Steam Condenser CFD Simulation
Budget: £250 – £750 GBP
I’m running a steady-state, two–phase condensation model for a single steam-carrying tube placed inside a rectangular duct through which the cooling medium flows. The goal is to quantify heat-transfer efficiency along the tube wall and map local condensation behaviour.
All pre- and post-processing must be done in ANSYS Fluent – that is the environment my wider workflow depends on. I already have basic geometry and material data; what’s missing is a robust setup that captures phase change, solves for the temperature field on both sides of the tube, and outputs wall heat-flux, overall U-value, and condensate distribution with mesh-independent accuracy.
Key points
• Physics: two-phase (steam → liquid) condensation, steady-state, turbulent flow inside and outside the tube
• Primary metric: heat-transfer efficiency (local and overall)
• Required models: appropriate condensate treatment (VOF or Eulerian film), turbulence model suitable for internal flow, energy equation with latent heat
• Domain: single tube, rectangular duct; inlet, outlet, and wall boundary conditions supplied once the NDA is signed
Deliverables
1. Fluent case & data files ready to run/restart
2. A brief setup note covering mesh strategy, models, and boundary conditions
3. Summary report (plots of temperature, volume fraction, wall heat-flux, and calculated HTC)
Acceptance criteria: residuals <10-5, heat-balance closure within 2 %, and mesh sensitivity demonstrated on at least two grid densities.
Please let me know your expected turnaround and any similar work you have validated before; I can share geometry immediately once we agree on scope.
