Turbulent Flow and Heat Transfer in Passage Around 180 degree Bend - An Experimental and Numerical Study.

Abstract

A review is presented of the first year of research performed in an investigation aimed at developing a calculation scheme for predicting general three-dimensional flows in curved passages of circular and square cross-section. The experimental component deals with the implementation and validation of a laser-Doppler velocimeter and associated instrumentation. The numerical component deals with the development of a technique for reducing numerical diffusion in the calculation scheme. An update is provided of the current status of the research. A tentative schedule of work for years two and three is also given. (Author)
