Field of Research

Experimental and Numerical Investigation of ALTP-Sensors in High-Enthalpy Flows

Atomic Layer Thermopiles (short: ALTP) are a new type of heat-flux sensor for the study of heat- transfer problems in fluid mechanics and thermodynamics. By this sensor, the transverse Seebeck-effect through an anisotropic thin YBCO film (centered in sensor in figure 1) is used to determine the heat-flux through the film. Unique characteristics of ALTPs are:

Heat flux measurements over several magnitudes (from the mW/cm² range up to several kW/cm²)
Temporal resolution, which covers a frequency range up to 1 MHz

My field on interest is the application of ALTP sensors in high-enthalpy flow environments like hypersonic flows and combustion processes. Currently, I study the ALTPs behaviour in hypersonic laminar-turbulent transition on a cone (see figure 2). Here, the focus lies on the numerical simulation and experimental measurement of hypersonic instabilities within the boundary layer (see figure 3) causing the transition to turbulent boundary layer flow. The amplified frequencies are in the range of several hundred kHz. Due to their fast response and high temporal resolution, ALTPs are very well suited for the measurement of such flow instabilities.
