The complex interaction between three-dimensional passage flow structure and endwall convective heat transfer in a square cross section, 90° turbulent duct flow has been experimentally investigated. Fine details of the momentum and heat transport process in a laboratory model that simulated a high Reynolds number three-dimensional passage flow are presented. The complete Reynolds stress tensor was measured using a triple sensor hot wire. The turbulent normal and shear stresses, turbulent kinetic energy, and production of turbulent kinetic energy are presented. A steady state heat flux measurement technique and liquid crystal thermography were used to determine the character of the endwall heat transfer in the form of a high resolution heat transfer map.
