Tutorials
Tutorials show you how to use Simcenter STAR-CCM+ for various applications in a step-by-step format with recommendations for setup, initialization and steps of the solution process specific to the application. Macro and simulation files are available for download for a large proportion of cases.

  - Complex Chemistry: Methane-Air Jet Flame
    This tutorial demonstrates how to set up and solve a complex chemistry simulation to model finite-rate chemistry in a flame.
  - Spray Combustion: n-Dodecane
    In this tutorial, you simulate spray combustion using the Steady Laminar Flamelet (SLF) model with the Soot Method of Moments model.
  - Flamelet Generated Manifold: Perfectly Premixed Combustion with Adaptive Meshing
    This tutorial simulates lean perfectly-premixed propane combustion using the Flamelet Generated Manifold (FGM) model in a combustor where the flame is stabilized behind a V-shaped bluff body. The Large Eddy Simulation (LES) model is used to directly resolve the large scales of the turbulence, and model the small scale motions, in the flow domain.
  - Surface Chemistry: Methane on Platinum Oxidation
    This tutorial models methane on platinum oxidation using complex chemistry models.
  - Reacting Channels: Steam Methane Reforming
    In this tutorial, you use the Reacting Channel Coupling co-simulation model in Simcenter STAR-CCM+ to solve a reacting flow simulation using the same method as is required for systems such as: reformers, crackers, and process heaters.
  - Acoustic Modal Analysis: Thermo-Acoustic Stability of a Cylindrical Burner
    Thermo-acoustic instability, that is, large-amplitude pressure oscillations, can be encountered in many devices such as gas turbines, rocket engines, or combustors. The instabilities, which can have detrimental consequences, are excited by the feedback loop between the unsteady combustion and the natural acoustic modes of the devices.
  - Eddy Break-Up: Coal Combustion
    The combustion of pulverized coal is still one of the main primary energy conversion mechanisms worldwide.
    - Prerequisites
      The instructions in this tutorial assume that you are already familiar with certain techniques in Simcenter STAR-CCM+.
    - Loading the Starting Simulation File
      For this tutorial, you are provided with a starting simulation file that contains the mesh operations necessary for generating a 2D axisymmetric mesh of the coal combustor.
    - Selecting Physics Models
      The standard EBU version of the Eddy Break-Up model is used to represent the combustion reactions that occur within the coal combustor, since the reaction rates are limited by the rate at which turbulence mixes the reactants and heat into the flame zone.
    - Setting Material Properties
      Since the composition of different types of coal varies, it is important to define the correct composition of the type of coal that is used in the combustor.
    - Defining Reactions
      Due to the heating of the coal particles, the coal volatile matter is released to the gas phase. The coal volatile mixes with the surrounding gases to undergo an oxidation process. In this tutorial, you specify the gas phase reactions in two steps.
    - Defining the Coal Particles
      The Lagrangian Multiphase model is used to define the interaction between a discrete phase of solid coal particles and the continuous background phase of the fluid domain within the coal combustor.
    - Setting the Initial Conditions
      Before the combustion occurs, hot air is present in the coal combustor. High initial temperature assists with coal devolatilization and ignition so it is not necessary to define an ignitor.
    - Setting the Boundary Conditions
      The coal particles transport air enters the computational domain through a velocity inlet boundary at a constant velocity of 23 m/s. The combustion air flows in as a radial velocity profile with a swirl around the axis. You specify this velocity profile as a radial table with respect to a local cylindrical coordinate system.
    - Defining the Coal Particle Injector
      The injector introduces coal particles into the reactive domain in a given direction, at a specified rate. The diameter of the coal particles is defined using the Roisin-Rammler method.
    - Specifying Solver Parameters
      To let the flow solution stabilize initially, the flow and energy solvers run without the Lagrangian solver for 500 iterations in the beginning of the simulation. The DO Radiation and the Lagrangian solver update only every 20th iteration, which speeds up the runtime of this tutorial.
    - Monitoring and Plotting Carbon
      You compare the mass of carbon entering the computational domain with the mass of carbon leaving it. When the two mass flow rates reach the same value, you can assume that the solution has converged.
    - Visualizing Coal Combustion Products, Temperature, and Velocity
      You visualize the distribution of the mass fraction of CO, CO₂, and SO₂ as well as the temperature in the form of contour plots. The velocity field is displayed as a line integral convolution plot.
    - Running the Simulation
      You set the stopping criteria before running the simulation.
    - Visualizing the Results
      You load the track file that contains the coal particles tracks after the simulation has finished.
