چکیده

We propose a continuum description for the axial separation of granular materials in a long rotating drum. The model, operating with two local variables, concentration difference and the dynamic angle of repose, describes both initial transient traveling wave dynamics and long-term segregation of the binary mixture. Segregation proceeds through ultraslow logarithmic coarsening. [S0031-9007(99)09348-5]

Vibration Analysis of Rotating Shaft with Loose Disk

In this paper energy method is used to calculate rotor response with loose rotating disk on it. System equation of motion is obtained based on energy method and Lagrange equation. Mathematical modeling of loose disk in a rotor bearing system has resulted in terms similar to unbalance and gyroscopic effect in the system equation of motion. The effect of loose disk axial position and orthotropic ...

مطالعه عددی انتقال حرارت در فضای مابین دو مخروط ناقص هم‌محور

The behavior of the flow between two coaxial conical cylinders with the inner one rotating and the outer one stationary is studied numerically. The angular velocity of the inner cone cylinder was raised step by step from the rest until reaching its final speed. In this work we first present a numerical simulation of the flow characteristics and the heat transfer mechanism of a fluid in the spac...

Numerical Investigation of Rotating-Stall in a Stage of an Axial Compressor with Two Different Approaches

An unsteady two-dimensional finite-volume solver was developed based on Van Leer’s flux splitting algorithm in conjunction with “Monotonic Upstream Scheme for Conservation Laws (MUSCL)” limiters and the two-layer Baldwin-Lomax turbulence model was also implemented. To validate the solver, two test cases were prepared and the computed results had good agreements with reference data. The rotating...

Transition to Centrifugal Particle Motion in Rotating Drums

The dynamics and the transition to the centrifugal regime are studied analytically and numerically for particles in rotating drum. The importance of the particle-wall friction coefficient is demonstrated by studying first the motion of one non-rotating particle where three different regimes are found in the transition to the centrifugal motion. When a few rotating particles are considered, they...
