Dear all,
I'd like to draw your attention to the Fortissimo working group for OpenFOAM, where a webinar will given by Reza Nouri's presentation entitled "mADM1 - A multidimensional parallel numerical solver of ADM1 model for anaerobic digesters in OpenFOAM framework", on Wednesday, Oct 17th at 14:00 CEST (13:00 BST). Abstract Anaerobic digesters (ADs) are closed reactors that produce biogas from waste materials. ADs are highly complex systems, which comprise circa three tens of different chemical species that are advected with the flow, promoted by propellers. The optimisation of these devices aim to maximize the biogas production, and, at the same time, minimize the energy consumption, for instance by minimizing the propellers running time or by establishing the most effective cycle for feeding and digestate renewal. In this complex framework, most of the design activities are in general based on trial-and-error procedures, which do not guarantee optimised performances. The current high demand of alternative energy resources has increased the number of ADs in service and motivate the search of improved design procedures for these devices. One of the first attempts to model the operation of ADs was made by the ADM1 model [1], a bulk model that comprises 47 variables and 109 coefficients. However, the ADM1 assumes homogeneous conditions that are in general far from the real situation. More recently, Gaden [2] proposed a multidimensional solver, developed in OpenFOAM framework, which was able to cope with the inhomogeneous distribution of the relevant quantities. The main limitation of the solver developed by Gaden [2] was the lack of parallelization, which limits the use of the tools on a regular basis. The project where this work is comprised is being developed in the framework of one of the Fortissimo 2 European project experiments, and join different entities with complementary skills to develop and experimentally assess a solver appropriate to model the operation of ADs, which is able to take advantage of HPC facilities, aiming to establish and disseminate effective design procedures for these systems. This work describes the solver implemented in OpenFOAM to model the operation of ADs, and the preliminary verification activities.
