Hi, I’m trying to simulate a 60-degree sector mesh of a light duty diesel engine using FLUENT. I am using non-premixed combustion with pilot, main, and post injections. I need help on plotting the Pressure against Crank Angle Degrees but in the “Report Plot” under “Monitors”, there are only options for against flow-time or time step on the X-Axis label.
May I know how can I specifically ask FLUENT to plot against Crank Angle Degrees? Thank you in advance.
Hi, If you want to plot a parameter versus angle, you have to define the angle for the ANSYS Fluent. You can define the angle by expression and plot pressure versus angle in Fluent or CFD Post.
Hi Sir, thank you for the reply. Do I have to define the angle by expression using the Expression Report Definition? Sorry, I am quite new to Fluent.
Hi,
I checked your problem. This can't be done in Fluent, but you can define the angle and export that with pressure and plot in other software such as Excel.
I did this for the pressure coefficient on the cylinder in cfdpost in the video below. (In this project, the center of the cylinder is the point (0,0). If the center of your sector isn't this point, you must correct the equation.
