“…As a result, to investigate wind comfort and safety, computer simulation systems based on CFD technology have been developed [9]. Scholars have extensively compared the accuracy and efficiency of wind tunnel experiments and numerical simulations [10]. The results show that CFD simulation calculations have outstanding advantages in efficiency and cost compared with wind tunnel experiments.…”

Good natural ventilation can improve the comfort of campus dormitories and effectively avoid pollution caused by particle accumulation. Parametric design can effectively address the feedback and connection between building performance analysis and design. This study employs an architect-friendly digital design method based on the Rhino/Grasshopper parametric platform. It takes campus dormitories in the cold region as a case, using parameterized digital tools, such as the Butterfly plugin to simulate wind performance under three influencing factors: building layout, opening position, and building façade (shape and spoiler). Finally, the optimal design that can simultaneously meet the local winter and summer wind environment requirements is selected and validated. In addition, the reasonable design of external balconies and bathrooms in a dormitory can form buffer spaces to achieve effective wind shelter and insulation effects in cold regions. This article describes how to use digital tools to quickly and easily optimize the design of building forms based on wind simulations to promote campus sustainability.

“…Dust particles of 5-10 μm could achieve collection efficiency of more than 90% by increasing the flow rate, whereas the collection efficiency of dust with a particle size of 1-5 μm was below 50%. Computational fluid dynamics (CFD) is one of the key components of the numerical simulation methods [7][8][9]. Lv et al [10] used computational fluid dynamics (CFD) technology to simulate the internal flow field of the cyclone.…”

The cyclone dust collector is an important subsystem of straw crushers used in agriculture. In the present study, a new type of dust collector with involute morphology is proposed to obtain better dust removal efficiency with respect to that of classical tangential and spiral dust collectors. A discrete phase model (DPM) method is used in synergy with a turbulence model, and the SIMPLE algorithm to simulate the flow field inside the dust collector and the related particle dynamics. It is shown that the internal flow field features a primary swirl, a secondary swirl and blockage effects. Moreover, for the involute dust collector, the tangential velocity in the initial stage and the pressure in the high-pressure area are larger than those obtained for the classical types. The dust removal efficiency is 37.11%, 25.3%, and 16.37% for the involute type dust collector, the tangential type and the spiral type, respectively.
