Mission
Our multiphysic expertise at your service
For the outsourcing of your R&D or preliminiary studies, we propose an extended know-how in multiphysic engineering.
With several years of experience in the fields of project management and numerical simulation, we aim to offer our clients the best pluridisciplinary support, for a fast and precise expertise from the design sketches up to the validated prototype.
Because investigating new products for new markts can be a difficult investment, we are here to provide you with guidance regarding the physic implied and the numerical tools you will need. Depending on your ressources and schedule, we propose analytic preliminary studies, in depth bibliography and full blown simulation based on latests scientific codes.
We are used to work with a wide spectrum of engineering themes, from the standard mechanics and fluid dynamics up to heat transfers, but also more exotic topics such as electromagnetism, beam optics, particle physics and irradiation.
In order to take charge of your whole design process, we can manage the manufacturer research and quotation, produce blue prints and follow the workshop process.
The R&D always imply a wide range of experts, so we are used to exchange with researchers, engineers, technicians, project leaders and commercials, understanding that a good communication is the keystone to any successful project.
Expertise
Mechanical engineering
Assembly resilience
The design of a mechanical assembly must abide to load limitations which depends of its intended use, constitutive materials, environment and eventual regulations. Wether it is aimed to be integrated in aeronautics, laboratory or everyday contexts, we validate their conformity by two kind of studies:
- Static studies, where the assembly is submitted to its own weight with minimal constraints or industrial conducts and tanks put under working pressure
- Dynamic studies are aimed to validate resilience when considering a transported assembly submitted to accelerations, windows or tanks to partial void, motor parts to vibrations or industrial pipes to local fluid impact
Von Mises constraints and displacements are identified and compared to material characteristics, the resulting security margin is compared to regulator's requirement if applicable (industrial safety, aeronautics, automobile) or your specific needs (maximum elongation, airtightness, non-detachment, resonance). We then propose alternatives regarding assembly shape, material choice, its thickness or more efficient supports and fastenings positions.
Technical drawing
The very strength of any design office is to be able to transform a theoretical concept into a concrete and realistic assembly. The production of technical drawing is a step stone in this process and good quality blue prints ensures an efficient communication between designer and manufacturer.
We take care of your engineering drawings, whether they are destined to your own workshop or subcontractors, standard 2D for machining, isometric for industrial piping or even numeric formats for 3D printing.
Computational fluid dynamics
First thing first: about meshing
The complexity of flow studies is depending on several parameters such as speed, number of phases, geometries, density and pressure. Besides, exepected results must correlate with the time and ressources invested in it, planning correctly your CFD needs is of the essence.
Thus, meshing is a very important step in any project, we develop your numerical model from different data types (schematics, STEP, IGES, STL..) and, more than often, we adapt it your CFD needs, making it watertight, removing useless details, correcting overlaps, sometimes fully redrawing it if initial conception is lacking.
Turbulent and multiphase flows
We work on both laminar and turbulent flows, 2D or 3D, whether fluids are compressible or not. Results can be stationary if a stable solution is enough, or time dependent if a periodic behavior or a stabilisation period are of interest.
Furthermore, the flow can be different depending on the size and mass of the particle involved. Using the 'particle in cell' model, we can easily determine local concentration of aerosols both around and inside of sensor apparatus.
Aerodynamic efforts
We can do drag and lift calculations around any shapes provided and then determine efforts on fastenings in order to evaluate their resilience and safety criteria, proposing modifications if necessary.
Heat transfers
Coupled transfers
Heat transfers are of three kinds: conductive, convective and radiative. Often coupled, the purpose of any thermal study is to determine which one is preponderant and obtain its characteristic values.
Our studies cover these three phenomena, using both analytical and numerical methods, in order to obtain stationary or time dependent properties.
Complex configurations
We also take into account complex configuration involving different materials in an assembly, whatever the shape and size provided. Convection could be forced or natural, sources with fixed temperature or power and radiation model can be simplified if marginal or complex for more precision. .
Electro magnetism
Field maps
The design of an apparatus aimed at the production of an electric, magnetic, or both, field depends on its application, amplitudes and shapes of interest.
We propose 2D and 3D studies in order to determine potentials, currents and wiring needed. Once extracted, our field maps can then be integrated to your future simulations, generally to determine rotor efficiency or charged particle trajectories.
Assembly design
We can optimize the profile of the EM fields by modifying geometry, reshape coils or use safe guard rings. By the end of our study, we establish schematics, choose insulating or conductive materials and lastly determine pumping systems along with the power supplies you will need.
Particle physics
Beam optics
The setting up and exploitation of an accelerator in a scientific or medical context requires a good understanding of the particle behaviour as well as the user's chromatic needs.
We propose an expertise in beam dynamics, from the experimental line design and quotation up to its optical configuration for its daily use, but also the conception of tailor-made handling devices for specific uses. We are used to work for both low and high energies, intensities which imply important space charges to handle or neutralize, high emmittances and the hunt for reduced dispersion or achromatism at the focal point.
Radiation shielding and neutron physics
The understanding of ionizing particles and neutron physics are fundamental safety knowledges to have, not only for civilian energy production, but also in any laboratory which may store irradiated material or have to handle high energy beams.
We are able to evaluate criticity risks for stored materials, secondary radiations from beam handling or impact with targets. We are able to evaluate radiation type, dose rate, its localization and the shielding needed for a safe exploitation in conformity with regulation authorities.
Another interesting application for laboratories is plasma confinement. Whether it is for fundamental or applicative projects, we propose taylor made designs of RF or magnetic traps, their quotations and advices for their integration to beam lines.
Procedure
First contact
The first contact with our clients, by phone or email, is aimed to quickly study the adequation between their needs and what CADENE is capable to deliver in the defined time frame. If a collaboration is possible, we schedule a video conference where technical details are presented and discussed, covered by a non disclosure agreement if necessary.
Prepatory documents
Once the client needs are identified, a price offer is provided along with our general terms of sale. If accepted, our work will begin shortly. Depending on the project complexity, a full description document may be demanded, summarizing technical details, deadlines and contact information.Depending on the project nature, CADENE can provide exclusively encrypted reports and exchanges or working in an airthight networkless workstations if necessary.
Conduct of the study
CADENE ensures the deadlines are respected and the final technical report relevant to the initial specifications. The person designated as a point of contact maybe asked for further precisions during the working process. Depending on the project estimated duration or complexity, several meetings maybe demanded in order to correctly refocus workforce or redefine objectives.
Technical report delivery
The finalized technical report is delivered in paper or numerical formats and detailled during a final meeting. Complementary studies may be investigated without extra charge, as long as both sides agree on their relevance to the aforementioned objectives. CADENE engages its responsibility on the quality of the final report but is not allowed to monetize numerical or manufactured goods.
