Wind computation for a zone model

Information

Wind speed computation on a zone

Hypothesis and equations

This model calculates the wind speed on four oriented walls of a zone (North, South, East, West by default).

Bibliography

none

Instructions for use

Model which takes as input the vector V from a weather data reader, with the Universal Time (UTC) as time base to calculate the wind speed on four oriented walls (vertical by default) of a room (North, South, East, West by default).

V contains:

  1. Wind speed (m/s)
  2. Wind direction

Known limits / Use precautions

Warning, the selected convention of wind direction (0° -North, 90° -East, 180° - South, 270 ° -West) must be respected in the weather file!

Moreover it is not the same convention as for the walls (0 ° - South -90 - East 90 - West 180 - North).

Pay aslo attention to the wind direction definition: it is the cardinal point of the wind origin.
