The use of combined methods of heat transfer intensification, i.e. a combination of regulating elements with appropriately shaped heat exchange areas seems to be highly effective. The study focused on the analysis of local values of heat transfer coefficients in indicated cuts, in distances expressed as a ratio x/s for 0; 0.33; 0.66 and 1. As can be seen from our findings, in given conditions the regulating elements can increase the values of local heat transfer coefficients along shaped heat exchange surfaces. An optical method of holographic interferometry was used for the experimental research into temperature fields in the vicinity of heat exchange surfaces. The obtained values correspond very well with those of local heat transfer coefficients αx, recorded in a CFD simulation.}, type={Artykuły / Articles}, title={The Effect of Regulating Elements on Convective Heat Transfer along Shaped Heat Exchange Surfaces}, URL={http://journals.pan.pl/Content/84812/PDF/01-paper-Cernecky.pdf}, doi={10.2478/cpe-2013-0002}, keywords={heat transfer, convection, holographic interferometry}, }
