ABSTRACT
The
goal of this study is to model the effects of wind on Cylindrical
Trough Collectors (CTCs). Two major areas are discussed in this paper:
1) heat losses due to wind flow over receiver pipe and 2) average forces
applied on the collector’s body. To accomplish these goals a 2D
modeling of CTC was carried out using commercial codes with various wind
velocities and collector orientations. Ambient temperature was assumed
to be constant at 300 K and for specific geometries different meshing
methods and boundary conditions were used in various runs. Validation
was done by comparing the simulation results for a horizontal collector
with empirical data. It was observed that maximum force of 509.1 Newton
per Meter occurs at +60 degrees. Nusselt number is almost the constant
for positive angles while at negative angles it varies considerably with
the collector’s orientation.
