Angebotene Bachelorarbeiten:
01.12.2017Wall-shear stress measurements of a turbulent wavy channel flowInfoblatt herunterladen

The Micro Pillar shear-stress sensor is designed for the measurement of the wall-shear stress distribution at high spatial and temporal resolution. It consists of an array of flexible cylinders flushmounted to the surface, protruding into the viscous sublayer and bending as a result of the fluid forces. The material of the cylinder is PDMS silicone such that the sensor has high elasticity, and the spheres on top of the pillars enable them to be optically detected. In the measurement, the pillars are to be mounted on four different positions of a sinusoidal surface, in order to study the influence of pressure-gradient on the wall-shear stress.

The work of the students:
- Fabrication of the sensors using silicone and casting molds
- (bonus) Construction using CAD software (i.e. Inventor/CATIA) and communicate with workshop
- Assistance during the measurement
- Basic post-processing of measurement data

Requirements:
- Basic understanding of Fluid Dynamics
- Capability in doing practical work
- Thesis written in English
- (bonus) CAD software (Inventor/CATIA)

Beginning:
From now on
