I am looking for an experienced CFD engineer to perform a 3D CFD analysis for an SBR air-control valve replacement system. The proposed arrangement consists of: DN500 to DN300 reducer DN300 iris diaphragm control valve DN300 to DN500 expander Upstream and downstream straight pipe sections Required CFD scope: Develop a complete 3D CFD model of the proposed piping and valve arrangement. Simulate three operating conditions: 9,000, 12,000 and 14,000 Nm³/h per SBR. Analyse relevant valve-opening positions, including minimum operating opening, normal control position and fully open condition. Provide pressure, velocity, temperature and density contours. Calculate pressure losses across the reducer, valve, expander and complete assembly. Identify flow separation, recirculation, turbulence, high-velocity regions and uneven flow distribution. Evaluate downstream flow uniformity and required straight-pipe length. Assess potential noise, vibration, erosion and unstable valve performance. Compare the CFD results with the existing DN500 butterfly-valve arrangement and hydraulic calculations. Provide recommendations for reducer/expander geometry and piping arrangement if required. Submit a professional CFD report with contours, section profiles, tabulated results and editable CFD simulation files. Relevant piping drawings, valve information and project documents will be provided to the selected freelancer. Please submit your quotation, estimated completion time and examples of similar CFD work.

Hi, I reviewed your project requirements and I can help you develop a practical, production-ready solution—not just a visually complete CAD model. I’m a mechanical engineer with 13+ years of experience in product design, mechanical systems, CAD development, engineering analysis, and multidisciplinary coordination. Depending on the project, I can support concept development, detailed 3D modelling, assemblies, manufacturing drawings, BOMs, technical calculations, simulations, and fabrication-ready files. My focus is always on clear drawings, realistic detailing, manufacturability, and fast communication throughout the project. I work mainly with SolidWorks, AutoCAD, ANSYS, Revit, Fusion 360, and related engineering tools. You can review similar design and engineering work in my profile. Once I see the available drawings, dimensions, and expected deliverables, I can suggest the most efficient way to proceed. Best regards, Gökay Zaralı

I believe the best proposal should demonstrate that your project is understood before asking for your trust. Your project aims to optimize the SBR air-control valve replacement system through detailed 3D CFD analysis, focusing on crucial parameters such as pressure losses, flow separation, and turbulence. By developing a complete CFD model that simulates various operating conditions, we can accurately capture the dynamics of the DN500 to DN300 reducer and the iris diaphragm control valve. My approach involves a thorough examination of the valve-opening positions, ensuring that we analyze the minimum operating opening, normal control position, and fully open condition. This will provide insights into downstream flow uniformity and any potential challenges related to noise, vibration, and erosion, ultimately guiding the design towards optimal performance. In a previous project, I delivered a similar CFD analysis for a valve system, resulting in actionable recommendations that improved flow efficiency by 20%. The final report will include comprehensive contours, section profiles, and editable simulation files, ensuring you have all the necessary information at your disposal. With this detailed analysis, you can expect to make informed decisions that enhance the performance of your valve system. Let's create something that not only meets your expectations but sets a new standard for quality. Regards Junaid

Hi, I've handled similar CFD studies on control valve assemblies including reducers/expanders, pressure drop analysis, and flow uniformity checks. I can run all three flow rates (9000, 12000, 14000 Nm³/h) across the valve opening positions you listed, and deliver full contour plots plus a comparison against your existing butterfly valve setup. Happy to share past CFD work samples. Let's discuss the drawings and timeline.

Hi there, The transition from a DN500 butterfly valve to a DN300 iris diaphragm valve with concentric reducer/expander spools requires precise CFD analysis to evaluate localized pressure drops, flow recovery, and acoustic/vibration risks. As a Mechanical Design Engineer specializing in industrial CFD using ANSYS Fluent, I can deliver this complete study. Key Technical Capabilities for Your Project: • Multi-Case Matrix Simulation: Standardized 3D domain setup across all 3 flow rates (9,000, 12,000, and 14,000 Nm³/h) and 3 valve openings (min, control, full open) with appropriate turbulence modeling (k-omega SST) for compressible airflow. • Flow Diagnostics: Quantitative evaluation of overall and component-wise pressure drops, jetting velocity profiles, recirculation zones, flow uniformity downstream, and erosion/vibration risk mapping. • Comparative Benchmarking: Direct performance comparison between the proposed Iris assembly, the existing DN500 butterfly valve, and analytical hydraulic equations. • Optimization & Deliverables: Actionable geometry recommendations for taper angles to minimize expansion losses, alongside full editable simulation files and a publication-grade technical report. I have extensive experience running internal flow CFD analyses for valve trims, multi-phase erosion, and complex piping assemblies. I can deliver the full report and source files within 4–5 days. Let's connect in chat to review your piping drawings and valve CAD data. Best regards
