Performing landing operations of a helicopter or a UAV (Unmanned Air Vehicle) on the helideck of a battleship is a critical situation for both the "pilot" of the air-vehicle and the crew of the ship. A detailed understanding of the flow structure and turbulent fluctuations is therefore necessary. Taking into consideration the very detailed superstructure of the complete ship, CD-adapcos engineering software such as STAR-CCM+ can be used to predict turbulence fields. Background Reconnaissance is one of the main tasks of the German Navy. A UAV will ensure identification of objects beyond the...
Impact of STAR-CCM+ v7.0 in the automotive industry
The number of automotive engineers using STAR-CCM+ for vehicle simulation has been growing rapidly. A wide range of applications are being used in the automotive industry, from vehicle aerodynamics, passenger thermal comfort, to HVAC and component analyses. Each year, new features or improved, more efficient processes are introduced that help our clients. This presentation will look into some of the new features for STAR-CCM+ and how these features are being used productively in industry. It includes an overview of the current gains in turn-around time using coupled solver for aerodynamics,...
Conjugate heat transfer simulations of a bypass valve for the next generation of highest-efficient power plants
Increasing the efficiency for future steam cycle power plants is of significant importance for the reduction of their CO2 emissions. Today’s best steam cycle power plants have a net plant efficiency of 46% while the average efficiency value for such power plants worldwide is still around 30%. Consequently, there exists a great potential for a reduction in CO2 emissions by replacing old power stations with new ones. Yet, a greater potential can be achieved if even higher efficiencies are obtained. In order to push the efficiency of stem power plants significantly over the 50% mark, further...
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...
