Two discrete models approximating the temperature distributions within imperfectly thermally insulated channels subject to diffusion and axial flow were developed and compared. One model neglects the effects of temperature on diffusion in the interest of model simplicity, while the other explicitly accounts for these effects. Neglecting temperature effects on diffusion allows for the decoupling of the mass transfer and heat transfer problems, allowing a single mass transfer solution to be used to develop multiple heat transfer solutions without re-solving the mass transfer model. In this work, an analytical solution to the mass transfer problem is adapted from existing literature for use in this de-coupled case. The second model accounts for the coupling effects by solving the heat and mass problem concurrently, improving the fidelity of the model in exchange for greater computational demand. Both models require the flow properties at the channel inlet as inputs. When applied in the context of a simulation using parameters representative of a typical small-scale industrial spiral-wound reverse osmosis module, the two models are effectively identical in their temperature distribution predictions despite differing slightly in their permeate flux predictions. The models both predicted temperature increases on the order of 0.1 K along the length of the module, depending on the parameters used. Future work will focus on the experimental validation of these two numerical models.","PeriodicalId":446767,"journal":{"name":"Progress in Canadian Mechanical Engineering.

A new processing method is developed for adding wood-fibers to polylactic acid (PLA) polymers to produce wood-fiber reinforced PLA filaments in order to 3D print high-performance composites. Dogbone samples are 3D printed with the produced filaments to evaluate their elastic and fracture properties as well as internal microstructure, with various weight fractions of wood-fiber. The experimental results demonstrate increased stiffness and ultimate strength and reduced density for composites with optimum wood-fiber content, compared to the pure PLA specimens. Furthermore, following the growing interest in lightweight cellular solids, wood-fiber reinforced PLA filaments are used to 3D print cellular materials with optimized microarchitectures. It was demonstrated that using wood-fiber reinforced composites for FDM 3D printing of advanced materials is a promising approach to not only extend the material properties of biopolymers but also to offer a new class of lightweight and sustainable structural materials. The experimental results on as-built 3D printed cells, compared with the results of a detailed computational analysis on as-designed cells, elicit that the designed architected cellular solids made of wood-fiber PLA composites can exhibit a considerably higher stiffness and ultimate strength than the conventional PLA hexagonal honeycombs.","PeriodicalId":446767,"journal":{"name":"Progress in Canadian Mechanical Engineering.
