Research and development in fluid mechanics and CFD simulations

PLS Fluid Dynamics is an engineering consulting company specialized in Computational Fluid Dynamics. We provide CFD studies and a complete consulting service in all fields of fluid mechanics.

Our expertise and our resources allow us to support you from the edition of the specifications to the manufacturing of a prototype through CFD studies, mechanical design and experimental tests.


Aerodynamics modeling allows us to precisely study the air flow around a body in order to improve its design. Data from our simulations range from computations of the pressure coefficients to the stream of velocity profiles and boundary layers take-off.

Heat transfers

CFD allows to simulate all kind of heat transfers (conduction, convection and radiation). We help you size your equipment (heat exchangers, furnaces…) in order to reach the ideal working point.

Mechanical design

We can also act directly on the design of the studied mechanical system according to the simulation results. We are able to provide a full consulting service in mechanical design up to the edition of the design drawings of your system.

3D printing

In order to quickly carry out tests, we can 3D-print mechanical parts, providing a greater responsiveness for the prototype development process. It will be easier for you to visualize the effects of the improvements brought as result of the simulations.

Our skills allow us to help you on multiple and complex subjects such as reactive flows, multiphase flows (liquid-vapor, phase transitions, two fluids flows…) or chemical separation with semi permeable membranes...

Our approach

The framework is defined by our engineering department together with the customer. Then the complete study is carried out: the geometric model design, meshing, definition of simulation settings, computation, post-processing and analysis of results, report writing.

EasyPhi logoEasyPhi project

The EasyPhi project is a scientific instrumentation development project based on OpenHardware created by CERN. This development is currently a Franco-Swiss project, financed by European funds in order to bring this concept out of laboratories, to start an experimental development phase and to initiate its marketing.
