- Title(s):
- Determining the inner diameter of a very thin glass tube from the interference pattern of back-scattered laserlight.
- Supervisor(s):
- Mads Peter Soerensen
- Description:
- For wavelengths that are small compared to the diameter, a good method for calculating the interference-pattern, given the diameter, is that of RAY-TRACING. This is a computer-intensive task for which I am writing the program. This program can be used to find the unknown diameter when the interference-pattern is measured. Project originates from D.F.M (Danish institute for Fundamental Metrology), building 307 first floor.

- Propagation of non newtonian film
- Supervisor(s):
- Ole Hassager, Department of Chemical Engineering, DTU
- Description:
-
A non-newtonian fluid flows in a coaxial annulus displacing another fluid.
The displaced fluid will form a film layer along the walls of the annulus
and writing mass and momentum balances for this film layer, partial
differential equations are constructed and analyzed to describe it.
For analyzing these, characteristics are used along with numerical solutions.

- Solution of boundary and eigenvalue problems

- Description:
- Imagine a beam,
which is fixed inside a rigid wheel, which is rotating with constand ang
ular velocity $\omega$. We thus have a centrifugal force acting on th
e beam, and we ask for the force, resp. the angular velocity, when th
e beam begins to bend. (there is no Coriolis-force, because we only loo
k at the static behaviour of the beam.) Modelling this, we get a d
ifferential equation where the angular velocity appears as an eigenvalue. T
his explains the title of the project.

- Modeling of the Cardiovascular System
- Supervisor(s):
- Michael Danielsen (RUC)
- Description:
- To know how the Cardiovascular system, and particular the heart, is behaving under certain condition, it is convinient to make a simple mathematical model of the system, and then do experiments in here. This is just the case in this project. We only consider the left part of the heart, and from our nowledge about physiology we construct an electrical circuit modeling the systm. We are now able to do experiments, such as modeling a heartattack or make the model make a work, for example ride a bike.

- Description:
- The project is made in cooperation with Skaerbaekvaerket. In conventional powerplants, Deionated water is submitted continously, to keep the water/steam circuit as clean as possible. To deionate this water, ion-exchangers is used. This ion-exchangers are in the form of small spheres. The ion-exchangers has been found to foul the water by breaking down its molecule structure piecewise. Also rests from the production of the ion-exchange molecule will diffuse from the ion exchange spheres. The goal of the project is to model the diffusion and reaction of the molecule-parts. This is done by a partial differential equation The partial differential equation is then solved numerically, to find the speed of the breakdow of the ion-exchanger.
