There is a Ph.D. position open in the area of physics-based modeling of wildland fires. Multiple interacting 
processes including pyrolysis, combustion, turbulence and radiation make wildland fires complex, yet 
interesting phenomena. Physics-based models utilize advanced computational tools such as various CFD 
techniques to describe the behavior of fires. The student to be recruited to this position will meet the 
following requirements. 

Requirements:
M.S. in Mechanical, Aerospace, or Chemical Engineering with background in CFD 
Demonstrated skills in Matlab, Fortran or C programming 

Preferred but not required:
Background in combustion or turbulence
Experience with parallel computations 

Applicants should send their CV's to Dr. Babak Shotorban at babak.shotorban@uah.edu. 

The subject of the internship deals with modeling and simulation of various
phenomena occurring during demixing process in glasses, such as
nucleation/growth, spinodal decomposition and coalescence. The phase separation
is currently modelled by Navier-Stokes equations coupled to a phase-field model
(Cahn-Hilliard equation). Those equations are simulated by Lattice Boltzmann
methods (LBM).

In this internship, one or several phenomena of two-phase flows (buoyancy and
coalescence of bubbles or Rayleigh-Taylor instability, ...) will be simulated by
using an alternative phase-field model. The work will be performed inside a
numerical code implementing this alternative model, written in c++ and already
validated on several tests (e.g. vortex and Zalesak's slotted disk). After
checking numerical implementation, several simulations of parameters sensitivity
will be performed. Computation times will be compared between GPU and CPU platforms.

Skills required: Fluid Mechanics, or Materials Sciences or Applied Mathematics
or Physics with skills on scientific computing, physical modeling and analytical
calculations.

Master Thesis topic: FEM Numerical modeling of rotating steam turbine blade
using Beam Element Method.

Scope: The rotating cantilever beams are of great interest in many engineering
fields. The rotor blades of power turbine are one of such example. In the
present master thesis research work such rotating beam will be numerically
modeled and their structural behavior during high rotational speed will be
studied using Beam Theory e.g. Euler-Bernoulli beam theory or Timoshenko Beam
theory or more advanced one.  
The long flexible and ultra-thin steam turbine blade have greater
tendency of vibration, therefore, needed to be designed well especially when
they rotate at 3600 rpm. The blades have non –linear shapes e.g. twisted, tapped
and also additional stiffening due to rational centrifugal force. All this will
be address in the numerical model.  There is some work have been done by
previous master student on rotating rectangular rotating beam with low, up to
500 rpm, So the new master student will add further more in the method to
simulate the structural behavior for up to 3500 rpm, with exact shape of turbine
blades, which the calculation more challenging, due higher rpm and the
non-linear shape.
This kind of numerical tool have great application on fast aeroelastic analysis
in power turbine blade 3D cascade, wind turbine or rotor craft structural
behavior analysis. The master student will spend time to read the state of art
and formulate the algorithm to model the 3D isolated blade using Beam theories.
For the numerical implementation either MATLAB or Fortran or C/ C++ or Python
can be used depending upon the choice. 
Required qualification: Masters degree/ Bachelors Student in the field of
Mechanical/ Aerospace/ Computational engineering/ Physics/ Navel Engineering or
Similar. Good understanding of solid mechanics/ structural dynamics, FEM, good
analytical and mathematical skills, good programming skills in any of the above
language will be advantageous. Working knowledge of English language will be
preferred.

Note: This is not a job post. This is a Masters thesis/ Internship research
topic for final year Masters (MSc) students. The applicant of this research
topic has to have an internal supervisor in their home university. The Masters
thesis is Unpaid.

Time duration: 6 months
Nationality: EU or Non EU candidates with valid residence permit.
Date of start: Negotiable
Qualification: Masters Student (MSc)
Place: Institute of Thermodynamics, Czech Academy of Sciences, Prague, Czech
Republic.

Masters Thesis Title: Modeling of unsteady aerodynamic flow over wing using
viscous 3D vortex particle method 

Scope:To calculate the unsteady aerodynamic flow over wind or lifting surface,
boundary element method can be used e.g. the panel method. However, the panel
method alone cannot simulate the flow separation and also doesn’t account for
the viscous effect which is very important in unsteady load calculation.
Therefore, the proposed master thesis will focus on the development of a hybrid
boundary element method which can be fast compared to CFD and can simulate the
viscous effect using the boundary layer theory and the shear layer separation
will be modeled using the 3D vortex particle method.  
This kind of tool has great application in fast load calculation for aeroelastic
analysis in power turbine blade cascade, wind turbine or rotor craft load
estimation. The master student will spend time to read the state of the art and
formulate an algorithm to model the 3D flow field around a wing and an isolated
blade. For the numerical implementation, either MATLAB or FORTRAN or C/ C++ or
Python can be used depending upon the choice. 
Required qualification: Masters degree/ Bachelors Student in the field of
Mechanical/ Aerospace/ Computational engineering/ Physics/ Naval Engineering or
similar. Good understanding of fluid mechanics/ aerodynamics, good analytical
and mathematical skills, good programming skills in any of the above languages
will be advantageous. Working knowledge of English language will be preferred.
