THE
MOST COMPREHENSIVE TWO-PHASE THERMOHYDRAULIC ANALYZER AVAILABLE
C&R
TECHNOLOGIES' FLUINT, the flow analyzer in SINDA/FLUINT,
was designed right from the start to handle the peculiarities
of two-phase flows. In fact, its development was initiated
specifically to avoid the shortcomings of single-phase analyzers
that had been retrofitted to adapt to two-phase problems.
Combined
with the heat transfer capabilities of SINDA, the sketchpad
interface of Sinaps®,
the CAD-based interface of FloCAD®
(a module of Thermal
Desktop®),
and the unique capabilities such as parametric analyses, optimization,
calibration, and statistical design, SINDA/FLUINT is truly
in a class by itself.
