Workshop 08a Tank FlushingIntroductionWorkshop Description: In this workshop, you will model the filling and emptying of a water tank. The simulation will be multiphase (volume of fluid) and transient (time dependent)Learning Aims:This workshop aims to teach skills in running multiphase simulations in Fluent. The entire simulation approach is covered, including:Setting up a 2-phase simulationUsing ‘patch’ tools to control initialisationPreparing a transient animationUsing Solution Controls to modify the problem definition (turn off the valve)Learning Objectives: This workshop teaches skills in the use of multiphase modelling, transient flow modelling, generating images on-the-fly and preparing animationsIntroductionIn this workshop, you will model the filling and emptying of a water tank. The transient problem is solved as a multiphase (air/water) simulation using the volume of fluid (VOF) multiphase model.An initial water level is set in the tank. The water supply is turned on for the first second of the simulation and then shut off for the rest of the simulation. The water level rises until water flows out the U-tube generating a siphoning effect which effectively empties the tank.Mesh ImportStart a new Fluent session- 3D, Double Precision and Display Mesh After Reading (Display Options)Read or import the mesh file tankflush.msh.gzUse the parallel processing operation if it is available on the training computersClick General in the outline treeScale the mesh to units of cmSet “View Length Unit In” to cm to have Fluent display lengths in centimetersVerify the domain extents:–11 x 20.5 cm–20.25 y 26.5 cm 0 z 1 cm Check the meshMesh ImportOrientate the viewSelect ‘Graphics and Animations’ in the outline treeClick ‘Views’ button in the center paneIn the panel that opens select ‘front’ under Views and click ‘Apply’, click ‘Auto Scale’ and then ‘Close’AmbientInletOutletDefine Simulation TypeIn the General PanelChoose Transient SolverEnable Gravityset Gravi
