Structured sheets have addition to increased bending
stiffness considerable potential for lightweight. Unsteady turbulent flows around the plain and hexagonal sheets were
analyzed numerically and experimentally in order to determine the heat transfer intensity between sheet surfaces and surrounding air flows. To obtain experimental results for later validations of numerical results, a measurement facility was designed and constructed. Flow patterns around metal Sheets were measured under various flow conditions e.g. the effects of different temperatures, heating powers and flow velocities on the
heat transfer intensity were studied. Numerically provided results demonstrated a good match between theoretical calculations and experiments. For all investigated patterns, the structured hexagonal sheets achieved significantly higher heat Transfer intensity than the plain sheets.
