Abstract
The overall objective of this proposal is to develop a standalone module for efficient LES of incompressible and transonic flow of rotorcraft wake on a distributed network of multicore CPUs and GPUs. The module will be based on a Lagrangian Vortex Particle Method (LVPM) and will include the capability to interface with other CFD codes, using Python or a similarly versatile language. The interface will be developed with "code agnosticism" in mind, allowing it to exchange requisite input/output variables and parameters between the LVPM and arbitrary external CFD solvers. A compressibility model will be introduced to LVPM to allow for a more natural interface with compressible CFD codes. Novel software and hardware technologies will be implemented to substantially accelerate the simulation turn around times. Phase I will involve implementation of LES on a cluster of GPUs, interfacing LVPM with a well-established CFD code, and demonstrating proof of concept using a number of test problems.
