Axial compressor — Axial compressors are rotating, aerofoil based compressors in which the working fluid principally flows parallel to the axis of rotation. This is in contrast with centrifugal, axi centrifugal and mixed flow compressors where the air may enter… … Wikipedia
axial-flow compressor — A compressor used in gas turbine engines in which the flow of air is maintained parallel to the compressor shaft. An axial flow compressor is made up of several stages of alternate rotors and stators. The number of stages of compression… … Aviation dictionary
Poisson's ratio — ( ν ), named after Simeon Poisson, is the ratio of the relative contraction strain, or transverse strain (normal to the applied load), divided by the relative extension strain, or axial strain (in the direction of the applied load).When a sample… … Wikipedia
Bypass ratio — The term bypass ratio (BPR) relates to the design of turbofan engines, commonly used in aviation. It is defined as the ratio between the mass flow rate of air drawn in by the fan but bypassing the engine core to the mass flow rate passing through … Wikipedia
Perrin friction factors — In hydrodynamics, the Perrin friction factors are multiplicative adjustments to the translational and rotational friction of a rigid spheroid, relative to the corresponding frictions in spheres of the same volume. These friction factors were… … Wikipedia
Crystal structure — In mineralogy and crystallography, crystal structure is a unique arrangement of atoms or molecules in a crystalline liquid or solid. A crystal structure is composed of a pattern, a set of atoms arranged in a particular way, and a lattice… … Wikipedia
Nanopolymers — The word nano is derived from the Greek word for “dwarf”. It is the prefix for units of 10 9. In a nutshell, nanoscience is the study of the extremely tiny. Nanoscience is concerned with the study of the unique properties of matter at its nano… … Wikipedia
Polymer nanocomposite — Polymer nanoscience is the study and application of nanoscience to polymer nanoparticle matrices, where nanoparticles are those with at least one dimension of less than 100 nm. Contents 1 Nanopolymers 2 Bio hybrid polymer nanofibers 2.1 Bio… … Wikipedia
Nanocellulose — or microfibrillated cellulose (MFC), is a material composed of nanosized cellulose fibrils with a high aspect ratio (length to width ratio). Typical dimensions are 5–20 nanometers width and length up to 2000 nanometers. It is pseudo plastic.… … Wikipedia
