TITLE : IN-LINE WIND TURBINES

BY : S Zhubrin - CHAM-MEI

DATE: September 1995

PHOENICS VERSION: 1.4 Shareware

DETAILS :

• This case studies the influence of widely-spaced trees on the wake fields generated by two on-line wind turbines located on the complex terrain of Valaam Island, in Ladoga Lake in Northern Russia.

• The standard K-E model is modified to take account of plant airflow interactions, resulting in momentum sinks. The corresponding GROUND codings are made by way of PLANT.

Further details of PLANT:

• PLANT is a PHOENICS add-on which allows users to change the coding within certain GROUND groups and sections using PIL instructions in the Q1 file.

• PLANT can include GROUND coding for non-linear property correlations, interphase transport features, initial fields, non-linear source laws and output control calculations.

• PLANT is intended for use by those with a need to include GROUND routines but who either lack the necessary FORTRAN knowledge or who wish to same time by placing the necessary commands in the Q1 file

• PLANT adds the required coding into GROUND and recompiles the EARTH executable before starting the run.

• PLANT is included in PHOENICS 1.4 Shareware.
