Nov 01, 1994 INTRODUCTION The objective of this paper is the adaptation of some available Control-Volume-based Finite Element Methods (CVFEM) for single-phase flows [1-8] in order to formulate a CVFEM for the solution of two-fluid models [9, 10] of 2-D, planar or axisymmetric, incompressible, dilute gas-solid particle flows in regular- or irregular-shaped

Apr 14, 2016 In this paper, we comprehensively review the relevant literature published from 2005 to 2016, focused on lumber drying and provide a summary of where we feel future research will focus. Drying is a critical part of most wood products manufacturing process, and the methods used and proper control are key to achieving the appropriate production level, quality, and costs. While a combination

As it has been shown, the above analytical micromechanics methods are strictly valid for inclusions (fibres) with isotropic or transversely isotropic properties

Using wood, we demonstrate the unique ability of upscaling the self-shaping mechanism of bilayers on the meter scale to obtain large-scale components with high curvature. The shaping process by drying of large wood bilayers is shown in Fig. 1 (A to D), and an exemplary time-lapse video is shown in movie S1
