Position:
- Scientific employee / Research Associate / PhD (m/f/d) in the field of
unsteady flow simulation (3D CFD) and local entropy evaluation for loss
quantification in hydraulic fluid machines for a period of 3 years with 39.83
hours per week (TV-L E13)
Description:
- One of the main research areas of the Chair of Hydraulic Fluid Machinery
(HSM) is the development of 3D CFD methods for the numerical simulation of flows
in fluid energy machines and their components. In the doctoral project,
turbulence-scale-resolving/adaptive simulation methods are to be expanded to
include a time-resolved and local evaluation of entropy production and validated
on complex flows, e.g., pump flows. Particular attention is paid to wall
treatment and hybrid turbulence modeling. The doctoral project offers the
opportunity to delve deeply into the development of CFD methods with a focus on
turbulence and loss modeling and is carried out in close cooperation with
industry.
Tasks:
- Development of 3D flow simulation methods (CFD) based on OpenFOAM
- Development of a scale-adaptive simulation method based on the k-ε-V2F
model
- Evaluation of entropy production
- Development of entropy wall functions
- Validation on measurement and DNS data
- Application to flows in rotating systems such as centrifugal
pumps
- High-performance computing (HPC) / application on mainframe
computers
- Writing scientific publications in English
- Support in teaching
- Coordination with the developers of commercial CFD methods
- Close cooperation with the fluid machine industry and other university
institutes
Profile:
- Completed degree in mechanical engineering, computer science, physics,
applied mathematics or a related discipline
- Above-average academic performance, especially in basic subjects such
as (numerical) mathematics, (fluid) mechanics, thermodynamics, heat and mass
transfer
- CFD knowledge, ideally developer and OpenFOAM knowledge
- Experience in teaching is advantageous, e.g., acquired as a student
assistant
- Programming skills, ideally in C++
- Proactivity, ambition, and purposefulness
- Strong communication skills, both spoken and written
- Knowledge of or willingness to learn German
- Enjoying teamwork
Offer:
- Support from and cooperation with competent colleagues
- Team-oriented cooperation in a committed, international, and
appreciative team
- Employment at one of the largest universities in Germany within the
University Alliance Ruhr
- Options for flexible working
- Possibility of obtaining a doctorate (Dr.-Ing.)
