Computational Fluid Dynamics (CFD) Expertise
Overview of some of the areas where we have collaborated with our clients
Our team has developed a diversified toolset in computational fluid dynamics (CFD) analysis since the inception of Optumatics. We have gained exposure to a multitude of analysis problems from various industries:
Internal Combustion Engines
Transient simulation of flow inside internal combustion engines, fuel mixing, combustion modeling, emissions modeling, knock detection and conjugate heat transfer analysis (solid engine block with in-cylinder fluids and cooling circuit fluids).
External flow simulation around vehicles are essential for prediction of lift and drag coefficients for vehicles, in addition to prediction of the velocity field and heat transfer coefficient across the different parts of the underbody for thermal management considerations.
Simulation of flow inside turbomachinery can be used to predict how design changes will affect the device performance map (e.g., surge line in compressor map) as well as help designers understand and reduce losses (e.g., recirculation, friction, etc.) and ensure the optimal performance of their device.
Ensuring that various electronic component temperatures are within the safe limits is essential for component longevity. This requires accurate prediction of temperature and velocity distributions around critical components.
Oil Separator simulation
Analyzing the multi-phase flow patterns inside oil and gas systems can help make these systems more cost and energy effective.
Using CFD to predict the path along which smoke propagates in the case of a fire has become an essential aspect of modern building design.
Water Valve Systems
Characterizing the performance of a valve (e.g., pressure drop, loss coefficient, etc.) is important for the designers of fluid systems to ensure the safe and efficient operation of their device.
Finite Element Analysis (FEA) Expertise
Areas where we have previously worked
Our finite element analysis (FEA) team has worked with various clients on the following:
Wear analysis is needed in certain mechanical designs to ensure that certain mechanisms function as desired by the designer. It is necessary to predict the loss in materials in these mechanisms to be able to estimate how many wear-inducing occurrences (e.g., lock mechanisms) the system can withstand
Static Load Analysis
Depending on the engineering system being considered, understanding how the static loads cause the system to deform is needed as part of the system design. Therefore conducting static load testing is essential for predicting the stress and deformation and ensuring they are within acceptable range.
Dynamic Load Analysis
In engineering systems where the structure is exposed to dynamic loads, transient structural analysis is needed to ensure the structure can withstand the dynamic loads and that the the stresses and deformations are within the acceptable range.
Buckling and Stability Analysis
Stability analysis of structures under compressive loading is needed to ensure a structure's design loads are below its buckling load. Obtaining estimates for a structure's buckling load and the different buckling modes can be done using FEA.
Fatigue and Fracture Analysis
Fatigue analysis is needed when designing structures that undergo repeated loading and unloading (i.e., load cycles) to determine the number of cycles after which fatigue failure occurs due to initiation and propagation of cracks.
Multibody dynamics simulation is needed in mechanical design to estimate the load a subcomponent in a mechanism is exposed to during transient operation. Multibody dynamics analysis can be thought of as a pre-requisite for dynamic analysis and fatigue analysis.
Thermal Stress Analysis
In systems where structures are exposed both to external forces as well as thermal loads (e.g., engine piston, satellite structure, etc.) , the combined effect of these two factors needs to be incorporated when conducting structural analysis.
