ANSYS Piston-Cylinder Pressure Simulation

I am looking for a precise ANSYS Fluent (or Mechanical if you prefer FSI) model that captures the overall pressure gradient of Daphne 7373 oil inside a piston-cylinder-type cell while accounting for temperature-dependent properties. My goal is to understand how the pressure field evolves throughout the stroke and how it redistributes once thermal effects are introduced. Scope of work • Build or refine the piston and cylinder geometry I will supply (simple STEP file). • Assign material properties for Daphne 7373, including its temperature-dependent density and viscosity. I can provide a data sheet; feel free to extend it with correlations you have used successfully before. • Apply a realistic loading sequence: piston movement, initial fill pressure, and the temperature profile I will share. • Run steady-state and transient analyses that reveal the overall pressure gradient rather than just peak spots. • Deliver contour plots, gradient vectors, and a concise discussion of the results so I can compare them with lab measurements. The final hand-off should include the ANSYS project files so I can rerun or tweak the settings later. Acceptance criteria • Mesh independence demonstrated with two mesh sizes. • Pressure gradient plots along the cylinder axis for three key time steps. • Maximum residuals below 10-4 for each solver iteration. When you apply, highlight your direct experience with temperature-coupled fluid simulations in ANSYS, especially any work involving hydraulic oils or piston assemblies. A brief note on how you will treat the thermo-physical properties of Daphne 7373 will help me gauge fit quickly.
