Taking measures to ensure the health and safety of occupants within buildings due to airborne contaminants will likely be more important than ever as the world comes out of the Covid-19 pandemic. Despite significant advances in our understanding of room ventilation over the past 20 years there is a fundamentally limited understanding of how the influence of the motions created by internal sources of room heating and cooling, and draughts, are linked to the spread of airborne clouds of contaminant, e.g. those released in a human breath. The project aims to develop this understanding and thereby to determine whether the airborne spread of pollutants can be mitigated by natural and mechanical ventilation strategies or a hybrid strategy. The approach will be to develop and validate simplified mathematical models of these situations, ultimately to enable rapid prediction of the spread of pollutant clouds in ventilated spaces, both single spaces and connected spaces, for use in decision-making and in developing strategies that mitigate pollutant spread whilst maintaining comfortable environments.Relates to the following EPSRC Research Areas: Fluid Dynamics and Aerodynamics, Built Environment

随着全球走出2019冠状病毒病疫情，采取措施确保建筑物内居住者的健康和安全（由于空气污染物）可能比以往任何时候都更加重要。尽管在过去的20年里，我们对房间通风的理解有了很大的进步，但对于室内加热和冷却以及气流的内部来源所产生的运动的影响如何与空气中污染物云的传播（例如，人类呼吸中释放的污染物）联系在一起，我们的理解从根本上是有限的。该项目旨在发展这种理解，从而确定是否可以通过自然和机械通风策略或混合策略来减轻污染物的空气传播。该方法将开发和验证这些情况的简化数学模型，最终能够快速预测通风空间中污染物云的传播，包括单个空间和连通空间，用于决策和制定在保持舒适环境的同时减轻污染物传播的战略。涉及以下EPSRC研究领域：流体动力学和空气动力学，建筑环境
