TitleUnderstanding meso-scale structures in dilute gas-particle flow
CategoryPhD Studentship
EmployerCurtin University
LocationAustralia, Western Australia, Perth
InternationalYes, international applications are welcome
Closure DateMonday, September 15, 2014
Description:
Gas-particle flows are central to many industrial processes such as fluid 
catalytic cracking, coal combustion, pyrolysis, chemical looping combustion etc. 
In these processes, the gas-particle flows exhibits heterogeneity at multiple 
scales. At the particle scale, the flow exhibits formation of particle 
aggregates, so called “meso-scale structures” or “clusters”. These clusters are 
not only responsible for the gas-solid flow structures inside the equipment but 
also dictate heat, mass, momentum and species transports. Current knowledge on 
the clusters is limited, and it is extremely critical to characterize (such as 
shape, size and fractions) of the clusters at various flow conditions. And then, 
the cluster characteristics at different flow conditions can be further used to 
capture them in the CFD simulations.
Focusing on the objective to understand the clusters and their impact at various 
flow conditions, the proposed PhD project will conduct direct numerical 
simulations (DNS) of gas-particle flow using the lattice-Boltzmann (LB) and 
discrete element methods (DEM). Following tasks will be completed, (1) 
development of LBM-DEM algorithm, (2) implementation of the LBM-DEM algorithm in 
a computer code using C-programing and openmpi, (3) carryout extensive 
simulations.
Key contributions of this project will be (i) high resolution cluster-scale 
numerical observations, (ii) effects of flow conditions on the cluster 
properties, (iii) resultant gas-solid drag that accurately account for the 
clusters.
For this project, we are seeking highly motivated chemical/mechanical 
engineering graduates with skills in computer programming and computational 
fluid dynamics. The candidate must have an excellent academic record and possess 
reasonable expertise in computer programming languages such as FORTRAN, C, C++. 
The candidate is also required to be familiar with multiphase flow modelling 
techniques such as Eulerian model, Langrangian model, Lattice Boltzmann method. 
Experience in parallel programing and HPC will be added bonus.
For a qualified candidate, the PhD program will be commenced immediately with 
the scholarship of approximately AUD 25000 per year (tax-free). The program will 
be for the total duration of 3 years.
Inquiries and applications should be sent by email to Dr. Milinkumar Shah 
(milinkumar.shah@curtin.edu.au). Applications should include a detailed CV, a 
cover letter with a short statement of research interests and motivation, two 
names of potential referees, complete list of publications, and a page proposal 
on the subject. Applications should be received before 15th September, 2014 for 
full consideration. Later applications will also be accepted until the suitable 
candidate is identified.
