چکیده
The investigation of wind pressure distribution on a façade an atypically shaped 162 m tall building is discussed in this paper. horizontal cross-section was changed with the height structure (the square bottom part and polygon top). surface smooth. A structural system created using combination tube exoskeleton structure. stand-alone, located urban terrain. In case, information standards were not sufficient for its design. Therefore, other available tools had to be used determination required input parameters (mean external coefficients). At first, tunnel tests (WT) performed reduced-scale model (1:300). Then, obtained results compared data from computational fluid dynamics (CFD) simulation. accuracy simulation evaluated by method three metrics. Short descriptions model, boundary layer tunnel, measuring devices, methodology are mentioned. aim research identify influence shape modification values mean coefficients (in comparison original shape, which cuboid). case cuboid, good agreement between determined CFD Eurocode achieved. Larger discrepancies occurred roof. total cuboid atypical positive effect cpe. These smaller (at some levels significantly). Mainly, noticeable leeward side. For directions 0° 180°, changes relatively large. two (45° 67.5°), windward sides similar. large advantage that negative pressures side walls cuboid. This very useful fixing components, where larger than cladding heights.

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 ...
متن کاملCFD for Better Understanding of Wind Tunnel Tests
CFD requires validation for complicated flow problems involving complex physics such as turbulence. Wind tunnels are still the most commonly used validation tools for CFD including physical modelling although some limited use of reliable DNS data base for simple geometries is recently becoming possible. One can observe the trend that a higher and higher demand on the accuracy of the wind tunnel...
متن کاملA method to correct the flow distortion of offshore wind data using CFD simulation and experimental wind tunnel tests
The assessment of wind energy resource for the development of deep offshore wind plants requires the use of every possible source of data and, in many cases, includes data gathered at meteorological stations installed at islands, islets or even oil platforms—all structures that interfere with, and change, the flow characteristics. This work aims to contribute to the evaluation of such changes i...
متن کاملCFD in Wind Energy: The Virtual, Multiscale Wind Tunnel
Over the past two decades, computational fluid dynamics and particularly the finite volume method have been increasingly used to predict the performance of wind turbines within their environment. Increases in available computational power has led to the application of RANS-based models to more and more complex flow problems and permitted the use of LES-based models where previously not possible...
متن کاملWind 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...
