Bicycle Aerodynamics: Fast Paced Research and Innovation Using Cloud HPC

SESSION: HPC Impact Showcase Wednesday

EVENT TYPE: HPC Impact Showcases

TIME: 11:00AM - 11:40AM

SESSION CHAIR: David Halstead

ROOM:Booth 3947

ABSTRACT:
In the ever-accelerating pace of the bicycle industry product development cycle, use of cloud-based high-performance computing (HPC) and macro-based automation has been playing a critical role in pushing the boundaries of Treks engineering R&D. This presentation will highlight the benefits that HPC-based computational fluid dynamics (CFD) has brought to Trek. Examples will be used to showcase the industry-leading design process. Trek has been successfully implementing an HPC-based CFD program, where the production-related simulation solver elapsed time was reduced as much as 90%. In addition to the speed, HPC has enabled the engineers to change the course of design method. More intelligent model choice is now possible with fast DOE and optimization. Additional computation power has also brought high-fidelity simulation using detached eddy simulation (DES) to further enhance the understanding of bicycle aerodynamics. URANS and overset simulations have also been used to uncover aerodynamics insights that may be unique to bicycle testing. The successful integration of the on-demand cloud HPC and local process automation leads to significant increase in productivity, specifically in analysis turnaround time reduction and rapid design iterations. This cost-effective, high-output approach will continue to drive the future of innovation culture at Trek.
