Model & approach
- Reduce the CAD model to flow- and heat-relevant detail
- Represent engine, hydraulic and exhaust heat sources and cooling-air inlet conditions
- Evaluate velocity, pressure, temperature and the system-resistance curve
Project / Agricultural machinery
Full-vehicle simulation of an engine-cooling system
A full-vehicle model combined heat balance, airflow and system resistance to support preliminary cooling-component selection.
Engineering question
Engine-bay cooling had to be assessed both without ram air and with the vehicle moving.
Boundary conditions
- Stationary operation and slow vehicle movement
- Charge-air/water and oil coolers within the cooling concept
- Simplified full vehicle with project-specific openings and installations
Results of the assessment
- The simulation exposed inlet paths, pressure zones and temperature fields in the engine bay.
- The second operating point enabled a comparison of ram-air influence.
- A system-resistance curve was derived from airflow and pressure loss.
Engineering consequence
The results supported preliminary selection of fans and fan drives.
Context
The sizing applies to the operating conditions assessed; final component selection and physical testing remain separate development steps.
