. b .
IROTFL Parameter specifying heliostat rotation.
= 0, stationary heliostat field;
-= 1, heliostat field rotates synchronously with the
sun in such a way that the sun appears to have no
azimuthal motion. To simulate rotating fields
DELSOL sets the azimuthal angle of the sun to be
always due south of the tower.
Default: IROTFL = 0 (11. B-3)
The following variables require definition only if IDENS 2 9:
DENSIT(K,L) Density (i.e., mirror area to ground area ratio) in
zone (K,L) where K specifies the radial position and L
the azimuthal position.
Constraint: 0.0 5 DENSIT 5 1.0 (1I.B-2,11.C)
Default: DENSIT = 156*1.0 (i.e., user must specify values)
AZMSEP( K
1/2 center to center azimuthal separation of heliostats
in normalized units of heliostat widths (= AAz/Z*WM).
Default: AZMSEP = 13~1.05 (11. B-2, I1 .C)
The following variables require definition only zf IUSERF = 2:
NRADMN L
NRADM&J
(L=l, NAZ )
Boundaries of the user defined field. For the Lth
azimuthal zone, NRADMN(L) is the number of the radial
zone occupied closest to the tower, and NRADMX(L) is
the number of the radial zone occupied farthest from the
tower. If no zones are occupied, NRADMN(L) = NRADMX(L) = 0.
Constraint: NRADMN, NRADMX 5 NRAD
Maximum number of heliostats per row = 648
Default: NRADMN = 12’1
NRADMX 2 12’1 (11 .B-2)
FSLIP Ratio determining slip plane correction; in radial
stagger layouts, excess shadowing and blocking is alleviated
by periodically placing g heliostats on a row where
n+l heliostats would have been based on zone-wise
AR and AAz values. FSLIP is the ratio of (n+l)/n.
Constraint: FSLIP > 1.0
Default: FSLIP = 4./3. (1I.C- 1)
The following input cards are required only if IUSERF = 9 (User defined heliostat field
specified by giving individual heliostat coordinates):
NOTE: These input cards follow NLEFF (see Table A-1). These cards are
not Namelists, they are input with the format specified below.
