CFD-ACE+ provides several chemical reaction models that can
be used to study combustion process depending of the objectives of the study.
Accurate modeling of combustion phenomenon is important in a wide
variety of applications and is necessary to understand the complex
physics behind the combustion process. Reduced fuel consumption and
lower emissions are major motivators behind the increased interest in
combustion process. In this tutorial, the chemical reaction of a propane jet with a
co-flowing air jet is modeled through the finite rate chemistry model
available in CFD-ACE+.

Proton Exchange Membrane (PEM) fuel cell generates electrical energy by
transforming chemical energy produced through an electrochemical
reaction. These type of fuel cells are being considered for a wide
variety of portable applications including automotives and cell phones.
This tutorial introduces the user to the fuel cell modeling capability
available in CFD-ACE+ through its flow, heat transfer, electric and
electro-chemistry modules.
This tutorial presents a heat transfer study in realistic "shell and tube" heat exchanger.
The geometry is imported in CAD file format, while the mesh generation, solver setup and
post-processing (visualization of results) are performed with CADalyzer.
This example shows flow results obtained for a fan spinning at 3485 RPM. The following approach was taken to simulate the fan. A ugrid user subroutine is used to rotate the fan and shroud grid as a solid body. The parametric inputs, time step size and the user subroutine combined to rotate the fan by 2 degrees every timestep. The blades of the fan were given a "grid velocity" BC and the shroud was set with a "user specified" zero velocity to simulate a stationary shroud.
The reattachment length (i.e., the point where the separation bubble disappears on the channel floor) of a subsonic incompressible turbulent flow (Reynolds number based on channel height, Re = 10000) past a two-dimensional backward-facing step is estimated. This is a step-by-step guided introductory tutorial for setting up a flow model with turbulence in CFD-ACE+.
Turbulent mixing is important in a wide variety of applications. One such application is high speed air breathing aircraft engines (supersonic combustion/hypersonic aircrafts). As aircrafts continue to fly at higher speeds, complete mixing has to be achieved within shorter combustion chambers to minimize fuel consumption, avoid combustion instabilities and decrease emissions. The turbulent mixing of two streams of gases (propane and air) is modeled in this tutorial.
