Explosion Venting Analyzer (EVA)


Files needed to run EVA


================================

MCRInstaller.exe

INPUT

EVA.exe


1. Prerequisites for Deployment

  • Verify the MATLAB Compiler Runtime (MCR) is installed and ensure you have installed version 8.0 (R2012b). NOTE: You will need administrator rights to run MCRInstaller. Please find the MCRInstaller within the package

    2. Definitions of the files


    MCRInstaller.exe :
    this file is only required for any MATLAB stand alone application. Once it is installed, you may use it for any other MATLAB stand alone application.


    INPUT.txt:
    This file gives the user the flexiablity of modifying the input variable of the EVA.

    Line 1: sim_repeat = 3; sim_repeat is the number of the repeatation of the EVA. User can modify the input file for each simulation time. This can give the user to compare the results of different cases.

    Line 2: filename = 'threecase.xlsx': The code is generating an excel file. All the plotted results are in this excel file. User can change the name of the excel file.

    EVA: EVA is designed for 3 different flame speed formulations and 2 different ignition (rear and center). Therefore each single plot has 6 different sets. These date sets are stored in excel files. There are three plots (Mass vented, Flame speed and Pressure) for each simulation time.
    In the excel file the user may access the following data structure

    Mass Vented 

     Case1:sl_opt_1_r_ig	Case1:sl_opt_1_c_ig	Case1:sl_opt_2_r_ig 

     Case1:sl_opt_2_c_ig	Case1:sl_opt_3_r_ig	Case1:sl_opt_3_c_ig


    Flame speed 

     Case1:sl_opt_1_r_ig	      Case1:sl_opt_1_c_ig	Case1:sl_opt_2_r_ig 

     Case1:sl_opt_2_c_ig	      Case1:sl_opt_3_r_ig	Case1:sl_opt_3_c_ig


    Pressure 

     Case1:sl_opt_1_r_ig	Case1:sl_opt_1_c_ig	Case1:sl_opt_2_r_ig 

     Case1:sl_opt_2_c_ig	Case1:sl_opt_3_r_ig	Case1:sl_opt_3_c_ig

    Defination of the case
    Case1:sl_opt_1_r_ig: flame speed formulation 1, and rear ignition
    Case1:sl_opt_2_c_ig: flame speed formulation 2, and central ignition

    Note: The curious users are reffered to "A Computational Solver for Gas Explosion Venting" by Ugarte et al.


    Run the simulation:


    Please double click on the EVA.exe file. The simulation will start. Then follow the instructions on the program.
