Comparison of RANS-based jet noise models and assessment of a ray tracing method

Abstract Four models to predict jet mixing noise available in the literature are reviewed and compared. Two models are derived from the Lighthill Acoustic Analogy (LAA) and the other two use the Linearized Euler Equations (LEE) with added source terms. All models use input from a computational solution of the Reynolds-Averaged Navier–Stokes (RANS) equations and empirical functions to model turbulent correlations. The models are concerned with the sources of sound related to small turbulent structures. Results for an observer at 90 $$^{\circ }$$ to the jet axis are presented, where effects of sound-flow interaction are negligible and the small structures are considered to act as the dominant source. A range of subsonic jets issued from different nozzle geometries with different exit velocities and temperatures is considered. In addition, a ray tracing method to compute the effects of sound refraction is reviewed. The comparison of the numerical predictions with experimental data shows that using the LAA with an improved description of turbulence statistics results in a model as accurate as the ones based on the LEE that relies on less empirical coefficients and has a simpler mathematical derivation. The results corroborate the use of RANS along with LAA to model jet mixing noise.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
