Featured researches published by D. Hein.


9th International Symposium on Application of Laser Techniques to Fluid Mechanics | 2000

Measuring Water Temperatures by Means of Linear Raman Spectroscopy

J. Karl; M. Ottmann; D. Hein

In many cases it is necessary to measure local water temperatures with high local resolution. The usage of common thermocouples limits the local resolution, affects the temperature field and may cause incorrect readings.


5th ASME/JSME Joint Thermal Engineering Conference | 1999

Effect of spontaneous condensation on condensation heat transfer in the presence of non-condensable gases

J. Karl; D. Hein


12th European Conference on Biomass for Energy | 2002

Performance characteristics of the Biomass Heatpipe Reformer
