Development of Analytical Models for Hybrid Ventilation Systems

随着世界走出Covid-19大流行，采取措施确保建筑物内居住者因空气污染物而健康和安全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取得了重大进展，但从根本上来说，我们对室内供暖和制冷以及通风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）联系在一起的理解仍然有限。该项目旨在发展这种理解，从而确定污染物的空气传播是否可以通过自然和机械通风策略或混合策略来缓解。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（包括单个空间和连接空间）中污染物云的扩散，用于决策和制定策略，以减轻污染物扩散，同时保持舒适的环境。涉及以下EPSRC研究领域：流体动力学和空气动力学，建筑环境

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
