Virtual Functional Product Development of a µ-Methane Steam Reformer
A micro steam methane reformer is a complex product consisting of multiple units. For the virtual functional product development it is necessary to validate these sub models separately. Therefore a reactor was designed to analyse kinetics of chemical reactions. The reactor design is ... Per saperne di più
Benchmarking Tailored Formulations of Multiphase Flow in Porous Media
Nowadays, gas and nuclear waste storage, shale gas and EOR exploitation rise the need to understand and predict the fate of multiphase flows in the underground. Various formulations for multiphase flow arise from different linear combinations of governing equations and choice of ... Per saperne di più
An Equivalent Kd-based Radionuclide Transport Model Implemented in COMSOL Multiphysics® Software
Radionuclide sorption is often simulated using a lumped approach where retention processes are represented by the distribution coefficient (Kd), which relates the radionuclide mass retained in the solid phase to its aqueous concentration. Classical Kd-based simulations rely on two strong ... Per saperne di più
Application of COMSOL Multiphysics® Software in Transport Phenomena Educational Processes
Introduction Use of simulation software for solving realistic engineering problems has grown significantly in recent years due to the availability of less expensive but more powerful computers and development of user-friendly yet robust codes. From an educational perspective, students in ... Per saperne di più
Mechanistic Modeling of Non-Spherical Bacterial Attachment on Plant Surface Structures
The particle tracking model provided a deeper understanding to the experimental results. The model showed good agreement with experimental data for rotation, transport and attachment. In the attachment model, protrusions create low velocity, low shear regions increasing attachment ... Per saperne di più
Comparison of Diffusion Flux Models for Fischer-Tropsch Synthesis
The Fischer-Tropsch Synthesis (FTS) is a highly exothermic condensation polymerization reaction of syngas (CO+H2) in the presence of Fe/Co/Ru-based catalysts to produce a wide range of paraffins, olefins and oxygenates, the latter of which is often called syncrude. Multi-Tubular Fixed ... Per saperne di più
Fluid Motion Between Rotating Concentric Cylinders Using COMSOL Multiphysics® Software
Introduction Fluid flow patterns in research or process-scale equipment where a fluid is contained between concentric rotating cylinders in the absence of bulk axial flow has received notable attention in the field of fluid mechanics. Annular flows occur in many practical applications, ... Per saperne di più
A Wall-Cooled Fixed-Bed Reactor Model for Gas-Phase Fischer-Tropsch Synthesis
In the early 1920’s, Gas-To-Liquids (GTL) and Coal-To-Liquids (CTL) technologies were developed to account for the depleting crude oil resources [1]. During this period, Franz Fischer and Hans Tropsch developed a process to convert synthesis gas (syn gas), derived from coal ... Per saperne di più
Hydrodynamic Modeling of a Rotating Cone Pump Using COMSOL Multiphysics® Software
Introduction Velocity profiles in liquid films flowing over rotating conical surfaces are of considerable interest in industry. The efficiency of important process equipment, such as spinning cone columns, fluid degassers, centrifugal disc atomizers, centrifugal film evaporators, and ... Per saperne di più
Development of a User Interface for Design of SO2 Oxidation Fixed-Bed Reactors
H2SO4 is a very important chemical commodity, and indeed, a nation’s H2SO4 production has been a reasonably good indicator of its industrial strength for the last century or so1,2. Nearly 350 MM tons of H2SO4 was produced in 20143.The demand for H2SO4 in United States exceeds the supply ... Per saperne di più
