Abstract
This article presents description and results of an investigation using PIV for measuring wind velocity fields in front of and behind bulkheads made from nets of different solidity ratios. The basic aim of the work is to determine the characteristic features of the wind velocity field on the windward and leeward sides of nets of different solidity ratios and to present an example of the usage of a PIV system in tests in an aerodynamic tunnel. The tests were performed in a mini aerodynamic tunnel especially prepared to test the PIV system. In the work, the regulations of measurement by means of a PIV system are presented, the main elements of the system are characterised and the main advantages and difficulties of realising measurements using this type of technique are described.
