Ventilation & Environmental Flows
We have a comprehensive range of software and tools to design, simulate and assess different heating, ventilation and Air-Conditioning
Systems (HVAC) as well as environmental flows. During the COVID-19 pandemic, we used our expertise in a number of projects to help improve ventilation in different settings and also developed a numerical framework for testing biosensors capable of detecting different variants of viruses. In addition, we have conducted projects related to atmospheric flows, wind microclimate and pedestrian comfort and Urban Heat Island (UHI) effects.

Our Ventilation Assessment & Design Expertise


Using advanced Computational Fluid Dynamics (CFD) techniques, we have unique expertise in modelling and simulation of different ventilation systems including both natural and mechanical ventilation systems (e.g. supply/extract, heat recovery, extraction, air conditioning, fan coils, chilled beams and etc). Our simulation tools allow a meticulous assessment of the current ventilation system to obtain key parameters such as air freshness level (air residence time), air change per hour, particle extraction, temperature/pressure/velocity measurement, etc. This would enable us to assess the performance of existing ventilation systems in minimising the risks of airborne transmission of COVID-19 (SARS-CoV2) in any workplace. We also have experience in optimisation vaccine storage and refrigeration. Below are some recent examples of our simulation and design projects for a wide range of HVAC systems.

Case Studies

St. Richard’s Hospice CFD HVAC.jpg
Ventilation Systems & Covid-19 

Simulation of the  ventilation system in the award-winning new hospice building and risk assessment of COVID-19 under different scenarios and evaluating the impact of natural ventilation in spread of the virus for different occupancy patterns. Sector: HVAC/ Healthcare | Company: St Richard's Hospice.

Atrium Ventilation Design

Design and CFD modelling of the internal ventilation system of a large academic building in Manchester, where two  novel atria were designed and tested, utilising innovative heat transfer concepts.

Sector: Building Services| Company: MMU Facilities, UK.

Smoke Extraction Systems

CFD modelling to assess the effectiveness of smoke extraction from the carpark for a large building and its effects on the building. The model used accurate regional wind data an smoke was modelled by chemical species.

Sector: Building Services | Company: McAleer&McGarrity, Ireland.

Local Exhaust Ventilation

CFD-based shape optimisation of a Local Exhaust Ventilation (LEV) system. The optimisation was based on suction force as well as the number of particles travelling through the bellmouth.

Sector: Manufacturing | Company: AEM Products, UK.

Ultra Clean Room Simulation

CFD simulation of different ventilation systems and designs, for different industries, with particular expertise in modelling complex and novel designs for hospitals, workshops and laboratories. 

Sector: Healthcare | Company: Medical Air Technologies, UK.

Domestic Heating Design

Simulation and design optimisation of an innovative device used to divert heat from radiators towards windows with an aim of reducing energy loss through the windows and removing condensation/mould by creating a thermal boundary layer.

Sector: Energy | Company: Thermocill, UK.
