NING Research is an Equal Opportunity Employer.

The tentative starting date is: January 1, 2022 although an earlier start date is also possible.

The postdoctoral candidate will work with the NUMA model (Nonhydrostatic Unified Model of the 
Atmospheric).  Assuming available funding, the candidate will work on adding new capabilities to this unified 
continuous/discontinuous Galerkin compressible Navier-Stokes solver.  Some of the topics that will be 
considered include:

1. adding r-refinement and p-refinement to NUMA. NUMA already has non-conforming h-refinement.  In 
addition, the candidate may work on modifying the fully 3D refinement strategies to only include the 
horizontal direction (along the surface manifold).

2. NUMA currently uses OCCA to exploit GPUs but will consider other approaches (e.g., OpenACC, OpenMP).

3. NUMA is equipped with  large suite of explicit, implicit-explicit, and fully-implicit time-integrators and 
physics-based preconditioners. We would like to consider other preconditioners (e.g., geometric multgrid).

4.  NUMA can run both global simulations (on the 3D spherical planet) and also in a limited-area configuration 
(e.g., flow in a large 3D box). The candidate will use the limited-area configuration in order to study hurricane 
rapid intensification. We propose to do this test in order to leverage the: 1) time-integrators and 
preconditioners, 2) the adaptive mesh refinement strategies, and 3) moist processes (already in the model 
but not tested in this setup).

The interested candidate is asked to visit the NRC research opportunity at:
http://nrc58.nas.edu/RAPLab10/Opportunity/Opportunity.aspx?
LabCode=62&ROPCD=621002&RONum=B7054

Before submitting a proposal through the NRC portal, the candidate should send a CV with 3 references to 
Prof. Frank Giraldo at fxgirald@nps.edu. Please be sure to indicate your citizenship even though non-U.S. 
citizens are eligible.
Make sure to add in the subject line the text "NRC postdoctoral position at NPS"

The successful candidate will then be invited to submit a proposal to the NRC website (in collaboration with 
the research advisor).  

Salary is $US 67,000 with a $US 3000 annual travel budget.

"In this present chapter, a description of the purpose of using the various 
different liquid spray breakup modeling techniques now available in the 
current CONVERGE code for the purposes of simulating the breakup of 
particles of a liquid nature in the domain can be found."

The Emmy Noether Group for Dispersed Multiphase Flows was established at the 
Chair of Mechanical Process Engineering in January 2021 and is funded by the 
German Research Foundation. One of our objectives is to investigate the 
cultivation of mesenchymal stem cells on suspended microcarriers and deduce 
recommendations for the upscaling to industrial sizes of microcarrier-based 
bioreactors. In this regard, we develop a probabilistic modelling framework for 
describing particle-laden flows that naturally accounts for the small-scale 
interactions between turbulence, metabolic processes and microcarrier dispersion.

Background: Mesenchymal stem cells are not only the progenitors of skeletal 
tissues, but also possess the capacity to orchestrate regenerative and trophic 
processes in other tissues. For this reason, they are sometimes referred to as 
injury drugstores. In regenerative therapies, mesenchymal stem cells are 
extracted from a donor's bone marrow, expanded in culture and, subsequently, 
transplanted into patients for treating diseases as different as asthma, multiple 
sclerosis and diabetes. One challenge associated with the cultivation of 
mesenchymal stem cells is that the cells require a surface to adhere to in order 
to proliferate. In a technology that is currently investigated, the cells are 
seeded on so-called microcarriers (about 200µm-sized beads) and agitated in a 
nutrient medium. The dispersion of microcarriers in a moving nutrient medium is a 
multiphase flow in which fluid mechanical transport modulates the cells' nutrient 
uptake and viability and microcarrier collisions may cause the formation of 
aggregates.

This position: Within the scope of the present project, the large eddy simulation 
(LES) framework will be amended by a probabilistic description of the interaction 
between the chemical medium composition and the microcarrier dispersion. The 
spatial distribution of the microcarriers as well as potential changes in their 
properties are described with the aid of a population balance equation (PBE). An 
important related task is the synthesis of detailed biochemical kinetics for the 
rates of nutrient uptake, metabolite release and cell fission. For the numerical 
solution of the governing equations, a Monte Carlo method will be developed and 
combined with a sliding mesh approach. The joint modelling/solution framework 
will be instrumented to predict the cell yield in a family of bioreactors and 
assess the influence of operating strategies. The Research Assistant is expected 
to complete a PhD based on her/his project work.

Your primary responsibilities:
- Consolidation of biochemical kinetics governing metabolic processes and cell 
  fission
- Integration of the reaction kinetics into an existing framework for 
  heterogeneous surface reactions
- Formulation of a population balance equation for the property distribution of 
  microcarriers
- Development of a probabilistic description for the turbulence-mediated 
  interactions between the medium composition and microcarriers
- Development and implementation of a stochastic numerical solution method (Monte 
  Carlo) and combination with a sliding mesh approach
- Validation of the physical model based on existing experimental measurements
- Comparison of different operating strategies based on cell stress exposure, 
  microcarrier collision rates and cell yield
- Participation in the development of our in-house simulation tools using the 
  programming languages C and Fortran
- Supervision of student projects and theses
- Leading tutorials and organizing plenary exercises
- Cooperation and exchange with our colleagues at the Chair of Mechanical Process 
  Engineering

Your profile:
- MSc degree or equivalent in mechanical engineering, process engineering, 
  physics or applied mathematics
- Proven track record in translating physical problems into computer-solvable 
  tasks using numerical methods
- Strong background in heat and mass transfer and fluid mechanics
- A strong interest in computational fluid dynamics
- First experience in developing, debugging and profiling software
- Coding experience in C/C++, Fortran or Matlab
- First teaching experience, for example, as a student teaching assistant
- Fluent command of written and spoken English; experience in academic writing

be optimized. Mesh file and .cfg file are ready. When we start the 
optimization we get a lot of SU2 related errors and we couldn't resolve them.
what is required of you is to optimize the propeller and get good value if you 
can.
