Projectile Moving Inside a Barrel

Introduction The purpose of this tutorial is to illustrate how to set up and solve a problem using the following two features in FLUENT. Moving Deforming Mesh (MDM) using the layering algorithm. User-defined real gas law. The problem involves a projectile moving through a barrel and out of the muzzle. The flow is assumed to be inviscid. In this tutorial you will learn how to: Read a mesh file for performing an MDM calculation. Compile a UDF for the projectile motion and the Abel-Nobel real gas law. Set up the moving zones and hook the UDF in FLUENT. Run...

Simulation of a Steam Line Break with the IAPWS EOS

This Tutorial includes the following features: Using the IAPWS Library for steam and water properties Thermal phase change model to represent rapid vaporization Tracking a pressure pulse with a transient simulation (note: the test duration is fairly long and the time step required to fully resolve the traveling pressure wave is fairly short, so you will not run the entire simulation in this workshop) Adaptive timestepping for a transient run Comparison of simulation results to experimental data, and predictions from the SERAPHIM and RELAP codes Introduction Edwards Test – sudden depressurization of pipe section, well known test case in...

IC Simulation for Canted Valve Engine Using Hybrid Approach

Introduction Two approaches are employed in ANSYS FLUENT to solve in-cylinder (IC) problems, namely, hybrid approach and layering approach. The layering approach is used for engines with vertical valves like most diesel engines, while the hybrid approach is typically used for engines with canted valves like most spark ignited (SI) engines. For either approach mentioned above, IC problems solved in ANSYS FLUENT consist of three stages. Decompose the geometry into different zones and mesh them properly. By breaking up the model into different zones, it is possible to apply different mesh motion strategies to different regions in a single...
