Rigid Body FSI of a Moored Vessel

This workshop utilities the 6 degrees-of-freedom rigid body solver  in CFX The rigid body solver will be used to simulate the movement of a  model-scale hull, moored within a water testing tank A homogeneous multi phase approach is taken to simulate the free surface A moving wall condition will be applied to generate some wave patterns and fluid-structure  interaction with the hull Overview The computational domain is rectangular and half-symmetric The hull is positioned to give sufficient space both fore and aft (for wave and wake generation) and in the beam direction The domain is open at the stern...

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...

Solving a Gasoline Direct Injection Engine Simulation

A three dimensional single cylinder CFD simulation, of a 4-stroke spray guided Gasoline Direct Injection(GDI) Spark Ignition (SI) engine, is performed in this tutorial. Detailed boundary conditions are shown in Figure 4.1: Problem Schematic (p. 173). Engine simulation is started from Intake valve opening (IVO) and fuel is injected during the intake stroke. Homogeneous fuel air mixture is compressed and spark ignited 15° before compression Top Dead Center (TDC).[1] [1] Download Tutorial Coming Soon …. —————————————————— [1]...
