Statistical sources for broadband shock-associated noise using the Navier-Stokes equations

Statistical sources for broadband shock-associated noise using the Navier-Stokes equations

A decomposition of the Navier-Stokes equations is used to identify the equivalent source term for broadband shock-associated noise (BBSAN). An analytical closed-form model to predict BBSAN is developed using an acoustic analogy based on the Navier-Stokes equations. The field-variables are decomposed...
