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 ...

I hold a recently granted U.S. patent for a next-generation noise-abatement system for internal-combustion engines and now need a thorough, simulation-driven validation of its performance. Scope of work 1. Create a 3-D CFD model from my drawings (to be shared after a preliminary call and NDA). 2. Run steady- and transient-state CFD simulations to confirm there is no increase in backpressure compared with typical commercial mufflers. 3. Perform an acoustic simulation that clearly demonstrates: • Frequency reduction • Overall noise level improvement • Noise distribution at the outlet 4. Cross-reference all results against benchmark data from standard mufflers. 5. Compile findings in a polished, marketing-ready PDF report that highlights: • F...

Scope of Work: Hydraulic Simulation of Water Spray Manifold System I require a hydraulic simulation of a water spray piping manifold installed inside a circular drum. The objective is to verify that each spray hole (nozzle) receives the required pressure and flow rate under the given operating conditions. The manifold distributes water through multiple small spray holes, and the simulation should confirm whether the design achieves uniform flow distribution and minimum pressure requirements at each spray point. Objectives: The simulation should determine: Pressure distribution along the spray manifold. Flow rate through each spray hole. Verification that each spray hole receives: Minimum pressure: 2.5 barg Minimum flow rate: 2.5 L/min Identification of any uneven distribution or pressu...

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...
