Fluid sub-systems are a key part of many engineering systems from lubrication and fuel to hydraulics and pipelines. These systems are large, complex and often highly transient, and the flows are typically internal, pressurised flows – e.g. through pipes, valves and motors. They often require both passive and active control.
This talk will introduce 1D Fluid System Simulation (System CFD) and show how it is used to analyse and design internal flow systems in complex fluid engineering. We will compare system techniques with 2D and 3D CFD techniques – showing that they are complementary.
System CFD allows engineers to quickly build models based using catalogues of pre-defined components. System models are used to:
The talk will present a number of case studies to discuss its use in analysis and design of engineering systems with surge; thermal management; hydraulics; rotating machine
Dr. David Hunt is a Senior Computational Physicist and manages Research, Design and Innovation at FloMASTER, a System CFD product in Mentor Graphics’ Mechanical Analysis Division (Siemens Company).
David oversees Research and Design activities to enhance the simulation capability for gas turbine applications.David works on developing capabilities to support Model Based Design and Synthetic Design and Design Optimisation. A key part of this work has been integrating 3D CFD with System CFD tools.
David has worked on novel algorithms to improve numerical stability within fluid simulations that allow robust simulation of components with complex physics and multiple armed components.
