Thermal Simulation for Tractors Using Exa PowerFLOW and PowerTHERM

Thermal Simulation for Tractors Using Exa PowerFLOW and PowerTHERM 

Off-Highway Equipment Simulation

Agricultural and construction equipment manufacturers are under pressure to meet increasingly stringent government emissions standards. The challenge is the methods of reducing NOx and particulate matter, such as exhaust gas recirculation, diesel particulate filters, and selective catalytic reduction, often lead to a higher demand on the engine cooling system.

These design challenges – cooling airflow, thermal management, fan noise – are heavily influenced by complex fluid flows. Design elements, including the grille opening, heat exchangers, and cooling fans, and their size and placement needs to be optimized to ensure maximum cooling flow within the engine compartment. Passenger comfort is also paramount to the consumer and must be considered throughout the design process.

Finding the right balance between these values is the challenge in off-highway vehicle design. Understanding how design choices impact the overall performance of the vehicle is essential early in the design process. Exa’s PowerFLOW and PowerTHERM solutions perform simulations that accurately predict real-world transient conditions on the most complex geometry. 

In this video, see what thermal simulation looks like in Exa’s PowerFLOW and PowerTHERM solutions on a Deutz-Fahr 9 Series tractor. See how Exa’s thermal simulation solution creates complex and accurate visualization of thermal flow. Six different types of visualization are shown: air temperature distribution, streamlines colored by temperature, velocity magnitude flow, grilles air temperature and surface temperature.
