摘要

An approach to measure and model turbulent flows in complex configurations is presented. It is based on the synergistic use of two novel techniques: the experiments are based on magnetic resonance velocimetry, which allows the collection of a large three-dimensional volume of three-component velocity measurements in a short period of time. The numerical predictions are based on the immersed boundary technique that enables simulations to be carried out on Cartesian grids even for realistic, industrial configurations. Computer models of realistic geometries are used without modification in the simulations, and they are accurately reproduced for the experiments using rapid prototyping manufacturing. These two techniques enable analysis of flow systems in great detail by quickly providing a wealth of experimental and numerical data. Moreover, direct comparison between these datasets gives indications of the uncertainties in the data from both methods. Results are presented for the flow in a pipe and in a rib-roughened serpentine. In addition, preliminary measurements and simulations of the flow around a coral reef are included.
