Alexey S.

I provide CFD and multiphysics modeling support using COMSOL Multiphysics and OpenFOAM, with a focus on internal flows, non-Newtonian and viscoelastic fluids, and polymer-processing applications.

I can help with:
- Velocity and pressure distributions in channels, pipes, and process equipment
- Pressure-drop calculations and comparisons of operating conditions or geometry variants
- Non-Newtonian flow modeling with clearly stated material assumptions
- Mesh-refinement studies and convergence checks for the quantities that matter
- Linear-static structural FEA with analytical cross-checks, where appropriate

Deliverables can include native simulation files, exported numerical data, flow-field plots, and a concise technical report documenting the model setup, assumptions, results, and limitations.

Each study starts with a review of the geometry, material properties, boundary conditions, and required outputs. I distinguish solver convergence from mesh sensitivity and validation against measurements or reference solutions. When essential inputs are missing, I clarify them before presenting engineering conclusions.

Send a short project description, your geometry, and operating or loading conditions so we can define a practical scope and the required deliverables.
