TIME DEPENDENT SIMULATION METHODS FOR VEHICLE THERMAL MANAGEMENT
The present work implements 1-D and 3-D unsteady CFD based simulation tools in vehicle design process and shows a heavy hybrid diesel electric vehicle thermal management system with multiple under-the-hood and HVAC loops showing the potential of next generation highly efficient, cheap, light weight and environmentally friendly HVac systems.
Abstract
ABSTRACT Increasing power requirements along with weight and space constrains requires implementation of more intelligent thermal management systems. The design and development of such systems can only be possible with a thorough understanding of component and system level thermal loads. The present work implements 1-D and 3-D unsteady CFD based simulation tools in vehicle design process. Both under-the-hood cooling and HVAC systems are simulated in various operating conditions on a HPC Computer Cluster. System variables are optimized with gradient based BCSLIB and SciPy optimization libraries. The simulation results are compared and validated with experimental tests.
