Description and Convergence Order Analysis of the Finite Element‐Volume Spatial Discretization Method

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
This article presents the principles of Finite Element‐Volume discretization and conducts an analysis of its properties and convergence orders. The discretization ensures local mass conservation, second‐order convergence for velocity, and first‐order convergence for pressure.

Production and Characterization of Open Cell Cordierite from Boron and Waste Materials by Geopolymer Method for the Emission After Treatment System of Diesel Engines

open access: yesGlobal Challenges, EarlyView.
Open porous geopolymer‐based cordierite materials are produced due to the porous structure, temperature resistance, easy and low cost applications of geopolymer. For the composition of cordierite, waste boron clay, metakaolin, fly ash and magnesium carbonate are used, while keeping the geopolymerization temperature constant, sodium silicate, sodium ...
