Wind pressure acting on greenhouses: A review

نویسندگان

چکیده

Greenhouses are widely used in agricultural and horticultural production. With the characteristics of lightweight, small stiffness high flexibility, greenhouses sensitive to wind loads. In calculation loads, pressure coefficient (Cp) is essential. The rationality value directly affects safety economy greenhouses. Therefore, Cp values estimation one most important issues design order make full use existing research results, this study, three main methods for estimating were analyzed, namely, full-scale field experiment, tunnel experiment numerical simulation. Five factors influencing then reviewed including greenhouse parameters, group, overhanging eaves, ventilation direction. Based on researches, suggestions future development work also put forward. Owing flexibility deformability greenhouses, fluid-solid coupling method should be analyze effects vibrations pressures. interaction building parameters (such as number spans, ridge height, roof shape slope angle) terrain around taken into consideration comprehensively. destructive vortices occurred further investigated. Keywords: computational fluid dynamics, greenhouse, coefficients, tunnel, influence DOI: 10.25165/j.ijabe.20211402.5261 Citation: Wang C, Nan B, T L, Bai Y K, Li Q. Wind acting greenhouses: A review.

An Experimental Investigation on Dynamic Wind Loads Acting on a Wind Turbine Model in Atomspheric Boundary Layer Winds

An experimental study was conducted to investigate the dynamic wind loads acting on a wind turbine model sited in atmospheric boundary layer winds. The experimental studies are conducted in a large-scale Aerodynamic/Atmospheric Boundary Layer (AABL) Wind Tunnel available at Iowa State University. A three-blade Horizontal Axial Wind Turbine (HAWT) model was placed in atmospheric boundary layer w...

Evolving Greenhouses

To explore the space between the theories of the Diffusion of Innovations and Universal Darwinism, we first examine a case study of the history of the greenhouse horticulture sector of the Netherlands, comparing and contrasting the narrow focus of Diffusion of Innovations and the wider focus of Universal Darwinism. We then build an agent-based model using elements of both in order to test how w...
