COMSOL Day: Fluids & Heat

See what is possible with multiphysics simulation

Join us for a full-day online event focusing on the crucial physics of fluids and heat. You will have the opportunity to meet COMSOL technical staff and COMSOL users across many industries.  

This event will feature presentations and demonstrations of COMSOL Multiphysics® simulations involving fluid flow and heat transfer. As this is a broad topic, the schedule is arranged with several parallel sessions, giving you the opportunity to choose from a range of talks, including specific applications like pipe flow and metal processing and more general issues like solving large CFD problems and nonisothermal flow.

We welcome both experienced COMSOL Multiphysics® users and those who are new to the COMSOL® software to attend. Feel free to invite your colleagues. Register for free today!


Welcoming Remarks

COMSOL Multiphysics® version 6.0 is coming soon! This session will touch upon the highlights of the new release:

  • Model Manager: Major new functionality that allows colleagues to collaborate and centrally organize models and apps, including access and version control as well as advanced search
  • Uncertainty Quantification Module: A new product that includes tools for uncertainty quantification, including design of experiments
  • Increased efficiency in solving surface-to-surface radiation
  • Flow-induced noise
  • Improved large eddy simulation (LES) with automatic wall treatment and thermal wall functions
  • Control of the thickness of the boundary layer mesh for CFD and node trimming
Polymer Flow Modeling

Non-Newtonian fluids are found in a great variety of processes within the polymer, food, pharmaceutical, cosmetics, household, and fine chemical industries. Examples of these fluids are coatings, paints, yogurt, colloidal suspensions, aqueous suspensions of drugs and lotions, and suspensions of peptides and proteins, to mention a few.

The Polymer Flow Module, an add-on to COMSOL Multiphysics®, provides features and physics-based interfaces for the modeling and simulation of non-Newtonian fluid flow subject to viscoelastic, thixotropic, shear thickening, and shear thinning behavior. In this session, this is presented together with examples from industry.

Heat Treatment in Metal Processing

This session will introduce you to modeling the multiphysics of phase transformations and quenching of metals like steel using COMSOL Multiphysics®. With the introduction of the Metal Processing Module to the COMSOL® software product suite, it is now much easier to model solid-state metallurgical phase transformations that are affected by and dependent on other physical phenomena, as well as the resulting material behavior of the transformed metal. In addition to covering the modeling of metallurgical phase transformations and hardening, the presentation will also introduce the new Carburization physics interface and new functionality for importing material properties.

Pipe Flow & Pipeline Applications

Get a brief overview of using the Pipe Flow Module for fluid flow and mass transfer simulation within the COMSOL® software environment. We will also discuss multiphysics couplings for pipeline systems, such as coupling to heat transfer and pipe mechanics.

Radiative Heat Transfer

Radiative heat transfer is one of the three types of heat transfer and plays a major role in many applications. During this session, we will discuss different examples in order to help identify cases where thermal radiation has to be accounted for. Then, we will present the different physics interfaces for radiation modeling. Surface-to-surface radiation modeling capabilities will be described in detail. In particular, the options to define gray radiation and multiple spectral bands will be explored. Modeling radiation with different types of surfaces (diffuse, specular, and semitransparent) will also be presented.

Break for Lunch
Welcome Back: Some Useful Resources
Phase Change Modeling

Phase change plays an essential role in a wide variety of industrial processes, e.g., polymer manufacturing, metal casting, and freeze-drying. This session will focus on modeling a conjugate heat transfer problem with phase change. We will demonstrate how the phase transition can be modeled by a moving boundary interface according to the Stefan problem, and we will also explore other options to include phase change in your modeling with COMSOL Multiphysics®.

Multiphase Flow Modeling

Flows, including multiple thermodynamic phases, are relevant in several industrial applications ranging from microfluidics, such as droplet transport and inkjet printing, to large-scale applications, such as fluidized beds or the simultaneous flow of oil, gas, and water through pipelines. In this session, we will explore the different classifications of multiphase flow and discuss which tools and features within COMSOL Multiphysics® can be used to solve different scenarios.

Turbulent Flow Modeling

Most flows in real-world applications involve turbulence, e.g., flow past hydrofoils, flow in heat exchangers, HVAC systems, industrial-scale mixers, and pipe networks. In this session, we will discuss the turbulent flow modeling capabilities in COMSOL Multiphysics®, including RANS models, treating flow near walls, LES models, and common multiphysics couplings.

Mixer Modeling

Mixers with rotating parts are used in many industrial processes, such as the production of consumer products, pharmaceuticals, food, and fine chemicals. This session will focus on modeling transport problems in mixers and stirred vessels. We will discuss flow in rotating machinery with both frozen rotor and sliding mesh methods, free surface modeling, and parametric geometry parts for mixing applications.
