What is Computational Fluid Dynamics (CFD)?

Computational fluid dynamics (CFD) uses numerical models to predict how liquids, gases, heat, particles and chemical species move through or around a product, process or environment. A real system is converted into a digital domain, divided into a computational mesh and solved against the governing conservation equations. The result is a detailed view of quantities that are difficult, costly or unsafe to measure directly, including velocity, pressure, temperature, concentration, residence time and heat transfer. Used well, CFD does more than create visualisations: it explains why a system behaves as it does, tests credible alternatives and gives engineers evidence for design, safety, compliance and investment decisions.

Mansim is one of the most advanced companies in the world in developing CFD techniques and applying them to complex industrial problems. Originating from the ManchesterCFD team at University of Manchester, the CFD team at Mansim has an international reputation in accuracy, reliability and speed of computational simulations, evident from our awards, peer-reviewed publications and credentials of our team members.

When is CFD Used?

CFD-Expertise_edited.png
Airflow and Ventilation Analysis

Assess air distribution, ventilation effectiveness, pressure control, contaminant movement and thermal comfort in buildings, hospitals, cleanrooms, industrial facilities and data centres. 

1 (8).png
Thermal Management 

Identify hot spots, recirculation and cooling limitations in equipment, electronics, data centres, HVAC systems, furnaces and energy infrastructure.

1 (3).png
Product Design Optimisation

Compare geometries and operating conditions to improve performance, reduce pressure loss, increase efficiency and shorten physical prototyping cycles.

1 (1).png
Industrial Process and Multiphase Flow Analysis

Analyse mixing, drying, filtration, sprays, particles, bubbles, evaporation and reacting flows in vessels, reactors and manufacturing equipment.

1 (12).PNG
Aerodynamics, Wind Microclimate and Environmental Flow Modelling

Evaluate aerodynamic forces, wind microclimate, exhaust dispersion, plume behaviour and external airflow around products, buildings and infrastructure.

Our Approach

01

Define the Challenge

We clarify the engineering question, performance criteria and required scenarios.

02

Review Inputs

We assess CAD, drawings, operating data and available measurements.

03

Build the Model

We prepare the geometry, mesh, boundary conditions and selected physical models.

04

Verify and Validate

We check convergence, mesh sensitivity and agreement with available evidence.

05

Test and Optimise

We compare operating conditions, design options, failure cases and mitigation measures.

06

Report Recommendations

We deliver clear findings, visualisations and practical engineering actions.
