DIVISION OF BUILDING, CONSTRUCTION AND ENGINEERING

Highett, Victoria

The CSIRO Division of Building, Construction and Engineering has extensive fluid dynamic research facilities at its Highett Laboratories.  During the past decade the research of the Advanced Fluid Dynamics Laboratory (AFDL) at the Division has become more industrially focussed.  This trend has increased the need for fundamental research to underpin industrial research.  Three positions are required to undertake fundamental fluid dynamics research related to the mixing of fluids.  The understanding of fluid
 mixing will be enhanced by relating strain, vorticity and turbulence parameters to mixing distribution and rate.

Experimental Fluid Dynamicist
$42K-$57K + Superannuation
Position BCE94/12

The Advanced Fluid Dynamics Laboratory (AFDL) is undertaking strategic research in the area of stirred vessel mixing.  We wish to appoint a scientist to work in the area of experimental fluid dynamics applied to mixing in flows of different rheologies. Your work will be to undertake sophisticated flow measurements by applying advanced flow measuring techniques to gain an understanding of mixing in terms of vorticity, critical point theory, shear strain etc. These data will also be used for validating softw
are.

Initially, your task will be to investigate the coupling between the circumferential instabilities in the swirling flows generated by axial impellers with sloshing instabilities of the bulk flow in a mixing vessel. You will have a PhD in Engineering or equivalent qualification.  You will have extensive experience in experimental fluid dynamics, in both Newtonian and non-Newtonian flows, and in the study of particle transport using optical flow measuring techniques. Experience in solid/liquid flow measureme
nt using nuclear magnetic resonance techniques would be a distinct advantage.  You will be required to work in a team environment and possess highly developed communication skills.

More information:  You are invited to telephone Martin Welsh on (03)252 6000, fax (03) 2526240 or via electronic mail (mcw@mel.dbce.csiro.au) for further information.

Computational Fluid Dynamicist
$42K-$57K + Superannuation
Position BCE94/13

The Division is undertaking strategic research in the area of stirred vessel mixing.  We wish to appoint a scientist to work in the area of Computational Fluid Dynamics applied to mixing in flows of different rheologies. Your work will be to develop sophisticated software for the prediction of these flows.

Initially, your task will be to develop a spectral-element code capable of predicting the unsteady flow conditions that prevail in a mixing vessel and to study the application of chaos theory to mixing.  You will have a PhD in Mathematics or equivalent qualification.  You will have postdoctoral experience in developing and applying spectral/finite element codes to non-Newtonian fluid  flows and the study of particle transport. You will be required to work in a team environment and possess highly developed 
communication skills.

Post Doctoral Fellowship
Experimental Fluid Dynamicist
$37K-$47K + Superannuation
Position BCE94/14

The position involves experimental research on the dynamics of fluids mixing in stirred vessels and in jets.  It will involve measurement of mixing and flow patterns in liquids, liquids with suspended particles and with aeration.  Newtonian and Non-Newtonian fluids will be studied.  The results will be related to computational and theoretical models.  Strategies will be developed for improving mixing and efficiency in stirred vessels.

A PhD in engineering or equivalent is required.  Experience in experimental fluid mechanics, particularly advanced techniques of fluid flow velocimetry such as Laser Doppler, Hot-wire and Particle Image Velocimetry, is essential.  Candidates should have no more than 3 years relevant experience since confirmation of the degree.  The successful candidate will be required to work in a team environment and should possess highly developed communication skills.

The appointment is for a period of three years.

More information:  You are invited to telephone Ian Shepherd on (03)252 6000, fax (03)252 6240 or via electronic mail (ics@mel.dbce.csiro.au) for more information.

Experimental Fluid Dynamicist


Job Description

You will be part of a team participating in the theoretical, numerical and experimental investigation of mixing.  Strategic research is currently being carried out to underpin industrial research into mixing for industry. Some of the techniques being used are particle image velocimetry and nuclear magnetic resonance.

Post-Doctoral Fellowship
Experimental Fluid Dynamicist

Job Description

You will be part of a team participating in theoretical and experimental investigations of the dynamics of fluid mixing processes.  Applications will involve mixing in stirred vessels containing liquid, solid particles and gas bubbles, and mixing of fluid jets discharging into a cross flow and into plenum.  The Fluid Dynamics Group at CSIRO Highett, has been assisting the building, manufacturing, chemical and mineral processing industries with fluid dynamic research for over twenty-five years.  The researc
h is related to pumps, fans, ventilation systems, flow in ducts, mixing and the development of new techniques for flow measurement.

The study of fluid mixing processes is a CSIRO priority area and your job will initially be in two priority investigations.  One relates to improvement of a mineral processing operation which involves mixing of solids in suspension in an aerated liquid, the other relates to mixing of jets which issue into a cross flow.
