Fluid Dynamics (CFD)

We have a dedicated computational fluid dynamics (CFD) team with extensive experience in both 1D and 3D simulation. With expertise in the fundamental mathematical modelling of fluid flow problems, including development of scripts and user routines, we offer a complete solution of Ansys CFD software, practical training and consulting.

Software and Consulting

Fluid flow issues occur in all sectors of engineering and can range from simple laminar pipe flow to complex multi-phase phenomena involving turbulence, rotating components, conjugate heat transfer and chemical reactions. We undertake a wide variety of computational fluid dynamics (CFD) consultancy and desktop study projects in most industries involving internal or external flows.

We have the flexibility to provide efficient fluid dynamics modelling solutions for all types and scale of equipment. This includes specialist strategies and software tools for Thermal ManagementWind Microclimate Assessment and other Building Physics.

Complementary to our other software and services for the Chemical & Process and Oil & Gas industries, we have significant experience in helping operators and equipment manufacturers upscale operations and increase throughput, efficiency & reliability through the adoption of CFD.

In addition to involvement in industrial mixing applications, our knowledge of modelling rotating equipment also extends to a range of turbomachinery applications, including centrifugal compressors and vertical/horizontal axis wind turbines.

Many software and consulting projects have featured valves, from regular pressure-flow characterisation and derivation of loss coefficients to detailed erosion predictions involving particle tracking and standard & modified wear models.

We have refined a technique for accurately modelling valve closure dynamics, combining CFD with spreadsheets and equations of motion. Another innovative approach has been developed to efficiently simulate the actuation torque performance of ball valves under mainly incompressible flows.

CFD is increasing being used to improve the environment in which we live, from improving pedestrian comfort and safety by mitigating adverse external wind flows induced by tall buildings and controlling pollution dispersion to optimising heating, ventilation and air conditioning (HVAC) for health and reduced energy consumption. We have significant project experience in these and other Built Environment applications.

Our Experience

There is no substitute for experience. We have been helping companies through our simulation consulting services since 1980, when the technology was still emerging and immature. 

Delivered by our large inhouse team of Chartered Engineers, Metallurgists and Physicists, we have undertaken in excess of 5,000 projects for start-ups, SMEs and multinational engineering companies.

More than Validation

We can offer you much more than a simple yes/no on whether your design, process or strategy is working well. Through our team of Chartered Engineers, we can generate insight, fresh ideas and potential solutions through experience, engineering knowledge, advanced analysis technologies and evolving optimisation methodologies.

This ranges from design guidance on machined & welded structures and support when developing products with 3D printing and other advanced manufacturing processes, through to specialist expertise on sealing & tribology and mentoring on design-for-reliability improvement programmes.

We’ve been using Ansys Fluent for complex releases. With hydrogen being quite a buoyant gas, we use Fluent to look at things like if we were to have a leak into our container, how would we expect the flow to move around the other cylinders. I don’t think you could model these things without CFD.


The work completed by Wilde has been invaluable in enabling us to design and build an optimised solution for clearing ice and snow with gusto. The computer modelling and subsequent report was very thorough offering options for alternative design.

Well executed, gives accurate level of confidence to start running simulations unaided... efficient …required minimal interface, but provided a pragmatic approach & interpretation (of results)

Halliburton (Red Spider Technology)

Wilde quickly understood the analysis that needed to be done on the Forward Tooling Assembly and used their FEA and CFD expertise to develop a new design to optimise the efficiency of the new vehicle within the required time scales.

Forum Energy Technologies

Wilde Analysis have been a pleasure to work with during this project, responsive to requests, delivering on time and at reasonable cost and providing good guidance as to optimal ways forward.

Moltex Energy LLP

Many thanks for your contribution. By your diligence you have enabled us to proceed with confidence.

Reviss UK

We have now installed the kiln jet and operated at nearly double the throughput. I’d just like to say thanks for the invaluable work that you carried out in helping us to hone the design to the final version that was installed and worked impeccably from day 1. It saved us a lot of trial and error on the production line with associated losses that would have been incurred.

Springfields Fuels

Excellent training provider in ANSYS CFD modelling with in-depth experience and expertise.

Rolls-Royce Marine

I was very impressed with the knowledge and tools available to us through Wilde and the accuracy of their first model predictions compared to my test results. This has already become a seminal piece of work that will underpin a significant future product development.


Wilde has always demonstrated a knowledgeable and professional understanding to our needs and have been able to quickly and thoroughly assimilate our requirements, and equally quickly produce the necessary results to support our design process and provide guidance on the solution(s) best suiting our needs commercially and technically.

MAHLE Industrial Filtration UK

Working with Wilde Analysis is a pleasure. They have the requisite skill, expertise and experience to contribute to the development of the solution. They are able to contribute at the research and development level and at the engineering design level, which is an important capability. As a business we have found them to be professional in their presentation and approach at all times.

Waters UK

The work provided enabled us to present high-quality information to the client, which is excellent, given that the building is going to be an iconic one.

Millwood House Consultants

... without the training & modelling techniques developed by Wilde, it would have been extremely difficult to predict the behaviour of the IR pre-heat oven. ... professional and exceeded the requirements set in the original brief, with extensive communication via meetings, e-mails and telephone conversations.

Glasscoat International

Thank you for the very speedy delivery on our project. In general I find Wilde very responsive to our needs and this is very much appreciated!

Evoqua (atg UV Technology)

Wilde was instrumental in the modifying of our existing design to ensure that performance met the specific & stringent customer requirements on this particular project. Without the modelling capabilities & advice/service provided by Wilde we would not have been able to identify the limitations in our current design in house, nor have been able to implement the required design changes that the CFD process identified as being required.

Northvale Korting

We always appreciate Wilde’s approach as working with them is very beneficial for us, both in terms of project costs & knowledge transfer. They are very open about the results, barriers & difficulties involved, & do their utmost to make sure the models are validated, which not many other companies would do. Wilde go to great lengths to produce the accurate results we need, that’s why we have developed a successful working relationship.
