Plotting Heat Release Rate Graph in Fluent

goldencattogoldencatto Member Posts: 2

Hi, I am simulating a 60 degree sector mesh of diesel combustion in FLUENT and I need some help on plotting the graph for the heat release rate or rate of heat release as I could not seem to find a way to plot it under the "report plot" section.

Thank you in advance.

    Thank you for the reply.

    I am trying to plot the heat energy that is released during combustion due to compression when the piston is reaching Top Dead Centre. I tried plotting using the Report Plot>Flux Report>Total Heat Transfer Rate but the graph gave me negative values. I also tried using total surface heat flux under facet and vertex averages but they also gave me negative values. My boundary conditions for my wall temperatures are set to 450K.

    negative value means the heat transfers out of the system
