â€¢Please start the calculation with the option Output Control -> Results -> Extra Output Variables List â€¢Choose one variable for every Particle group you defined. â€¢Please choose any variable but Volume Fraction. This option activates an internal hook to write the mass flow variable of the particle tracks into the result file. â€¢You can evaluate the mass flow of the particles within your domain similar to the Eulerian phase variables. â€¢In ANSYS CFX please do the following (assuming HC Fuel as particle material name): â€¢Generate an Expression CharMassflowCalc = HC Fuel.Mass Flow * HC Fuel.Char.Mass Fraction â€¢Generate a variable referencing the Expression: Char Mass flow = CharMassflowCalc â€¢Create a plane where you want to calculate the massflow â€¢Bound the plane if necessary (Plane definition -> Geometry tab -> Plane Bounds) â€¢You can set the center of the bounding box if the plane is set by three points â€¢The first point specifies the center. â€¢Sum up the variable Char Mass flow over the plane: sum(Char Mass flow)@plane 1
