Thermal Analysis: CFD and FEA Based Simulation
ESimLab’s Engineering team with efficient utilizing real world transient simulation with FEA – CFD coupling if needed, with FEA Solvers such as Abaqus, Ansys, LS-dyna, Nastran and MSc Marc and computational fluid dynamics (CFD) solver like Siemens Star-ccm+ and Ansy Fluent for advanced Thermal simulation and have clear knowledge about the assumptions and simplifications that must be made to get results with required accuracy.
The effects of heat and thermal management of structures is more and more critical as performance limits are pushed further by the need to have lighter, smaller and more efficient designs. Convection, radiation and conduction loads are obvious, but the need to include the effect of power losses and thermal energy from friction and external sources such as pipe flows means that analysts need to have more tools at their disposal to simulate thermal models accurately. 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.

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).
An underbody and exhaust system modeling effort is a complex thermal management challenge, but ESimLab engineering team uses Ansys Fluent, Ansys CFX and Siemens Star CCM plus+ in coupled with Structural Solvers to solve this issue daily. Our team establishes an efficient process for modeling the exhaust system in a realistic, time-dependent environment. CFD and FEA simulation of the systems, allows our team to make design changes to protect unwanted thermal load on critical components. This could reduce overall vehicle development costs, reduce your testing expenses.
Exhaust Thermal Modeling
Vehicle exhaust systems are subject to intense thermal loading. It requires both careful methodology and engineering experience to accurately predict their shielding, underhood, and underbody temperatures. Whether your goal is mass reduction, improved manifold shielding, or developing diesel particulate filters, the fastest, most cost-effective way to a reliable solution is working with Advanced CFD and FEA tools combining with ESimLab engineers experience and innovative simulation procedure. ESimLab engineering team includes experts from within the automotive industry that have many years of experience developing solutions to multiphysics and heat transfer problems. From optimized heat shield design to full-vehicle simulations of hot soak driving cycles, our engineers provide you with the most cost-effective and comprehensive simulations.
Brake Thermal Modeling
our engineers are well-prepared to employ FEA and CFD tools to capture all modes of heat transfer from the system: radiation, conduction and convection. Our simulation methods include all transient braking events whether that is a high-speed track test or any transient customer driving profile. Our engineers can help you identify ways to reduce the mass of your system while improving thermal performance or exploring highly wear-resistant materials. Using FEA and CFD softwares, ESimLab engineers quickly produce accurate models of brakes, clutches, or other friction devices. We deliver comprehensive engineering reports, and in-depth aero-thermal analysis for the entire brake system.
HVAC/Climate Control Analysis
Climate control systems are often subjected to different thermal loads and require a conjugate heat transfer analysis. Most of systems have both environmental loads and electric dissipation loads and the purpose of many climate control systems is human thermal comfort. With using advanced Thermal analysis tools we can test the efficacy of passive thermal designs and energy-saving devices, without sacrificing human comfort. ESimLab provides both system-level and building-level analysis. From study of a window design to a full system analysis of HVAC loading requirements, our experience and efficiency are leveraged to a cost-effective solution.
Climate Control System Design
ESimLab engineers place virtual buildings, vehicles, and human models into simulated natural environments with specific global positions, real weather data, and, in some cases, virtual human thermal models. Simulating the total energy balance of the building or vehicle over time, including the performance of the climate control system, we predict the temperatures of the exterior and interior spaces.The temperatures of the human body segments and body core are simulated in response to the building or vehicle environment, including solar transmission through windows onto the human model. The results of such analyses allow improvements to thermal performance of engineered systems with lower energy consumption by HVAC systems.
