CFD Combustion Simulation and Thermal static coupled analysis
Budget: $30 – $250 USD
- Perform full CFD combustion simulation of a small combustor chamber (LPG or propane fuel, non-premixed combustion model) in ANSYS Fluent Student Version only(max 1000000 cells).
- Use a non-premixed PDF combustion model with my PDF table (already created), mass flow inlet BCs (air 0.338 kg/s, fuel 0.0106 kg/s), and correct velocity directions from dome holes.
- Run mesh independence study (4–5 meshes) and report outlet total temperature, residuals, and computational time until mesh-independent result is achieved.
- Extract and calculate convective + radiative heat flux or temp on liner walls, total heat loss to walls (target ~8–10% of heat input), and wall temperature distribution.
- Perform **steady-state thermal analysis** inside Fluent: import the CFD heat flux or wall temperatures as boundary conditions, include conduction through 2 mm inner + 5 mm outer walls, and obtain final temperature field on the metal liner and casing.
- Export the converged temperature distribution from Fluent to **ANSYS Static Structural** (Student Version) for one-way thermal-structural coupling.
- In Static Structural, apply the imported temperature field as thermal load + pressure loads (505 kPa internal), fixed supports, and calculate thermal stresses, total deformation, and factor of safety on the combustor liner and casing.
- Deliver: full Fluent project files (.wbpz), mesh independence table, heat flux/thermal results (contours + values), static structural results (stress/deformation contours), and a short report (max 10 pages) showing all steps, formulas used, and results — everything must run on (Fluent Student Version only
