I need a full-physics CFD model that captures how water boils when gravity is virtually absent, such as aboard the ISS. The set-up must be three-dimensional and treat the problem as a multiphase, conjugate heat-transfer case so solid–fluid coupling is resolved along with the liquid–vapour interface. The core phenomena I want you to resolve are: • Bubble formation • Heat transfer rate • Phase change dynamics Please build the model around water at atmospheric reference pressure, specify all governing equations and material properties, and explain any micro-gravity body-force implementation you use in the solver (ANSYS Fluent, OpenFOAM, COMSOL or a similarly capable tool is acceptable). I expect mesh files, solver settings, post-processing scripts, and a short technical note that discusses grid independence, time-step sensitivity, and key results such as wall heat flux and average bubble departure diameter. If you can also supply visualisations (iso-surfaces, temperature contours, and an animation of bubble evolution) that will complete the package.

Hi there, I would be happy to assist with the 3D microgravity boiling simulation. With strong experience in multiphase CFD, phase-change modeling, and transient thermal simulations, I can deliver accurate prediction of bubble dynamics, heat transfer, and interfacial behavior under microgravity conditions. Approach: 3D geometry preparation with microgravity boundary conditions and thermal loading Transient multiphase setup using VOF or similar interface-capturing methods to track liquid–vapor evolution Implementation of suitable phase-change models and conjugate heat transfer Mesh refinement near bubble interface and heated walls for stable numerical convergence Post-processing of temperature fields, vapor fraction, heat flux, and bubble growth behavior Deliverables: Complete CFD setup files with validated solver settings Visualization of bubble dynamics and phase distribution Heat transfer and flow behavior analysis under microgravity Technical report with methodology, assumptions, and recommendations Timeline: To be determined after discussing project scope. Budget: Open to negotiation based on complexity. Looking forward to collaborating on this project. Let’s connect to discuss further. Best regards, Arati M.
