Wind Tunnel Tests for Wind Pressure Distribution on Gable Roof Buildings

Wind Tunnel Tests for Wind Pressure Distribution on Gable Roof Buildings

Gable roof buildings are widely used in industrial buildings. Based on wind tunnel tests with rigid models, wind pressure distributions on gable roof buildings with different aspect ratios were measured simultaneously. Some characteristics of the measured wind pressure field on the surfaces of the models were analyzed, including mean wind pressure, fluctuating wind pressure, peak negative wind ...

Wind Tunnel Tests on Horn-Shaped Membrane Roof Under the Turbulent Boundary Layer

Wind tunnel tests of a free yawing downwind wind turbine

This research paper presents preliminary results on a behavioural study of a free yawing downwind wind turbine. A series of wind tunnel tests was performed at the TU Delft Open Jet Facility with a three bladed downwind wind turbine and a rotor radius of 0.8 meters. The setup includes an off the shelf three bladed hub, nacelle and generator on which relatively flexible blades are mounted. The to...

An experimental study of flow fields and wind loads on gable-roof building models in microburst-like wind

An experimental study was conducted to quantify the flow characteristics of microburst-like wind and to assess the resultant wind loads acting on low-rise, gable-roof buildings induced by violent microburst-like winds compared with those in conventional atmospheric boundary layer winds. The experimental work was conducted by using an impinging-jet-based microburst simulator in the Department of...

Closed-Loop Control Wind Tunnel Tests on an Adaptive Wind Turbine Blade for Load Reduction

Wind tunnel tests on a non-rotating, dynamically scaled wind turbine blade equipped with variable trailing edge geometry were carried out. The effectiveness of the system for active load reduction purposes, with the interaction between structural dynamics, aerodynamics and control was tested. The actuation of the adaptive trailing edge was based on a piezoelectric bender actuator. The full aero...
