Study of the wind-pressure distribution of flat-roof parabolic condensers based on wind-tunnel tests

نویسندگان

چکیده

Abstract The structure of parabolic condensers makes them susceptible to wind load because their thin and large windward mirrors. In this paper, the pressure on a model condenser mirror (1:35) multistorey flat roofs is analysed via measurement in tunnel. mean wind-pressure distribution law flat-roof mirrors (including change with working conditions maximum characteristics) fluctuating extreme are obtained. Furthermore, by comparison ground-based law, similarities differences between two Research results show that same as those ground, but coefficient (absolute value) generally ~30% smaller. effect located at edge more directions 30° 135°–150°. study can provide theoretical reference for wind-resistant design condenser-related research.

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 Investigation of Pressure Distribution and Transition Position of a Swept 3D Wing

Extensive wind tunnel tests are conducted to evaluate surface pressure distribution of a semi span swept wing. The wing section has a laminar flow airfoil similar to NACA 6-series airfoils. The investigations are conducted at various speeds and angles of attack. Surface pressure distribution over the wing upper surface is measured for both chordwise and spanwise sections. Statistical analyses a...

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...
