FDS-01: SIMPLE FLUID FLOW ANALYSIS USING FDS (FIRE DYNAMICS SIMULATOR) TOOL In this tutorial a window is created which is treated as inflow of air with velocity of 2.5 m/s having temperature of 5 C. The outflow conditions is treated at top of the office, and the boundary condition is set as open to atmosphere  The steps are followed in this tutorial are listed below::   Step I: create header syntax file to start program in FDS software.   &HEAD CHID='office'/ Note: office is user defined name of FDS function/ file.   Step II: create syntax for simulation flow time.   &TIME T_END=15.0 Note: 15 sec is simulation flow time, which is solved in FDS software.   Step III: create syntax for initial temperature of domain.   &MISC TMPA=45.0/   Note: 45 C is initial room temperature, which is provided in this tutorial. Following three syntax is must for every FDS function.   Step IV: Create syntax for geom...

Tutorial 04 : CFD analysis of water falling on cylindrical surface using interfoam solver of OPENFOAM. Figure 4.1 (a) Initial volume fraction (VF) of water Contour of free water falling with BCs Figure 4.1 (b) Meshed domain of water falling Problem Identification In this problem investigation of free water falling using OPENFOAM is proposed for multi phase modeling (free water falling cooling), in which water is flow in free water falling from prescribed location section from top initial condition (see figure), which is assumed at surface of top side wall (See the following figure). Air and water properties are selected from literature available in digital medium. Outlet is at top of the domain which is selected for continuity effect of free water falling system. Some assumptions are applied in this problem like initial room temperature is assumed at constant value for this problem (ISOTHERMAL). Air and water properties are also assumed constant for this problem. ...
