In this paper the numerical simulation of flow field in the new design dynamic cyclone separator is investigated. The effects of different geometrical parameters such as impeller diameter, number of vanes, length and the location of impeller is investigated. The Reynolds averaged Navier–Stokes equations with Reynolds stress turbulence model (RSM) were solved. The Eulerian-Lagrangian computation...

A transmission line model for capacitors is proposed and developed. The model relates electrical parameters to geometrical parameters, leading to simple design rules for power applications. In contrast, design rules based on lumped RLC models are shown to lead to design errors. Experimental results match a simulation based on the distributed model whereas a lumped model gives erroneous predicti...

In this paper, following a two-stage methodology, the differential quadrature element (DQE) model of a three-story frame structure is updated for the vibration analysis. In the first stage, the mass and stiffness matrices are updated using the experimental natural frequencies. Then, having the updated mass and stiffness matrices, the structural damping matrix is updated to minimize the error be...

This paper suggests defining three criteria to differentiate design and non-design, using the concept of effect in a phenomenological perspective. The central concept of this article is the concept of “effect of design,” defined as a three-dimensional result that occurs through usage and turns it into an “experience-to-live.” The three dimensions of the effect of design are the “ontophanic effe...

This study considers a modeling methodology for the design of a computer based problem-solving environment (named L.E.C.G.O: Learning Environment for programming and C using Geometrical Objects) for the learning of computer programming and the programming language C by beginners. For this design, constructivist and social learning theories were taken into account. The general design has taken i...

Two-dimensional (2D) materials provide a platform for strong light-matter interactions, creating wide-ranging design opportunities via new-material discoveries and new methods for geometrical structuring. We derive general upper bounds to the strength of such light-matter interactions, given only the optical conductivity of the material, including spatial nonlocality, and otherwise independent ...

The Solar Photonic Optoelectronic Transformer (SPOT) is one of the components of the SolarBrane, a Building Integrated Photovoltaic (BIPV) system developed by SolarEmpower Ltd. The SPOT employs 2-D linear dielectric totally internally reflecting concentrator (DTIRC) to increase the collection efficiency of the sun’s rays and reduce the amount of photovoltaic (PV) material used. In this paper, a...
