Vehicle Thermal Management Simulation

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

Extending from steady state to transient simulation allows engineers to investigate the real conditions of vehicle driving cycles. The processes we use are efficient utilizing real world transient simulation including FEA-CFD coupling if needed. The majority of virtual vehicle thermal management utilizes the coupling of FEA Solvers like Abaqus, Ansys, LS-dyna , Nastran and MSc Marc to a computational fluid dynamics (CFD) solver like MSC Cradle, Siemens Star-ccm+ and Ansy Fluent. This technique can significantly reduce the turnaround time by creating a cost and time efficient process that utilizes the strengths of each solvers.

CFD heat transfer analysis: CHT, one-way FSI and two way thermo-mechanical FSI

The management of thermal loads and heat transfer is a critical factor in the design of many mechanical products and systems. Enteknograte’s Engineering Team provides a comprehensive Steady-State and Transient CFD Thermal Analysis & Design services Flow Simulation. CFD Thermal Analysis extends the capability of FEA thermal analysis by replacing the simplistic convection boundary conditions with direct calculations of the heat transfer coefficients based on the fluid flow properties and is often referred to a conjugate heat transfer analysis.

Once the flow solution is complete and the temperature distribution in the solid bodies has been computed then the effects of thermal expansion, thermal stress, fatigue, creep and thermally induced buckling can be calculated in detail.  Effects such as temperature dependent material and fluid properties, contact conditions and other sources of non-linearity can be modeled in detail, regardless of the complexity of the system.

Passenger Thermal Comfort

Our engineers use FEA/CFD tools in co-simulation with 1D system modeling softwares for develop and test control strategies, and study the impact of the system on overall vehicle thermal management, analyze thermal interactions between air conditioning loops or heat pump systems, the cooling system, additional heaters, and the cabin or vehicle interior, and control the cabin cool down or heating processes.

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).
