Özet

The flow field of smooth surfaces and surfaces with V-shaped ribs (V-SR) was studied experimentally with a Laser-Doppler Anemometry (LDA) system. In addition, heat transfer characteristics were experimentally investigated. Heat transfer results from these surfaces under impingement of a circular jet array (5 x 3) using an infrared thermal imaging technique are presented.
