Experimental and Computational Studies of Heat Transfer in Complex Internal Flows.
Abstract
The details of five distinct pieces of research are set forth in this report. These research problems are interrelated in that they deal with various aspects of complex duct flows. Four of the research problems are experimental in nature. The first deals with the influence of plenum chamber geometry on the heat transfer and fluid flow characteristics in tubes situated downstream of the plenum. In the second experimental problem, the mixing of fluids of different temperatures in a tee is studied. The third experiment is focused on the fluid flow (without heat transfer) in arrays of longitudinal fins, while the last of the experiments treats a nonuniformly heated noncircular duct. The objective of the analytical work was to develop a turbulence model for rectangular passages, and one of the test cases for the model was to predict the friction factors that had been measured for the longitudinal fin arrays.
