Dynamique des fluides computationnelle Jobs

I’m completing a university project that calls for a full engineering design of a two-flange ball valve suitable for crude-oil service. The assembly—including body, ball, seats, stem, seals, and fasteners—must be laid out in stainless steel and verified against API 6A. While references to API 6D or 608 can guide good practice, every dimension, tolerance, and material choice has to pass an API 6A compliance review. What I need from you is the complete digital design package created in a mainstream CAD environment (SolidWorks or Fusion360). The file should be able to make edits and easy to revise for future FEA or CFD checks. Deliverables • 3-D solid models of the full valve assembly and each component (.STEP + native CAD files) • Detailed 2-D fabrication dr...

Contexto: Comparar duas geometrias de caixa de gordura industrial (uma ABNT e uma modificada) e confirmar melhora nos parâmetros que avaliam a sedimentação. Premissas e modelagem: Geometria fixa das caixasEntrada com fluxo constante de uma mistura totalmente imiscível (modelo Volume of Fluid) de água, óleo e de uma certa quantidade pré determinada de particulas discretas (modelagem de Lagrange), passivas (ou seja, que não afetam o escoamento), com diâmetro constante, sujeitas às forças gravitacional, de empuxo e de arrasto. O diâmetro das partículas será usado como parâmetro para calibrar o modelo com os dados reais. Ou seja, algumas simulações da caixa ABNT serão rod...

- 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 t...

I am completing an dissertation that couples CFD with structural-piezoelectric analysis in ANSYS. The core of the study is piezoelectric actuation: fluid flow drives a smart structure, the structure feeds back to the flow, and both responses must be validated against a published research paper. Here is what I need from you: build the clean geometry, generate a high-quality mesh, run the transient CFD in Fluent, transfer loads into Mechanical for the structural and piezoelectric response, then bring everything back together for a convergence study and result comparison. Because this is academic work, every modelling choice has to be fully explainable. I will rely on you most heavily when it comes to solver settings—that is the area I find most challenging—so be ready to justif...

I have a 3-dimensional model that will be evaluated under turbulent flow conditions, and I need a clean, high-quality mesh prepared in ANSYS Workbench. The mesh must be fine enough to capture boundary-layer behaviour without driving cell counts to impractical levels, as it will be fed directly into a full CFD solver later. What I will supply • The native CAD file (SOLIDWORKS) . What I need back • The complete ANSYS Mechanical/Fluent mesh file (.msh or Workbench project) ready to run. • A short note outlining element count, y+ target, inflation layers used, and any local refinements you added for anticipated high-gradient regions. Acceptance criteria 1. Mesh conforms with best practices for turbulent flow in 3D, including inflation layers near walls. 2. No negative volumes...
