摘要：

In fiber concrete the mechanical properties are partly determined by the orientation and alignment of the fibers. The fiber orientations depend largely on the casting process, formwork form, formwork surface, manual intervention and vibration. It is therefore important to be able to predict fiber orientations by simulating the casting process using computational fluid dynamics. Calibrating the fluid dynamics program is a problem, as the results not only depend on the rheological properties of the fluid-matrix, but also on the initial fiber orientations. In the poster, important aspects of designing benchmark cases for calibration and testing of fluid dynamics simulation for predicting fiber orientations are discussed.
