Computational Analysis Of Woodwind Instruments Using The Lattice Boltzmann Method, Jack D. Gabriel

Honors Program Theses

Through the use of the lattice Boltzmann method, a series of computational models were created to simulate air flow in woodwind instruments. Start- ing as a two-dimensional code in Matlab running on the CPU, the model went through a series of iterations before becoming a three-dimension code in Fortran that was accelerated through the use of GPU parallel computing. The accuracy and stability of the model are shown by comparison to various published benchmark tests. Thus far, the air flow in organ pipes for a two dimensional model was simulated showing oscillating flow by the labium as expected. This thesis …
