Abstract

In this thesis, the numerical code for predicting the far-field sound radiated from a localized sound source is developed based on Lighthill's acoustic analogy theory. The acoustic analogy equation allows calculating the sound intensity in terms of the integral over the volume with distributed Lighthill tensor of unsteady flow fluctuations. A FORTRAN code is written to perform the integration using Simpson's numeric technique. The procedure for validating the code against the test case for the sound source in the form of a Gaussian pulse is examined. Future application of the code to predict acoustic radiation from turbulent jets is briefly discussed.
