for high efficiency, and the
machine has therefore to be geared down to be of practical
use. Some recent development of this type include turbines
formed of several de Laval elements compounded as in the
ordinary expansion engine. The
Parsons turbine is an impulse-and-reaction turbine, usually
of the axial type. The steam is constrained to pass
successively through alternate rows of fixed and moving
blades, being expanded down to a condenser pressure of
about 1 lb. per square inch absolute. The
Curtis turbine is somewhat simpler than the Parsons, and
consists of elements each of which has at least two rows
of moving blades and one row of stationary. The bucket
velocity is lowered by fractional velocity reduction. Both
the Parsons and Curtis turbines are suitable for driving
dynamos and steamships directly. In efficiency, lightness,
and bulk for a given power, they compare favorably with
reciprocating engines. de Laval turbineTurbine Tur"bine, n.

Turbinal
Turbinal Tur"bi*nal, a. [L. turbo, turben, -inis, a top,
whirl.] (Anat.)
Rolled in a spiral; scroll-like; turbinate; -- applied to the
thin, plicated, bony or cartilaginous plates which support
the olfactory and mucous membranes of the nasal chambers.
Note: There are usually several of these plates in each nasal
chamber. The upper ones, connected directly with the
ethmoid bone, are called ethmoturbinals, and the lower,
connected with the maxill[ae], maxillo-turbinals.
Incurved portions of the wall of the nasal chamber are
sometimes called pseudoturbinals, to distinguish them
from the true turbinals which are free outgrowths into
the chambers.
