Experimental and numerical investigation of photoacoustic resonator for solid samples
Said El-Busaidy, Bernd Baumann, Marcus Wolff +2
The photoacoustic signal in a closed T-cell resonator is generated and measured using laser based photoacoustic spectroscopy. The signal is modelled using the amplitude mode expans…
Photoacoustics Modelling using Amplitude Mode Expansion Method in a Multiscale T-cell Resonator
Said El-Busaidy, Bernd Baumann, Marcus Wolff +1
The photoacoustic (PA) effect consisting of the generation of an acoustic signal based on the absorption of light has already demonstrated its potential for various spectroscopic a…
High-Intensity Discharge Lamp and Duffing Oscillator - Similarities and Differences
Bernd Baumann, Joerg Schwieger, Ulrich Stein +2
The processes inside the arc tube of high-intensity discharge lamps are investigated by finite element simulations. The behavior of the gas mixture inside the arc tube is governed…
Nonlinear Behavior in High-Intensity Discharge Lamps
Bernd Baumann, Jörg Schwieger, Marcus Wolff +2
The light flicker problem of high intensity discharge lamps is studied numerically and experimentally. It is shown that in some respects the systems behaves very similar to the for…
Open Photoacoustic Cell for Blood Sugar Measurement: Numerical Calculation of Frequency Response
Bernd Baumann, Marcus Wolff, Mark Teschner
A new approach for continuous and non-invasive monitoring of the glucose concentration in human epidermis has been suggested recently. This method is based on photoacoustic (PA) an…
Backcoupling of acoustic streaming on the temperature field inside high-intensity discharge lamps
Joerg Schwieger, Bernd Baumann, Marcus Wolff +2
Operating high-intensity discharge lamps in the high frequency range (20-300 kHz) provides energy-saving and cost reduction potentials. However, commercially available lamp drivers…
