The Spinning Cone Column (SCC) is a mechanically assisted gas-liquid contacting device which has been successfully applied to a broad range of distillation processes in the food and beverage industries. SCC technology is now being adopted for a variety of specialised tasks in the chemical and process industries. In this review, the technology is described and its operating principles explained....

Regarding the importance of ring spinning method among spinning systems, great potentials exist for research about on the improvement of the quality and properties of ring spun yarn. This study aims to improve yarn quality by changing the shape and dimensions of spinning triangle through forming a groove in the middle zone of the front darfting roller with a curvature of 5 to 7 mm. For the to...

The dynamics of gas flow through spinning cone columns (SCCs) have been studied through Computational Fluid Dynamics (CFD) simulations, and the liquid flow characteristics on the rotating surfaces have been correlated through dimensional analysis. The CFD simulations have been carried out in the absence of liquid flow. Flow instabilities are predicted above a critical value of the hydraulic Rey...

We designed a specially designed coaxial spinneret in this study. The inner stainless-steel needle was connected to the inner plastic syringe just like the traditional one. The outer stainless-steel needle was replaced by a plastic nozzle, and connected to the outer plastic syringe. The tip of the inner stainless-steel needle was shortened 2 cm from the tip of the outer plastic nozzle. This str...

In a previous paper, pressure drop, flooding and mass-transfer characteristics of a novel pilot-scale distillation column called spinning cone column (SCC) were presented. Here, we present the result of comparison of mass-transfer efficiencies of SCC and structured packing. Comparison of SCC and structured packing mass-transfer characteristics show that the gas and liquid-side height of transfe...

The geodesic motion of pseudo-classical spinning particles in the Euclidean Taub-NUT space is analysed. The generalized Killing equations for spinning space are investigated and the constants of motion are derived in terms of the solutions of these equations. A simple exact solution, corresponding to trajectories lying on a cone, is given. E-mail address: [email protected]

The attitude dynamics and manoeuvre survey in this paper is performed for a mission scenario involving a penetrator-type spacecraft, a semi-rigid axisymmetric prolate spacecraft spinning around its minor axis of inertia, requested to perform a 90° spin axis reorientation manoeuvre. In contrast to most existing spacecraft only one attitude control torque is available, perpendicular to the spin a...

We review the geodesic motion of pseudo-classical spinning particles in curved spaces. Investigating the generalized Killing equations for spinning spaces, we express the constants of motion in terms of KillingYano tensors. The general results are applied to the case of the fourdimensional Euclidean Taub-NUT spinning space. A simple exact solution, corresponding to trajectories lying on a cone,...
