Thermal & Energy Management
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
The overall complexity of the powertrain has significantly increased with the need to understand the detailed interaction of the individual sub-systems across a range of attributes. Improving fuel economy while reducing pollutant emissions implies deep engineering investigation to optimize powertrain energy management strategies, and ultimately how it impacts vehicle performance.
Enteknograte proposes a full-vehicle simulation approach provided by 3D CFD simulation tools, along with our engineering services capabilities, to enable full traceability of powertrain energy balance.
Being able to have complete understanding of transmission performance and losses, engine air intake and in-cylinder combustion, engine thermal management strategies and the impact of all these subsystems choices on the global vehicle performance during integration is crucial.
We analyze system-level thermal management of vehicle component, including underhood, underbody and brake systems, and design for heat shields, electronics cooling, HVAC, hybrid systems and human thermal comfort and covers a wide range of Industries like Automotive, Aerospace, Oil and gas, marine, medical devices, heavy engineering and Industrial and consumer appliances.
Our Finite Element (LS-Dyna, Ansys, Abaqus) and CFD simulation (Siemens Start-ccm+, Ansys Fluent , Ansys CFX and OpenFoam) for heat transfer analysis, thermal management, and virtual test process can save time and money in the design and development process, while also improving the thermal comfort and overall quality of the final product.
Why we use Coupled FEA-CFD?
Finite Element Analysis (FEA) is a powerful and well recognized tool used in the analysis of heat transfer problems. However, FEA can only analyze solid bodies and, by necessity thermal analysis with FEA is limited to conductive heat transfer. The other two types of heat transfer: convection and radiation must by approximated by boundary conditions. Modeling all three mechanisms of heat transfer without arbitrary assumption requires a combined use of FEA and Computational Fluid Dynamics (CFD).
With using CFD based design optimization solutions serve as an important link for our clients to realize their product promise right from concept to realization. Our team of CFD engineers in conjunction with experienced FEA Engineers for FSI and complicated industrial multiphysics problem is delivering solutions to major engineering verticals globally.
