Simulation of a vane cell oil pump
For some time now, regulated vane cell oil pumps have been used when necessary in engines for Mercedes-Benz passenger cars. This new technology requires adjustment to the established simulation methods in order to achieve optimum efficiency and operational reliability. The kinematics of vane cell pumps is based on a combination of translatory and rotary motion. The challenge for simulations lies in the substantial change in chamber volume in conjunction with a virtually incompressible fluid and complex inflow and outflow geometries. A basic requirement for these simulations is the calculation...
The InDesA Virtual Test Bench
As InDesA has specialized on the simulation and analysis of complex flow and heat transfer systems with STAR-CCM+ such as the under-hood hot soak simulation for passenger cars , it has became evident that great care had to be taken to implement auxiliary components such as heat exchangers, cooling fans and coolant pumps in order to accurately predict the overall system behavior. InDesA has therefore started to build up its Virtual Test Facility Center to investigate hydraulic and heat transfer performance of automotive auxiliary components. In the scope of this investigation auxiliary devices...
Customizing STAR-CCM+ for seamless integration to PLM
The cutting edge of simulation in industry is already embracing PLM integration techniques. This presentation will highlight some of the features of STAR-CCM+ that are available to get started. Examples will be provided for how this process can become seamlessly integrated with additional customized tools.
The results of a numerical study are presented: An underground vehicle facility was constructed to analyze the partial transverse ventilation system in the case of fire. A special section of tunnel which was separated into two ventilation shafts was considered. This section was located between two axial jet fans. In the simulations, these two jet fans were not modeled directly but the effect of discharge velocity was implemented as a boundary condition. The main objective of the study was to investigate effects of fire barriers on different transverse extraction strategies. All the...
