Development and validation of a Thermal Simulation Model for Li-ion batteries in HEVs/PEVs
This presentation will report some of the conclusions from the 2 year project including Porsche, GM Opel and Daimler. The project is managed and led by the Automotive Simulation Centre Stuttgart. The project is a rigorous study into the application of simulation technology to a previously designed lithium ion battery pack. The presentation will feature comparisons of test work and simulated results at both the cell and module level.
Simulation of noise in HVAC ducts
For an automotive HVAC system the noise created and perceived by the occupants is an important factor that has to be accounted for. The system has to create an environment which provides a sufficient amount of cooling or heating to keep the occupants comfortable, but not at the detriment of excessive noise due to the air flow. Therefore the HVAC duct system has to be designed to deliver the air efficiently and quietly into the cabin. To achieve such desirable conditions the system has to be designed early in the vehicle programme using CAE techniques. CFD methods are maturing in the area of...
Battery Design Studio® - an update
Several important capabilities of Battery Design Studio® will be presented including the capability to simulate three-dimensional pouch cells, current distribution in spiral cells and concentration-dependent, solid-phase, diffusion coefficients. These capabilities enable battery designers to size current collectors and tabs for the large lithium-ion cells used in automotive applications. Further, the enhancements to the physics-based models improve their capability to simulate the very high-rate behavior of lithium-ion batteries. Lastly, the road map for upcoming capabilities of the software...
STAR-CCM+ captures the acoustics buried in turbulence
DENSO Marston has been undertaking a 5-year joint R D project called ‘Validation of Future Non-Road Machines’ (VORM), co-funded by the UK government's Technology Strategy Board and One Northeast. In this project STAR-CCM+ has been extensively used as a tool to model the machine cooling system and to optimize its components. Methodology and limitations of coupling a STAR-CCM+ single stream heat exchanger model with the 1D vehicle thermal modelling program KULI were firstly explored. STAR-CCM+ dual stream heat exchanger model results were then used as benchmarks to develop a KULI methodology...
Macrohomogenous Li-Ion-Battery Modeling - Strengths and Limitations
With the advent of vehicle electrification, driven largely by advances in Li-ion battery technology, there is an increasing need for the type of predictive simulation tools that are commonplace in the virtual vehicle development process for classical ICE-propelled automobiles, such as crash, aerothermal and combustion simulation. Such tools are necessary in order to make the overall development effort and cost of electric traction systems competitive by reducing the test and design loops. Aiming to establish a multiscale simulation process chain bridging material, cell, module/component and...
The aerodynamic development of the 2011 Ford Ranger Global Compact Pick-Up with STAR-CCM+
Cutting CO2 emissions and improving fuel economy is a primary focus for the entire global product line-up at the Ford Motor Company. Optimizing the aerodynamics of the vehicle is a key contributor to achieving those fuel economy targets. To this end, the Ford Ranger provides a unique set of challenges for the aerodynamicists and designers as they balance the constraints of class leading design with the clear functional needs of a Global Compact Pick-Up. Adopting a systems engineering approach that integrates aerodynamics in an interdisciplinary and collaborative design and development process...
