TL;DR: Results obtained from the computer modelling exercise have demonstrated that CFD model is the best method of modelling the cyclones collection efficiency.
Abstract: This work presents a Computational Fluid Dynamics calculation to predict and to evaluate the effects of temperature, operating pressure and inlet velocity on the collection efficiency of gas cyclones. The numerical solutions were carried out using spreadsheet and commercial CFD code FLUENT 6.0. This paper also reviews four empirical models for the prediction of cyclone collection efficiency, namely Lapple [1], Koch and Licht [2], Li and Wang [3], and Iozia and Leith [4]. All the predictions proved to be satisfactory when compared with the presented experimental data. The CFD simulations predict the cyclone cut-off size for all operating conditions with a deviation of 3.7% from the experimental data. Specifically, results obtained from the computer modelling exercise have demonstrated that CFD model is the best method of modelling the cyclones collection efficiency.

TL;DR: In this article, the authors deal with the modeling of the mechanical behavior of masonry elements regarded as heterogeneous systems, made of mortar and bricks joined by means of interfaces, and a numerical procedure, based on the backward Euler timeintegration scheme, is introduced; the time step is solved adopting a displacement driven predictor-corrector algorithm.
Abstract: The present paper deals with the modeling of the mechanical behavior of masonry elements regarded as heterogeneous systems, made of mortar and bricks joined by means of interfaces. The adopted computational strategy consists of modeling the brick units, the mortar joints and the interfaces responsible for the mortar-brick decohesion mechanisms; to this end, a special interface model combining damage and friction is adopted. A numerical procedure, based on the backward Euler time-integration scheme, is introduced; the time step is solved adopting a displacement driven predictor-corrector algorithm. Some numerical applications are performed in order to assess the ability of the proposed model and algorithm in reproducing the nonlinear response of masonry elements. Finally, unreinforced and FRP-reinforced masonry arches, for which experimental results are available, are modeled and the mechanical response is investigated. The results obtained by the numerical model are put in comparison with the experimental...

TL;DR: In this paper, the authors proposed a rapid convergent differential quadrature method (DQM) for calculating the numerical solutions of nonlinear two-dimensional Burgers' equations with appropriate initial and boundary conditions.
Abstract: In this paper we propose a rapid convergent differential quadrature method (DQM) for calculating the numerical solutions of nonlinear two-dimensional Burgers' equations with appropriate initial and boundary conditions. The two dimensional Burgers' equations arise in various kinds of phenomena such as a mathematical model of turbulence and the approximate theory of flow through a shock wave traveling in a viscous fluid. To the best of the authors' knowledge, this is the first attempt that the system has been solved up to big time level t = 15 and big Reynolds number R = 1200. We also found that Chebyshev-Gauss-Lobatto grid points give excellent results in comparison to other grid points such as uniform grid points. Two test problems considered by different researchers have been studied to demonstrate the accuracy and utility of the present method. Results obtained by the method have been compared with the exact solutions and with those given by researchers for each problem. Solutions obtained by DQM are fo...

TL;DR: The Partially Averaged Navier-Stokes (PANS) as discussed by the authors is a family of closure models parameterized by different ratios of resolved-to-modeled kinetic energy and dissipation.
Abstract: Flow past a backward-facing step is computed using three different turbulence modeling approaches; Detached Eddy Simulation (DES), Unsteady Reynolds Averaged Navier-Stokes (URANS), and the newly developed Partially Averaged Navier-Stokes (PANS) [1, 2] method. PANS is a family of closure models parameterized by different ratios of resolved-to-modeled kinetic energy and dissipation. The corresponding resolution control parameters are f k (the ratio of unresolved to total kinetic energy) and f ϵ (the ratio of unresolved-to-total dissipation). The main objectives of this study are: (i) to investigate the merits of PANS relative to the other two methods by comparing against existing experimental data; and (ii) to examine the effect of the PANS parameter f ϵ on the computed flow field. In addition, we study the sensitivity of PANS results to grid-size and the level of unsteadiness in the inflow. Overall, the results clearly demonstrate the suitability of PANS for computing unsteady turbulent flows at a reasonab...
