Opensource software simulations towards understanding, monitoring and controlling COVID-19 transmission by managing air, people distancing and adapting urban environments: ventESI

对于提供者和使用者来说，是否有信心在公共事业、休闲设施、社交和工作互动方面恢复到更正常的水平，在很大程度上取决于知情的选择，以最大限度地减少对冠状病毒的接触并减少其传播。新冠肺炎通过气雾剂传播，即感染者呼吸中的空气颗粒物，导致公共环境中的第三方直接或间接受到污染。它可以发生在任何地方：餐馆、剧院、礼拜场所、体育场、候车室、健身房、公共交通工具，在这些地方，不受控制的空气流动在从载体运输颗粒物方面造成了无限的排列。因此，通过控制通风和可管理的干预措施模拟固定城市环境中的空气流动提供了非常实用的缓解传播的手段。我们的目标是预先验证所有相关的物理建模基础，建立使用这种数字技术的默认最佳实践，创建评估城市布局有效性的措施，最重要的是，为非专家提供对空气运动进行建模和评估几种预防干预措施的机会。数字技术是基于计算流体动力学(CFD)的。该项目的成果使英国普通公用事业提供商能够通过英国的高性能计算(HPC)设施和其他高性能计算或云计算提供商访问空气流动的模拟“试运行”场景。

For both providers and users, confidence in returning to more normal levels of behaviour around public utilities, leisure facilities, social and work-based interaction relies largely on informed choices to minimise exposure to Coronavirus and mitigate its transmission. COVID-19 spreads via aerosols, airborne particles from an infected person's breathing leading to direct or indirect contamination of third parties in communal settings. It can happen anywhere; restaurants, theatres, places of worship, stadia, waiting rooms, gyms, public transport, where uncontrolled air movement creates an infinite number of permutations in transporting particulates from a carrier. Hence, the simulation of air movement in fixed urban settings with controlled ventilation and manageable interventions provides highly practical means of mitigating transmission. We aim to pre-validate all the relevant physics modelling bases, establish defaulting best practices in the use of this digital technology, create measures to assess the effectiveness of urban layouts and, most importantly, provide access for non-experts to model air movement and assess several prevention interventions. The digital technology is based on Computational Fluid Dynamics (CFD). The outcomes of this projects give UK general public utility providers access to simulations of air-movement "try-out" scenarios via high performance computing (HPC) facilities in the UK and other HPC or Cloud-computing providers.
