CFD simulation of cross-ventilation for a generic isolated building: impact of computational parameters
Accurate CFD simulation of coupled outdoor wind flow and indoor air flow is essential for the design and evaluation of natural cross-ventilation strategies for buildings. It is widely recognized that CFD simulations can be very sensitive to the large number of computational parameters that have to be set by the user. Therefore, detailed and generic sensitivity analyses of the impact of these pa...
متن کاملA Comparison of Wind Tunnel and Cfd Methods Applied to Natural Ventilation Design
The design of a naturally ventilated atrium was assessed using both wind tunnel and CFD methods to appraise and modify the response of the system to wind forces. The initial design was expected to be susceptible to flow reversal due to wind forces opposing and ultimately defeating buoyancy forces. Several design options were assessed by both methods. Both the methods were able to provide good i...
متن کاملStudy of the Effects of Building Density and Overall Shape of a City on Pollutant Dispersion by Combination of Wind Tunnel Experiments and Cfd Simulations
Despite the improvement made in controlling local air pollution, urban areas are undergoing increasing environmental pressures and poor air quality is one of the major concerns. Recently, much attention has focused on the relationship between urban form and sustainability. There are indications that the density and the overall shape of cities can have implications on street level ventilation an...
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 کاملCFD Simulations to Examine Natural Ventilation of a Work Area in a Public Building
Natural ventilation has played an important role for many low energy-building designs. It has been also noticed as a essential subject to persistently bring the fresh cool air from the outside into a building. This study carried out the computational fluid dynamics (CFD)-based simulations to examine the natural ventilation development of a work area in a public building. The simulated results c...
