Given a set of irregularly sampled 3D polygonal curves representing composite fibres within micro-computed tomography volume, new approach based on the Frenet–Serret formulas is proposed to measure point curvature and waviness along polyline even when its oscillations are not coplanar. However, direct computation measures would lead ill-formed results depending variant externalities across acqu...

An experimental study of turbulent open channel water flows was conducted that simulated basic features of the flow of molten salt in the convective liquid flow first-wall (CLiFF) concept, which is a part of the Advanced Power Extraction (APEX) study. Unlike many other studies of open channel flows, the present one concentrates on a supercritical flow regime, in which surface waviness and wave ...

Vehicles for future manned space missions will demand unprecedented increases in power requirements and heat dissipation. Achieving these goals while maintaining acceptable size and weight limits will require replacing present single-phase thermal management components with far more efficient twophase counterparts. This study discusses the development of an experimental facility for the study o...

the idea of combining low weight and good mechanical properties has led to efforts to develop a new light fiber/metal laminate (fml) in the last decade. fmls are hybrid composites consisting of alternating thin layers of metal sheets and fiber-reinforced epoxy prepregs. in this study, the effect of fiber orientation on tensile properties of this material is investigated both analytically and ex...

Abstract: This paper presents the results of experimental determination of fiber bed permeability variation with porosity. Flow measurement experiments were designed to measure fiber mat permeability for fiber beds with various fiber volume fractions. Woven fiberglass, chopped fiberglass, and carbon fiber mats were used as reinforcements. The effects of reinforcement type and porosity on fiber ...
