Despite rapid improvements in the performance of central processing unit (CPU), calculation cost simulating chemically reacting flow using CFD remains infeasible many cases. The application convolutional neural networks (CNNs) specialized image field prediction has been studied, but need to develop a network design fitted for recently emerged. In this study, model introducing finite volume meth...

Abstract Pillar collapses are events that due to their severe consequences can be classified as high risk. The design of pillars in underground room-and-pillar operations should migrate risk-based approaches. authors this work proposed a pillar methodology integrates stochastic discrete element modeling for strength estimation, and finite volume (FVM) stress estimation. This paper focuses on th...

Abstract Sloshing describes liquids motion in the semi-filled tanks, and exerts dynamic loading on its walls. This effect is of great importance in a number of dynamic systems e.g. aerospace vehicles, road tankers, liquefied natural gas carriers, elevated water towers and petroleum cylindrical tanks. Pressures insert impacts which are important for structural strength evaluation and its co...

Abstract In this study the isogeometric B-Rep mortar-based mapping method for geometry models stemming directly from Computer-Aided Design (CAD) is systematically augmented and applied to partitioned Fluid-Structure Interaction (FSI) simulations. Thus, newly proposed methodology geometries described by their Boundary Representation (B-Rep) in terms of trimmed multipatch Non-Uniform Rational B-S...

This study computationally investigates the heat transfer characteristics in a double-pipe counter-flow heat-exchanger. A heated viscoelastic fluid occupies inner core region, and outer annulus is filled with colder Newtonian-Fluid-Based Nanofluid (NFBN). mathematical model developed to conjugate exchange properties from hot NFBN. The modelling formulation of given problem comprises system coup...

This study computationally investigates the hydrodynamics of different serpentine flow field designs for redox batteries, which considers Poiseuille in channel and Darcy porous substrate. Computational Fluid Dynamics (CFD) results in-house developed code based on Finite Volume Method (FVM) conventional (CSFF) agreed well with those obtained via experiment. The deviation pressure drop was less t...

Selecting an optimal bow configuration is critical to the preliminary design of polar ships. This paper proposes approach determine ships based on present numerical simulation and available published experimental studies. Unlike conventional methods, integrates both ice resistance calm-water with navigating time. A method icebreaking vessel going straight ahead in level developed using SPH (smo...

effect of water gas shift reaction (co+h2o=co2+h2) on wustite reduction has been investigated by a transient, non-isothermal mathematical model based on grain model. in this model, wustite porous pellet is reduced using syngas, namely a mixture of hydrogen, carbon monoxide, carbon dioxide and water vapor. for this purpose, governing equations containing continuity equation of species and energy...

a subsurface drainage network mainly carries unsteady flow and data are not usually available for model parameters calibration in such networks. in the present research, the finite volume method using the time splitting scheme was employed to develop a computer code for solving the one dimensional unsteady flow equations. using corrugated sub drainage pipes, an experimental prototype setup was ...
