TL;DR: In this article, a fundamental consideration is presented for mechanisms of generation of vortex-induced oscillations which are classified into three groups through wind tunnel tests and it is shown that the geometrical shape factor of the section, namely the slenderness ratio, takes an important role here and in addition, the interrelation of the vortices formed at leading and trailing edges and the induced oscillations of sections is clarified.

TL;DR: In this paper, a model is presented for predicting the across-wind response of slender structures of circular cross-section to turbulent shear flow, and a computer program is developed to obtain estimates of response in full-scale situations.

TL;DR: In this article, an analysis of the wind uniform inflow factor through tandem actuator discs indicates that these earlier predictions may be slightly pessimistic, and the authors apply actuator disc theory to a vertical axis wind turbine to determine optimum performance.

TL;DR: In this paper, it is shown that full scale configurations with circular features can be performed satisfactorily provided the test Reynolds number in turbulent flow with turbulence intensity greater than 4%, is in excess of 2×10 5 ; tests at Reynolds numbers below this value are shown to have little relevance to such full scale structures.

TL;DR: In this paper, the effects of free-stream turbulence on a separation bubble formed along a side of a blunt plate with right-angled corners are studied and the surface pressure is estimated in terms of the longitudinal gradient of the time-mean pressure and the length scale of vortices in the reattaching zone.

TL;DR: In this paper, the authors present the case for the wider application of reliability principles in the treatment of wind loading and illustrate the usefulness of its usefulness in treatment of a variety of uncertainties concluding those associated with the estimation of internal pressures, of damping and also the influence of wind direction.

TL;DR: In this article, an analysis of wind loads derived from boundary layer wind tunnel experiments on low buildings sheds light on the question of scaling results are available for building models tested at three geometric scales under two different terrain exposures representing open country and suburban areas.

TL;DR: In this paper, the authors examined the anatomy of wind induced torsional moments on buildings of square and rectangular cross-section using weighted pneumatic averaging to measure the mean and dynamic torque components contributed by particular portions of the building perimeter.

TL;DR: In this paper, the effects of vortex resonance and interference galloping coexist, and model tests with elastic stack models with different mass damping parameters confirm theoretical considerations and show that the effect of interference gallop coexist.

TL;DR: In this paper, a wind-tunnel study has been performed of concentration fluctuations in the near-wake region (1.0 ⩽ x/H ⌽ 5.0 ) of a cubical model building in a simulated, neutrally stratified shear layer.

TL;DR: In this paper, the applicability of the strip and the quasi-steady theories were checked in the light of experimental results of pressures on square prisms in a turbulent boundary layer.

TL;DR: In this paper, Castro et al. used flow visualisatlon to determine the mean characteristics of surface flows, but only in highlighting mean surface flow directions and the location of critical points.

TL;DR: In this article, a model for the prediction of the response of chimneys to vortex shedding is outlined and the major characteristics of solutions employing the model are derived. But the results of the simplified forms are slightly conservative in relation to estimates obtained using the detailed approach.

TL;DR: In this paper, a series of two-dimensional separated-and-reattaching flows are studied, where separation is forced to occur at a sharp edge in each case, and the characteristic dimensionless frequency for the broad band shedding of vorticity from the bubble correlates well between the various geometries provided that it is expressed in terms of the bubble lengh.

TL;DR: In this paper, a wind tunnel investigation of wind pressure distributions over a 1:100 scale model of a 1 1 2 -storey single-family house surrounded by identical building models in various regular arrays is described.

TL;DR: In this paper, the results of a questionnaire survey conducted among the occupants of tall buildings which were subjected to motion during a typhoon were discussed. But the survey focused on the level of tolerance of such motion, about 40% of the occupants on or above the 30th floor stated that they would tolerate such an experience never agian or only once in ten years.

TL;DR: In this article, a flow visualization has indicated the mean flow patterns around 2-D rectangular cylinders exposed to smooth flow and the loci of formation of the wake vortices and the presence of a bubble of separation on the cylinders' side wall.

TL;DR: In this paper, an optimized method for predicting the peak pressure from wind-tunnel model studies was proposed, where the probability distribution of the largest peak pressure achieved during a design storm at a particular location on a building is skewed with a long tail extending toward higher loadings.

TL;DR: A rotor design and analysis code, HELICE as discussed by the authors, exploits analytic simplications possible with near minimum induced loss loading, which has been used to design propellers for human powered airplanes and windmills.
