Job Record #15635
TitleCFD of Chemical Biological Radiological Nuclear (CBRN) canister
CategoryPhD Studentship
EmployerNewcastle University
LocationUnited Kingdom, Tyne and Wear, Newcastle Upon Tyne
InternationalNo, only national applications will be considered
Closure DateSaturday, March 30, 2019
The project will utilise advancements of high-performance computing to carry 
out unsteady Reynolds-Averaged Navier-Stokes (uRANS) and Large Eddy 
Simulations (LES) of airflow through CBRN filters in breath responsive 
respirators. The proposed project will particularly focus on: (i) uRANS and 
LES calculations to optimise the shape factors in the presence of adsorption 
modelling; (ii) adsorption modelling with parametric analysis (activated 
carbon particle size, sensitivity to adsorption models, incorporation of 
chemistry); (iii) identification of localised blocking and break away; (iv) 
effects of canister geometry (particularly form fitting geometries) on 
residence time distribution and adsorption within the filter bed at 
different phases during different breathing cycles; (v) identification of 
the correlation between the residence time distribution and adsorption 
characteristics and (vi) effects of particulate contamination of the filter.

The physical insights extracted from simulation data will be utilised to 
optimise the performance of CBRN filter canisters in terms of pressure drop, 
residence time distribution and breakaway for different types/stages of 
breathing cycle of the wearer of the respirator.

Applicants should possess a good honours degree (1st Class or 2:1 minimum) 
in any of the following disciplines:
Aerospace/Mechanical/Chemical Engineering, Physics, Applied Mathematics or 
any related field.

The successful candidate will work in a research group with cutting-edge 
expertise in Computational Fluid Dynamics (CFD), which will support the 
proposed research by providing a conducive environment. Good analytical, 
mathematical, project management and communication skills are required. It 
will be advantageous to have good knowledge of any of following areas: 

Computational Fluid Dynamics, Heat and Mass transfer, and Thermodynamics. 
Experience and interests in Chemical Engineering/Chemistry will be helpful 
but not essential.

The award is available to UK/EU applicants only. Depending on how you meet 
the EPSRC’s eligibility criteria, you may be entitled to a full or a partial 

Value: Full UK/EU fees (eligibility criteria applies to EU students) and 
annual living allowance of at least £18,000 (standard 2018/19 UKRI rate 
industrial top up)
