Computational Fluid Dynamics Services for HVAC, Cooling & Thermal Comfort

Advanced CFD Solutions for the Built Environment

Computational Fluid Dynamics (CFD) is a powerful engineering tool that predicts how air, heat, smoke, and pollutants move in real-world spaces. At Lava Consultants, we use CFD to help design teams, developers, and contractors validate designs, optimise performance, and meet authority requirements. Our CFD services cover a wide range of applications including chiller yard analysis, HVAC CFD, indoor cooling CFD, outdoor cooling CFD, thermal comfort analysis, car park ventilation analysis, duct flow analysis, and air distribution analysis.

By applying advanced modelling techniques, we give our clients the confidence that their projects will achieve both safety and efficiency goals while complying with local authority standards such as Dubai Civil Defence, Abu Dhabi Civil Defence, and Qatar Civil Defence.

Chiller Yard CFD and Cooling Tower Analysis

In hot climates such as the UAE, Qatar, and Saudi Arabia, cooling infrastructure is under constant pressure. Poor design of chiller yards and cooling towers often leads to hot air recirculation, reduced cooling capacity, and high energy consumption. This is where Chiller Yard CFD plays a vital role.
Through detailed chiller yard analysis, we simulate airflow patterns, temperature distribution, and recirculation effects. This helps engineers and contractors identify design weaknesses early and implement solutions such as equipment repositioning, barrier installation, or fan optimisation.
We also conduct Cooling Tower CFD studies, which assess plume behaviour and airflow interaction between towers. This ensures that cooling towers perform at peak efficiency, delivering reliable cooling performance while reducing operational costs and extending equipment life.

HVAC CFD and Air Distribution Analysis

Modern buildings rely on Heating, Ventilation and Air Conditioning (HVAC) systems to ensure a safe and comfortable environment. HVAC CFD analysis gives detailed insights into airflow, temperature variations, and ventilation effectiveness.
A critical part of this service is air distribution analysis, which examines how supply air is delivered to occupied zones. By testing different diffuser layouts, duct routing, and system configurations, we ensure that conditioned air is distributed evenly across the space. This avoids common problems such as hot spots, over-ventilation, or air stagnation, all of which can lead to discomfort and wasted energy.
With our expertise, design teams can optimise system layouts, reduce energy costs, and ensure compliance with both regional codes and international standards.

Indoor Cooling CFD

Indoor Cooling CFD focuses on air-conditioning performance in enclosed spaces. Using advanced 3D models, we simulate airflow from diffusers, duct systems, and exhausts, identifying areas of uneven cooling.
This type of analysis is vital for complex facilities such as data centres, hospitals, exhibition halls, and theatres. By conducting duct flow analysis alongside indoor cooling studies, we can pinpoint inefficiencies in duct sizing, airflow velocities, and pressure drops, helping ensure efficient and reliable performance across all operating conditions.

Outdoor Cooling CFD

In hot-climate regions, outdoor comfort is a growing priority. Outdoor Cooling CFD evaluates how strategies such as evaporative cooling, air curtains, and misting systems perform under real-world wind and temperature conditions.

These studies help optimise airflow in stadiums, courtyards, public plazas, and semi-open areas. Designers can use CFD results to place fans, shading devices, and vegetation effectively, ensuring that outdoor environments remain usable and comfortable while keeping energy use under control.

Car Park Ventilation Analysis

Car parks present unique safety challenges due to smoke, carbon monoxide, and heat build-up during both normal and emergency conditions. Car park ventilation analysis with CFD allows us to test the performance of jet fans, ducted systems, and natural ventilation strategies under fire and non-fire scenarios.

We evaluate smoke propagation, visibility levels, temperature distribution, and pollutant concentrations. This ensures compliance with local Civil Defence requirements while providing safe evacuation routes and reliable access for firefighting. Our car park CFD studies reduce design uncertainty and support authority approvals by demonstrating system effectiveness in realistic scenarios.

Thermal Comfort Analysis and Thermal Comfort CFD

One of the most important outcomes of CFD studies is understanding thermal comfort — how occupants actually feel in a space. Poorly designed HVAC or cooling systems can cause discomfort, productivity loss, and dissatisfaction.

Our Thermal Comfort Analysis combines Thermal Comfort CFD simulations with recognised international standards such as PMV (Predicted Mean Vote) and PPD (Predicted Percentage Dissatisfied). This provides accurate predictions of how people will experience the space under different design conditions.

Whether for office towers, residential developments, schools, or shopping malls, our thermal comfort CFD studies ensure spaces are both energy-efficient and comfortable for occupants.

1. What is Computational fluid dynamics (CFD)?

 Computational fluid dynamics (CFD) is a simulation technique that analyses airflow, heat transfer, and ventilation to optimise building performance and thermal comfort.

 Cooling Tower CFD simulates airflow and heat rejection in chiller yards and cooling towers, helping optimise layout, reduce energy consumption, and improve reliability.

HVAC CFD analyses ductwork, air distribution, and pressure drops to ensure efficient airflow, thermal comfort, and energy savings in indoor environments.

 Indoor Cooling CFD evaluates airflow, temperature, and pollutant dispersion inside enclosed spaces, ensuring occupant comfort and compliance with performance standards.

Thermal Comfort Analysis simulates temperature, air velocity, and humidity in spaces like offices, auditoriums, and residential buildings to optimise HVAC design and improve occupant wellbeing.

 Outdoor Cooling CFD predicts airflow and heat patterns around buildings, helping architects design natural ventilation strategies and reduce urban heat effects.

 Tunnel Fire Modelling uses CFD to simulate smoke, heat, and ventilation performance in tunnels, ensuring safe evacuation, compliance with fire codes, and optimal ventilation design.
