%0 Book %T Flow structures and heat transfer on dimpled surfaces %A Turnow, Johann %D 2011 %G English %F 72709257X %O vorgelegt von Johann Turnow %O Rostock, Univ., Fak. für Maschinenbau und Schiffstechnik, Diss., 2012 %X The investigations of unsteady effects and its direct impact on heat transfer enhancement is the main subject of the work. Vortex structures and heat transfer mechanism in a turbulent flow over a single dimple and a staggered dimple array in a narrow channel have been investigated using Large Eddy Simulation (LES), Reynolds-averaged Navier-Stokes (RANS) simulation, POD method, Laser Doppler Velocimetry (LDV), time resolved pressure measurements and dye visualizations. Further a multi-objective design optimization has been performed for further improvement of the heat exchanger performance. %L UF 4300 %9 theses %9 Text %9 Hochschulschrift %U http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2012-0074-8 %U http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2012-0074-8&pdf %U http://nbn-resolving.de/urn:nbn:de:gbv:28-diss2012-0074-8
