Information about the project

The Division of Fluid Dynamics offers a two-year post-doc position (scholarship). The post-doc will work in the IMAGE project (Innovative Methodologies and technologies for reducing Aircraft noise Generation and Emission). IMAGE is an EU-China project, with 12 EU partners and 9 Chinese partners. The project starts 1 April 2015 and has a duration of three years. The object of the project is to investigate experimentally and numerically innovative airframe and engine noise-reduction technologies. Chalmers is the coordinator of IMAGE.

The post-doc will carry out turbulence-resolving simulations using hybrid LES-RANS modelling approaches for flows around tandem cylinders and a wing. The noise generation will be studied in connection to resolved local turbulent flow properties. Analysis of noise-generation mechanisms in terms of, for example, space and temporal correlations of flow and pressure fluctuations will be conducted in relation to effective noise control using turbulence screens and plasma actuators.

For the CAA analysis, a two-step hybrid method will be used, where turbulence-resolving simulations are first conducted in order to obtain noise sources which are then used in acoustic analogies of different types, e.g., the Curle, the Kirchhoff and the FH-W method.

The in-house solver G3D::Flow (http://tfdsl009.tfd.chalmers.se/g3dflow/) will be used for the LES/DES simulations. G3D::Flow is a finite volume code, written in C++ and uses the PETSc library.

Major responsibilities

Your major responsibility as postdoc is to perform your own research in a research group. Another important aspect involves collaboration within academia and with society at large. The position is meritorious for future research duties within academia as well as industry/the public sector.

Position summary

The selected post-doc will get a two-year scholarship. Hence the applicant must not have lived in Sweden for the past three years. Scholarship holders who are in receipt of scholarships to finance their individual education/research while at Chalmers are not regarded as staff and are not eligible for benefits available to staff.

The position is limited to a maximum of two years (1+1).

Qualifications

To qualify for the position of postdoc, you must have a doctoral degree in Mechanics Engineering, Physics or equivalent; the degree should generally not be older than two years. You are expected to demonstrate good potential within research and education.

The position requires sound verbal and written communication skills in English. Chalmers offers Swedish courses.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.

Application deadline: 1 May 2016
