Automotive Powertrain Analysis
Jaguar Cars Ltd
Jaguar Cars Ltd presented three case studies, highlighting the CFD processes
adopted by Jaguar to support their powertrain operations. The first study
is the FLUENT/UNS simulation of the Jaguar AJV8 precision cooling system.
Initial CFD simulations provided boundary conditions for an FEA model
to predict metal temperatures, thermal stresses, and distortion within
the engine. From this work, a good understanding of the system was achieved
and local coolant velocity targets were derived. Subsequent design iterations
are now done using FLUENT/UNS and assessed based on coolant flow alone.
The use of CFD in Jaguar's design activity has expanded rapidly,
along with the number of powertrain staff using FLUENT.
The second study (shown below) concentrated on the AJV8 water pump.
Multiple reference frames were used to investigate potential improvements
to the pump housing and impeller. The third and final study looked at
the inlet port and chamber design of the AJV8. CFD was used to provide
detailed flow field information, complementing global data obtained using
a test rig, and giving further insight into the evolution of the flow
and the source of flow losses.
