This book was released on 2015 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been much success in atmospheric boundary layer simulation with medium sized closed-circuit wind tunnels with test section dimensions of approximately 1 x 1 m. However, smaller, blower-type wind tunnels are more common in university laboratories due to the lower cost and smaller space requirements. A small size, open flow wind tunnel with a 1 x 1 foot test section was modified to simulate the atmospheric boundary layer with a combination of upstream spires and cubic roughness elements. The primitive spire geometry detailed in the literature was found to yield poor agreement with the power law velocity profile of interest, and a novel iterative algorithm was developed to produce nonlinear spire geometry. The geometry generated by the algorithm was tested in the wind tunnel and found to simulate the desired velocity profile based on a Hellman exponent of 0.20 with a high degree of agreement, having a maximum velocity error of 4%. This confirmed the suitability of small-sized wind tunnels for simulating the atmospheric boundary layer.

Available in PDF, EPUB and Kindle. Book excerpt: "The importance of simulating atmospheric flows in wind tunnels has been well established. Experiments were conducted in the Modified Aerodynamic Wind Tunnel to determine the suitability of this wind tunnel for simulating atmospheric flows and the degree to which various aspects of modeling could be fulfilled. A temperature profile to simulate the inversion aloft was generated inside the test section, and then an appropriate velocity profile was built in by means of screen mesh arrangements. The turbulence characteristics of the flow were measured. The validity of the temperature, velocity and turbulence fields were examined. It was found that while the temperature and velocity profiles were quite valid, the turbulence generated by the screen mesh arrangement was too high. The test section being short, turbulence could not be damped out to the required level. A model smoke stack was introduced into the test section to observe the effect of the modeled inversion on the plume. The smoke velocity could not be effectively controlled, and the plume could only be observed a very short distance downstream. Therefore, the plume path was not very realistic. Other smoke tests in the test section showed maximum turbulence at the surface and no significant change when the temperature profile was introduced"--Abstract, leaf ii.
Download or read book Development of Wind Tunnels for Physical Modelling of the Atmospheric Boundary Layer ABL written by Jack E. Cermak and published by . This book was released on 1994 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents the evolution of physical-modeling techniques to simulate wind and wind effects. Characteristics of atmospheric boundary layers (ABLs) are reviewed and features that require modeling for wind-engineering applications are defined. Similarity criteria are presented for "exact" similarity and necessary approximations are discussed. Special features of wind tunnels needed to achieve the modeling requirements are identified. Comparisons are made of data measured in the field and in a boundary-layer wind tunnel. Wind tunnels with special capabilities for modeling the ABL are described.
