1. Content.

This package includes two executable files: OpenWAM and WAMer.
The first one is the calculation code. The second one is the
interface used to generate the model. WAMer only works under
windows operating system but you can run in Linux using wine.
WAMer interface is in English.

2. Source code.

You can download the source code from the following git
repositories:

3. Linux notes.

  • The model must be built using Wamer.exe. This inteface is
    only compiled for windows. You can use it in linux with wine
wine Wamer.exe
  • To run the model use the following command line
./OpenWAM.bin model.wam

4. Changelog

Version 2.2

  • Homogenized some phisical and mathematical constants in the
    code.
  • Initialized some variable to increase the robustness.
  • Solved different bug of previous version.
  • Correcte some critical bugs in gasoline engines.

Version 2.1.0

  • Modified the procedure to calculate in-cylinder pressure.
  • Added the possibility to include an injection rate.
  • Modified the calculation of the gas properties in the cylinder.
  • Soved some bugs reading the sensor input data.
  • Modified the input data to the rotary disk. Added some
    multipliers to better control of the discharge coefficient.
  • Solved some bugs in the calculation of twin turbines and have
    been adapted to be used with the manufacturer maps.
  • Added some multipliers to the compressor map.
  • Solved some bugs in the engine and PID controller. Added
    dwell time to the PID controllers.
  • Solved some bugs in the fuel controller and in the VVT actuators.
  • Code optimization which reduce more than 4 times the time
    consumption.
  • Other optimizations and solution of bugs.

Version 2.0.3

  • Solved bug in the actuator of the fuel.
  • Solved bug in the VVT actuator.
  • Solved bug for supersonic flow in boundary conditions.
  • Solved bug for species tracking in branches.
  • Solved bug in the species mass balance in 2 strokes engines.
  • Solved bug in the calculation of gamma in the cylinder.
  • Modified the calculation of the fuel for petrol engines.
  • Modified correlations for gamma calculation in the cylinder.
  • Added compressor map extrapolation capabilities.

Version 2.0.2

  • Solved a bug in the injection of fuel for spark ignition
    engine.
  • Solved bugs in the calculation of the pipe properties using
    TVD schemes.
  • Important memory leak solved.
  • Solved a bug in the calculation of the specific heat ratio in the
    cylinder.

Version 2.0.1

  • An important bug has been corrected where the engine was
    modelled as spark ignited engine. That means, the fuel is
    calculated as a function of the air mass. The bug did that
    the fuel quantity was always equal to 0, independently of
    the air mass.
  • Some bugs have been corrected in the labels of the WAMer.
  • A button has been included in WAMer to run the model directly.
  • It is possible to define the path of the OpenWAM.exe.

Version 2.0.1

  • Some modifications have been intruduced in the code to be
    compiled in Visual Studio 2008.
  • Bug corrected in the combustion model (ACT).
  • Bug corrected in the engine valves.
  • Bug corrected in the heat transfer calculation in exhaust
    pipes.
  • Bug corrected in the reference parameters for the SAE
    compressor map.
  • Added new icon to the .exe file (Only in Windows)

Version 2.0.0

  • The OpenWAM code has been rewritten in order to be compiled
    it in any standard c++ compiler.
  • Lots of bugs have been corrected in WAMer interface. Some
    data were not stored when you change the values.
  • Some bugs have been removed from the calculation code.
  • New version of the ACT combustion model has been included.
