COMSOL Day: Fluid Flow & Chemical Transport

See what is possible with multiphysics modeling

Modeling and simulation (M&S) has become an important method for fostering new ideas and designing and optimizing processes and devices in areas such as environmental technology and the chemical, food, and pharmaceutical industries. The study of transport and reaction phenomena is also relevant in the automotive and aerospace industries.

COMSOL Multiphysics® and its add-on products have become very popular in the modeling of fluid flow, chemical species transport and reactions, porous media flow, and nonisothermal reacting flow. In addition to modeling capabilities for laminar, turbulent, and multiphase reacting flows, COMSOL® features multiphysics capabilities for describing fluid–structure interaction, electrokinetic flows, and other phenomena coupled with reacting flow.

Join us for this COMSOL Day to learn more about COMSOL Multiphysics® and its add-ons for modeling transport and reaction phenomena.

Schedule

11:00 a.m.

COMSOL Multiphysics® and its add-on CFD Module and Chemical Reaction Engineering Module are highly versatile when it comes to modeling and simulation involving fluid flow with chemical species transport and reactions in industries such as the bulk chemicals, specialty chemicals, pharmaceutical, biochem, consumer products, environmental tech, and petrochemical industries. The software's capabilities cover laminar and turbulent flow, multiphase flow, and nonisothermal reacting flows.

In addition to its wide range of capabilities for reacting flow, the software features unique multiphysics modeling functionality for coupling reacting flow with rotating machinery; electric fields in electrochemical cells and electrophoretic separation; as well as conjugate heat transfer with solids, fluids, and porous media. Using the Application Builder, it is also possible for modeling and simulation specialists to create simulations apps with user interfaces specialized for specific purposes, making the benefits of simulation available to a larger community of engineers and scientists within an organization.

Join us in this session to get an executive overview of the content of this COMSOL Day. We will introduce you to the functionality in COMSOL Multiphysics® for modeling fluid flow, transport of chemical species, reaction kinetics and thermodynamics, separation, mixing, multiphase flow, polymer flow, porous media flow, and heat transfer. We will also show how users have benefited from simulation apps and implementing the COMSOL® software into their processes.

Turbulent Flow

The study of the impact of turbulent flows on the design of processes and devices is efficiently done using CFD. The use of COMSOL Multiphysics® and the CFD Module has become popular for these types of modeling and simulation studies.

The CFD Module features a wide range of turbulence models (9 Reynolds-averaged Navier–Stokes, or RANS, turbulence model interfaces), from the simpler algebraic models such as the algebraic yPlus model to the more advanced SST and v2-f turbulence models. In addition, the CFD Module also includes several large eddy simulation (LES) and detached eddy simulation (DES) models. All of the modeling interfaces for turbulent flow can also be coupled with other phenomena to describe fluid–structure interaction, rotating machinery, and nonisothermal flow with conjugate heat transfer, to name a few examples.

Join us in this session to get an overview of the capabilities of the CFD Module for modeling turbulent single-phase and multiphase flow.

Reacting Flow & Reaction Kinetics

As numerical methods and computers have become more powerful, modeling of transport and reactions has trickled down from large companies' R&D departments and national labs to almost every company and organization working with reacting systems. The Chemical Reaction Engineering Module and CFD Module, add-ons to COMSOL Multiphysics®, are widely used for analyzing reaction kinetics, thermodynamics, and reacting flows in chemical reactors, catalysts, sensors, devices for chemical analysis, and other related processes.

The modeling features provided in COMSOL® include multicomponent transport in dilute and concentrated solutions as well as reacting laminar and turbulent flows. Reaction systems can be defined simply by typing in chemical equations; the corresponding space- and time-dependent material, energy, and momentum equations are then automatically generated. This approach renders the modeling of reacting flows both uniquely efficient and user-friendly. The Chemical Reaction Engineering Module also features an extensive thermodynamics database for computing heat of reactions as well as other thermodynamic properties of liquids and gases.

Join us in this session to get an overview of the features in COMSOL® for modeling and simulating chemical reaction kinetics and reacting flows. We will discuss how to set up a model, starting with the entry of chemical equations, followed by the generation of space- and time-dependent models.

Heat Transfer

COMSOL Multiphysics® and its add-ons are widely used for understanding and designing processes and devices involving fluid flow and heat transfer. The Heat Transfer Module together with the Chemical Reaction Engineering Module is able to describe laminar and turbulent reacting flows in combination with conjugate heat transfer between solids and fluids. Heat transfer through radiation can be accounted for using surface-to-surface and surface-to-ambient methods as well as methods for heat transfer in participating media.

COMSOL® also includes unique capabilities for seamlessly coupling nonisothermal flow with conjugate heat transfer and radiation with other phenomena, such as Joule heating; thermoelectric effects (Seebeck effect, Peltier effect, and Thomson effect); and fluid–structure interaction.

Reacting Flow in Porous Media

Many industrial processes are based on heterogeneous catalysis in porous media. Understanding these processes and then improving them can have great economic and environmental impacts. Modeling and simulation of reacting flow in porous media plays a key role in understanding and optimizing such processes.

COMSOL Multiphysics® and its add-on products feature a wide range of functionality for modeling of reacting flow in porous media and have therefore become popular tools in the field. The COMSOL® software also provides unique functionality for studying transport and reactions in systems with a bimodal pore structure (microporous and macroporous): so-called multiscale models.

In this session, you will learn: how multiphysics simulation enables analyses from a microscopic particle level to a macroscopic reactor level, how multiscale approaches can be used within a model to describe bimodal pore structures, and more.
