Oak Ridge National Laboratory showcases UTRC jet engine combustor studies

EAST HARTFORD, Connecticut - A recent article posted to the Oak Ridge National Laboratory (ORNL) website showcases a project featuring the successful efforts of a UTRC Thermal & Fluid Sciences Department research team to quickly generate high fidelity simulations related to jet engine combustion and propulsion.

The project required the development and assessment of a hybrid programming methodology using graphic programming units (GPUs) and central processing units (CPUs). The assessment was carried out using ORNL's Leadership Computing Facility (OLCF) in Oak Ridge, Tennessee.

The team simulated a geometrically simple but physically complex problem involving turbulent mixing and chemical reaction using the direct numerical simulations approach.

The UTRC team demonstrated that it is possible to run simulations five times faster while using the hybrid GPU-CPU approach compared to the conventional CPU only approach. The team also performed critical cost-benefit analyses pertaining to the performance of reacting large eddy simulation (LES) codes.

UTRC's team was led by Vaidya Sankaran, Principal Engineer. Jerry Lee, Staff Engineer, Combustion Science, Peter Cocks, Staff Engineer, Propulsion Technology, and Marios Soteriou, Department Fellow, were also key contributors to the project.
