We provide a range of services for solving problems related to computational fluid dynamics and flow measurements in cavitating flows.

Performing CFD analysis, development of new CFD modules and licensing of our specialised CFD software may give the solution you need. Fluid dynamics analysis can be supported by instrumentation, flow measurements and testing that can be used to design a prototype system or obtain specific validation data for CFD model verification.

Our Services

Outsourcing some or all of your specialised flow modeling or problem-solving needs may make sense for your company. The size and workload of your engineering staff and in-house expertise may force you to ask the help of specialists. We have the experience of specialists consisting of CFD analysts, software developers and experts in CAD and mesh generation. We provide a wide range of services from complete problem-to-solution analysis to the development of customised software applications and modeling approaches. For more information, or a confidential discussion contact us.

Licensing of specific flow modules of the GFS flow solver is available. The code can handle arbitrary shaped geometries with moving boundaries. However, its strength is on the modeling of specific multi-phase flow systems such as nozzle flows, cavitation, sprays and flows with sharp interphases.

Complete Engineering Analysis

Our consultants can plan, manage, and execute a complete CFD project for you, ensuring that you get practical solutions within your schedule and budget. We add manpower and value to your CFD capabilities, complementing your in-house programs with our application-specific CFD expertise.

Custom CFD Methodologies

We can help to define the best CFD methodology for your design or problem-solving process. We can work with you to determine an optimal modeling strategy and train your CFD analysts to apply these methods.

Mesh Generation

We provide mesh generation services to CFD users who do not have the time, experience or resources to create their own computational mesh. Many companies find that use of mesh-templates can reduce turnaround time while maintaining full control over the end product.

Customised Software Development

We can take a general purpose software tool and customize it into a highly specialized tool suited to your needs. Our consultants have knowledge in physical and numerical modeling, model validation and analysis of the results. Proprietary CFD software can give you tremendous competitive advantage.

Customised Training

Our CFD consultants can work on one-to-one training of your CFD engineers to meet your needs. If you have a specific project to complete or if you simply want to explore the capabilities of our code, the expertise of our consultants can shorten your learning effort.


GFS solver can be licensed for use by third parties. Specific flow modules are available for incompressible laminar and turbulent flows with moving boundaries, nozzle flows, sprays, flows with sharp-interfaces, heat transfer, environmental flows etc. For more information on simulation modules available, for custom-made cases, prices and support please contact us.

We can design, manufacture, instrument and test specific nozzles and characterise the injected sprays using flow visualisation and laser diagnostics measurement techniques. Laser diagnostics and x-ray measurements can be performed in Engines, bearings and marine propellers. Experimental data can be also obtained to support the development and validation of existing or new CFD modules.

In addition to flow modelling, ICR has experience in basic and applied research, development and testing. Specialised measurements can be used to understand complicated flow phenomena taking place at very short time scales and to validate CFD models. We can provide services in the following areas:

Flow visualization

Understanding moderate to high speed phenomena such as bubble implosion and cavitation bubble dynamics, liquid droplet impact, gasoline and diesel spray development is facilitated with still video and high speed movie photography. Major components of this capability include CCD cameras with high magnification lenses, high speed cameras with frame rate up to 120,000fps and exposure time down to 5ns, various light illumination sources with short duration down to 20ns and supporting data acquisition equipment, instrumentation, and sensors including flow meters, pressure gauges and high frequency pressure transducers. Developed image post-processing tools based on Matlab applications and combination with CAD/CFD enable fast results and statistical information to be obtained.

Cavitation Tunnel

Testing of hydrofoils can be performed at TU Delft cavitation tunnel; See link for more information

Instrumentation of transparent Automotive injectors

internal flow visualisation: Mini-pressure transducers, transparent quartz windows and needle lift sensors can be instrumented to various automotive injectors. That can allow for full characterisation of the injector operating characteristics simultaneously with visualisation of the internal flow under realistic operating conditions of automotive fuel injection systems where pressures can reach 2000bar.

Scale-up nozzle models

Experimental investigation of cavitation formed inside automotive injectors can be performed using scaled-up models manufactured from perspex. Fully transparent nozzles or other hydraulic devises allow for flow visualisation at the areas of interest. Manufacturing of complicated geometries is done with precision using CNC machines. Testing can be done with water or with a special mixture of hydrocarbons having the same refractive index at a given (controlled) temperature. Both flow imaging and quantitative flow measurements (LDV) can be obtained.

Laser Diagnostics

Laser Doppler velocimetry (LDV) and particle image velocimetry (PIV) measurements can be used for the characterisation of the mean and turbulent flow field of various flow types, such as in nozzles and internal combustion engines. Additionally, phase Doppler anemometry (PDA) point measurements provide simultaneously the droplet size and velocity of the spray plume. Laser induced fluorescence (LIF) can provide the liquid and vapour distribution of evaporating sprays. Such measurements can be used for characterising temporally and spatially sprays and providing validation data for CFD models.
