Numerical Simulation of Multi-Dimensional Acoustic Propagation in Air Including Effects of Molecular Relaxation
Friday, February 10, 2006 4:00 p.m. Mark Wochner Applied Research Laboratories, The University of Texas at Austin http://www.arlut.utexas.edu A computational acoustic propagation model based upon the Navier-Stokes equations was developed that is able to simulate the effects of absorption and dispersion due to shear viscosity, bulk viscosity, thermal conductivity, and molecular relaxation of diatomic nitrogen…
