The analytical results indicate that pistons have less influence on churning losses than the rotating cylinder block beyond the critical ...

Abstract. Components such as turbine shafts and discs while rotating at high speeds are subjected to large centrifugal forces, which in turn, produce large stresses that are distributed symmetrically about their axes of rotation. The stress analysis of these components is useful in their safe design so as to prevent their failure.

We explore the steady-state rotational motion of a cylinder on a flat horizontal surface from a pedagogical perspective. We show that the cylinder's inclination angle depends on its rotational velocity in a surprisingly subtle manner, including both stable and unstable solutions as well as a forbidden region with no (real) solutions.

When liquids or solid materials rotate, they impart centrifugal and/or shear forces. This Review surveys rotary devices and systems in which such forces control small-scale flows,...

The flow pattern around the spinning cylinder is also altered as the strength of the circulation increases. In Fig. 5.25 when Γ = 0 the flow pattern is that associated with the previous non-spinning case with front and rear stagnation points S 1 and S 2, respectively, occurring on the horizontal axis.As Γ is increased positively a small amount the …

The cylinder or circular disk is placed in the magnetic field − H (0, 0, Hz) and rotated at a constant angular velocity about the z-axis ω under thermal loads. Here, the hollow cylinder and circular disk are composed of isotropic materials with material properties changing as a power function along the radius direction.

Uniform mixing is highly essential in the food manufacturing, pharmaceutical, chemical, and cement industries. However, based on the various process requirements, these industries use different mixers to achieve their commercial outputs. Most of these industries rely on sample-based verification of the mixing index, which may not produce accurate results. …

To quantify the degree of homogeneity of divided solid materials in a rotating cylinder, the analyzes were performed using both the grey-level co-occurrence matrix (GLCM) textural method (Haralick et al., 1973) and grey level thresholding traditionally used in image processing. The GLCM method quantifies image texture by …

The rotation of a fast moving disc or cylindrical member can set up axial, circumferential and radial stresses. For instance, in the turbine section of an aircraft gas turbine engine, the rotor disc frequently turns at speeds in the region of 10000 r.p.m. This generates large amounts of stresses and strains on the material of the rotor disc.

The transverse flow of granular materials in rotating cylinders is described. The Eulerian formulation is used to describe particle dynamics. Frictional forces between solid particles are taken into account. Particles at the bed surface always re-enter the active layer after a slight jump. A new region is added to the conventional configuration ...

These comprise a horizontal rotating cylinder with a number of longitudinal shelves or lifting flights inside it (Figure 14).The smallest driers of this type have cylinders about 2 m long, 0.5 m dia., and the largest 21 m long, and 2.5 m dia.They are used for drying material that has to be turned or tumbled in the hot gas stream to ensure uniformity of drying.

These materials which possess gradual change in their material properties are known as Functionally Gradient Materials (FGM).
