Computational Fluid Dynamics (CFD)  

Delivering solutions to fluid flow problems in an easy to use, intuitive and responsive environment for SME’s, global corporations, academia and start-ups alike.

 CFD Case Studies: Ventilation, Smoke, CO, Thermal Comfort

Thermal Management of a Pharmaceutical Warehouse

Medication needs to be stored at a specified temperature to prevent the product getting spoiled. In that regard, CFD was used to model and design an HVAC system that could regulate the temperature and humidity as required.

NSW Classrooms: Thermal Comfort & PMV

ANSYS CFD’s ability to model heat transfer meant that it could be used to determine the  vent locations and sizes to obtain thermal comfort for classrooms and a library within a school in NSW.

Evacuating Leaked Chlorine Fumes for Operational Health & Safety

Transient CFD simulations were run to assess the effectiveness of the ventilation system to remove the build-up of chlorine in a plant room, within a specified regulatory time.

Vent Sizing and Temperature Control for Sydney Opera House

Before installing the new HVAC system, CFD was used to ensure that the underfloor and rear vents still maintained the desired temperature distribution in the arena, even under different seating configurations.

Tracking Formaldehyde in Laboratories

Operational Health & Safety has strict limits on the allowable build-up of toxic fumes, such as formaldehyde in laboratory settings. CFD was required to ensure the table and room vents sufficiently ventilated the room.

Thermal Management of a Warehouse

In modelling the heat transfer from the environment, CFD took into account the rotational effects of the fan, swirl of the diffusers, solar radiation on the external walls and conduction through the thickness – all in a single simulation.

Interaction Between Building Façade, Louvers & Plant Room Exhaust

Using ANSYS CFD, architects and designers were able to revise the design of the façade to prevent exhaust gas from the chillers to be redrawn into the plant room.

Positioning of Air Conditioning Units on A Rooftop

When installing rooftop equipment on a building, consideration needs to be given to the seasonal wind and orientation of the equipment; CFD was used to ensure hot exhaust from one unit wasn’t ingested into the intake of another.

Pathogen Transmission in a Hospital Ward via the HVAC System

Health officials in the state of Victoria found benefit in simulation, when CFD highlighted the propagation of a sneeze or cough within a room and its transport into adjacent rooms, not via contact touch, but via the HVAC system.

CO Tracking in Car Parks for AS1668 Compliance

Starting from 2D CAD, our CFD tool has allowed designers (with zero prior CFD knowledge) to be AS1668 certified on their car park ventilation design in less than 1 week.

Modelling Jet Fans in a Car Park for AS1668 Compliance

Our CFD tools can include the details and affect of jet fans within a car park, allowing a designer to assess the location and number required.

Thermal Management of Electronic Enclosures

Data centres, plant rooms & switch rooms, all generate a large heat load from the equipment; CFD allows a user to assess the various placements and sizes of these active cooling mechanisms.

Thermal Management of a Warehouse

Engine test rooms see a build-up of diesel fumes during regular operation; CFD was used to design an HVAC system that removed pollutants in a prescribed time.

From Diffuser Design to PMV, PPD and Thermal Comfort

Understanding the quality and trajectory of the air existing a diffuser is important to a manufacturer, as it helps them advise on how many such diffusers are required to maintain thermal comfort within a living or working space.

Rail Tunnel Thermal Stratification

The air conditioning exhausts from a stationary train within a tunnel can cause thermal stratification within the enclosed space. CFD was used to assess how hard the tunnel HVAC system has to work to evacuate these exhausts.

Sydney’s West Connex Tunnel System

Given that vehicle exhaust fumes can be vented via stacks into nearby urban areas, CFD was used to ensure the equipment was sized correctly and the pressure losses within these secondary tunnels was not outside allowable limits.

Fire and Smoke Ventilation in Tunnels

By importing fan curves directly from the supplier into CFD, zonal evacuation in a tunnel can be assessed. Furthermore, the effectiveness of the fans, based on their numbers and locations in relation to tunnel geometry can also be studied.

Fan Sizing For Mine Ventilation

Using actual terrain obtained from laser scans, CFD assessed the smoke concentrations in different parts of the tunnel, the corresponding lack of visibility and also how long it took the fans to evacuate the smoke to allowable levels.
