STAR-CCM+ can accurately predict high-speed flow phenomena including the existence of shock waves, shock-boundary-layer interaction, and high aerothermal loads. With STAR-CCM+, vehicle designers are equipped with powerful tools that can account for the extreme structural and thermal loads present in the hypersonic environment. In this webinar, we will demonstrate the use of HEEDS and STAR-CCM+ in investigating subtle variations in Scramjet design to improve performance. Along the way, we’ll highlight how HEEDS is able to optimize design performance over a range of Mach numbers and operating conditions, in contrast to other approaches that can only assess designs for a single working point at a time.
HEEDS can control parametric geometry variables within STAR-CCM+ to evaluate the impact of design changes on performance. This example uses a 2D STAR-CCM+ model that runs quickly. With process automation and intelligent design space exploration techniques, HEEDS can rapidly assess potential designs at multiple design points with no analyst intervention needed. ATA has also previously configured this workflow to have a local instance of HEEDS orchestrate the main simulations on the AWS cloud, which enables even smaller companies without large compute resources to tackle this type of engineering challenge.
Agenda:
1. STAR-CCM+ for Hypersonic applications
2. HEEDS setup and deployment
3. HEEDS/STAR-CCM+ for a 2D Scramjet design
