  Abstract

  Biogas production has the potential to provide three benefits for green energy, waste management, and bio-fertilizers. The process involves converting organic waste materials, such as agricultural waste and food scraps, into methane-rich biogas through anaerobic digestion. This biogas can then be used to generate electricity and heat, reducing the reliance on fossil fuels. Additionally, the waste materials are broken down, reducing the amount of waste in landfills, and the process produces nutrient-rich fertilizer for crops. In summary, biogas production can play a significant role in creating a sustainable future. In recent decades, membrane materials have been used and improved to become a proven solution for covering the roof of anaerobic digesters. Coated textiles, with advanced technical properties such as good gas barrier properties, flexibility, and durability, are ideal for this application. The aim of this paper is to provide the reader with a clear understanding of biogas production and the focus on the impact of some plasticizers which can be used for the development of a gas membrane in anaerobic digesters.

  Abstract

  This paper describes a recently developed numerical technique to simulate high-speed flows on complex 3D inflatable structures using tetrahedral volume grids. In detail, the proposed methodology is based on the front-tracking approach, as it involves the coupling between a shock-fitting technique and a non-linear structural solver: by doing so, we are able to exploit the well-known advantages of shock-fitting regarding the computation and modelling of gas-dynamic discontinuities to deal with fluid-structure interaction problems. More details about the proposed technique and some applications to inflatable structures in hypersonic flows are presented in this paper

  Abstract

  Knit, with its inherent flexibility and ability to integrate bespoke material performance, creates a promising alternative to traditionally woven membranes in architectural textile applications. The CNC-knitting technology allows for the manufacturing of membranes with gradient expansion properties by numerically controlling the distribution of varied stitches. In architectural knitted structures, material programming is used to achieve complex bespoke three-dimensional surfaces at a large scale, with a minimum residual waste during continuous digital manufacturing2–4. This permits to depart from the cut-pattern-based strategy commonly used for woven non-expandable membranes while allowing for the integration of multiple material properties in a single production process.
