Description:
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.
