Multi-phase flows is simply any fluid flow system consisting of two or more distinct phases flowing simultaneously in a mixture with some level of phase separation at a scale well above the molecular level. A mixing layer is formed when two parallel streams of fluids are moving at different velocities such that the velocity at the fluid-fluid interface is non-zero. In the absence of dissipative forces such as viscosity, small perturbations at the fluid–fluid interface lead to the creation of vortices at the interface.For a particle-laden flow at this interface, these vortices will affect the flow of particles based on the particle mass. A particle-laden flow is a multiphase flow where one phase is the fluid and the other is dispersed particles. Governing equations for both phases are implemented in Ansys Fluent. This SimCafe Fluids Course was developed by Dr. Rajesh Bhaskaran, Swanson Director of Engineering Simulation at Cornell University and Chiyu Jiang in partnership with Ansys, and was last modified by Alumni Chiyu Jiang. It serves as an e-learning resource to integrate industry-standard simulation tools into courses and provides a resource for supplementary learning outside the classroom. In this tutorial, we will learn to model the 2D periodic double shear layer by following the end-to-end workflow in Ansys Workbench.

Combustion is a process that includes two processes viz. thermal and chemical in which a hydrocarbon fuel reacts with an oxidant to form products, accompanied by the release of energy in the form of heat. It is an integral part of various engineering applications like internal combustion engines, aircraft engines, rocket engines, furnaces, and power station combustors. Combustion simulation is used broadly during the design, analysis, and performance stages of the above-mentioned applications. In this SimCafe course, you will learn how to model axisymmetric case for cylindrical combustion chamber with the fuel (CH4) and air mixture. You will set up the boundary conditions needed for the simulation. The fundamental concepts and the steps needed to successfully model this fluid flow problem are explained using step-by-step instructions.

Most fluid flows (gas or liquid) are turbulent in nature. These flows are characterized by unsteady and irregular fluctuations of transport quantities such as mass, momentum and species in both space and time. These fluctuations enhance flow mixing. In this SimCafe course, you will learn how to model three dimensional internal turbulent pipe flow. You will create the geometry, the computational mesh and set up the boundary conditions needed for the simulation. The fundamental concepts and the steps needed to successfully model this fluid flow problem are explained using step-by-step instructions.
