Abstract:
The status of release MAR-1995 of the computer program PHATAS-III and ofthe postprocessor for its binary output files is described. The postprocessor
provided with PHATAS-III differs from the postprocessor provided with
PHATAS-II release NOV-1994 because the contents of the binary data files are
different. By reading the release label from the heading of the binary data
files the postprocessor can retrieve properties from binary data files of
PHATAS-III, and of PHATAS-II release NOV-1994 or APR-1994. This document
includes the specifications of the code, the relevant modifications with
respect to PHATAS-II release NOV-1994 and a list of the appropriate
documentation. The output files of this PHATAS-III release are identified by
a label in the heading, which is Release: MAR-1995. Release MAR-1995 is
validated by comparison of calculated results with those from release
NOV-1994 following the cases in the Test Procedure and one additional
configuration dealing with a free yawing wind turbine subjected to stochastic
wind generated with SWIFT. Some test cases are modified such that they
include the 3D correction on the airfoil properties, the structural damping
for blade bending deformation and the dynamic wake model for the free yaw
case. Also some additional tests are performed dedicated to quantitative
validation of the structural damping and on the proper functioning and the
consistency of the 'dynamic wake' model. Finally this document includes the
hardware requirements and an installation guide for the SUN version and for
the DOS version. 29 figs., 15 tabs., 11 refs.
