Titel
Homogenization strategies for fiber curtains and bundles in air flows
Abstract
In non-woven manufacturing thousands of slender fibers are swirled by air flows before they lay down to form a web. The fiber-fluid interactions have a crucial influence on the quality of the final product. For the purpose of an efficient and fast computation of the multi-scale, two-way coupled interaction problem, we investigate classical homogenization strategies and a new continuum approach for very long fibers suspended in a fluid flow. We compare the results with Direct Numerical Simulation (DNS) and Immersed Boundary Methods for academic examples.
