As part of the final project for ME 614 (Computational Fluid Dynamics) at Purdue University taught by Professor Scalo of the Mechanical Engineering department.
Solves the 2D compressible Navier-Stokes equations using finite-difference with a staggered grid arrangement to simulate acoustic waves in a doubly periodic domain. For more details, please refer to the report by clicking here.
The pressure fluctuations of acoustic waves in a doubly periodic domain are shown below.
Below illustrates the expected 2nd-order convergence of the staggered finite-difference scheme is acheived.
The grid arrangement for x-velocity, y-velocity, and passive scalars are shown below, respectfully.
The sparsity pattern for the finite-difference operators for the x-momentum, y-momentum, and energy equations are shown below, respectfully.
