Title: | Local Heat Transfer Coefficients Measured with Temperature Oscillation IR Thermography | Authors: | Freund, Sebastian | Language: | eng | Keywords: | Plate Heat Exchanger;Vortex Generator;Spray Cooling | Subject (DDC): | 620 Ingenieurwissenschaften | Issue Date: | 2008 | Publisher: | Universitätsbibliothek der HSU/UniBwH | Document Type: | Thesis | Publisher Place: | Hamburg | Abstract: | A new method to visualize local heat transfer coefficients on heat exchanger surfaces is presented and experimental measurement results on pipe flow, vortex generators, impinging jets, a spray cooling system and a plate heat exchanger are shown. The method relies on IR thermography to measure the heat transferring wall’s temperature response to an oscillating heat flux and a numerical wall model for the calculation of the heat transfer coefficients. This study of local heat transfer coefficients is completed with a comparison of CFD results to the measured data. |
