I understand you need to numerically verify the flue gas extraction efficiency of a brick chimney for a typical domestic system, specifically concerning the risk of backdrafting into windows of a new building situated 1 meter away with a chimney height of approximately 2 meters, within the context of Prague's block housing. My experience with similar CFD analyses for building ventilation and exhaust systems, including the modeling of wind effects on building aerodynamics, directly addresses these concerns. I propose developing a robust CFD model using ANSYS Fluent. The approach will involve creating a detailed computational mesh of the chimney and surrounding environment, incorporating the specified 1-meter proximity and 2-meter elevation difference. Boundary conditions will be defined based on standard domestic heat source parameters (which I'm ready to receive), including inlet flow rates and temperatures for flue gases, and realistic wind profiles for the external environment. Steady-state simulations will establish baseline performance, followed by transient simulations to capture dynamic responses and potential backdraft scenarios. I will analyze pressure fields, velocity distributions, and species transport to quantify flue gas dispersion and assess the risk of re-entry. To ensure the most accurate and relevant results, could you provide details on the typical flue gas temperature and flow rate expected from the domestic heat source? Additionally, are there any specific wind direction or speed scenarios that are of particular concern for this Prague block housing context? I am available to discuss these details and my proposed methodology further at your convenience.

As a talented and technologically savvy professional with a wealth of experience in engineering and technical documentation, I am confident in my ability to tackle your CFD simulation project. My experience with multi-physics simulations, especially with ANSYS Fluent, equips me with the skills necessary to proficiently construct your CFD model and accurately simulate your brick chimney in both steady-state and transient regimes. Drawing upon my superior tech skills-using industry standard parameters, I'll adeptly construct boundary conditions for the heat system of your residence. I will meticulously evaluate pressure distributions, flow velocities and temperature fields along the path of the emissions, and subsequently identify their impact on the overall efficiency of the fume discharge. In addition, I'll provide you with a concise but comprehensive report complete with tables, graphs, streamlines images and actionable recommendations to improve shape or insulation. What sets me apart is not just my proficiency in ANSYS Fluent but also AUTOCAD which will come in handy for modeling should you be ably interested.

The core of this job is numerically verifying the flue gas exhaust efficiency of a brick chimney, specifically addressing the danger of flue gas re-entry into windows when a new building is placed close by, about 1 meter away, with the chimney extending about 2 meters above the roof. I will build a CFD model of the chimney in ANSYS Fluent. This will cover both steady-state and transient modes. I will define boundary conditions based on standard domestic heat source parameters. The output will be an evaluation of pressure, velocity, and temperature fields within the flue. This evaluation will calculate overall exhaust efficiency and pinpoint major loss areas, feeding into a concise report with graphs, streamlines, and potential modification recommendations. I'd build the steady-state model first to establish a baseline and confirm initial flow behaviour. Track record on here: 5.0 across 10 reviews, 100% on time and 100% on budget. What are the precise dimensions of the window openings you are concerned about re-entering flue gases? Provide standard domestic heat source parameters.

Hi there! The real risk here isn't just whether the chimney drafts—it's whether it drafts *consistently* in the specific wind and pressure environment of dense Prague block development. That 1m distance to a neighboring building creates complex flow recirculation patterns that static design calculations often miss. CFD will let us see exactly where downdrafts occur and whether exhaust can actually recirculate back into windows under winter conditions. I'd model this in steady-state first to establish baseline draft performance, then run transient simulations with variable wind directions and speeds typical for your area. That way you'll see not just the nominal case, but the worst-case scenarios. I'll focus the mesh refinement on the chimney exit and the cavity between buildings where recirculation matters most. You'll get full geometry files, the meshed model, and reproducible simulation setup so you can iterate later if needed. Before I start, it'd help to know: do you have the exact chimney dimensions and internal geometry (is it a simple rectangular clay flue, or are there offsets), and what exhaust temperature and mass flow you're designing for?

Hello, I can help with the CFD analysis of your brick chimney and evaluate the efficiency and safety of flue gas discharge. I have direct experience analyzing and designing industrial chimneys and flue gas systems for waste incineration equipment, including flow, temperature, pressure, velocity, and exhaust performance. I can develop the CFD model, analyze steady and transient conditions, identify potential recirculation/backflow areas, and provide clear plots, flow visuals, and recommendations for improving the chimney design. Please send the available chimney dimensions, heat source/flue gas specifications, and building layout so I can review the case and start the analysis. Regards

@bojans9

Hello, this is Bojan. Thanks for sharing the project. I want to be upfront: although I work in software development, backend systems, automation, and embedded engineering, I don’t take on CFD simulation work such as ANSYS/OpenFOAM modeling, chimney flow analysis, transient/steady-state runs, turbulence modeling, or thermal‑flow reporting. This requires a specialist in computational fluid dynamics with experience in combustion systems and architectural flow behavior. Since you need a full CFD model, boundary‑condition setup, pressure/velocity/temperature fields, efficiency evaluation, and a structured technical report, a professional in CFD simulation will serve you much better. I prefer not to accept work centered on advanced fluid‑dynamics modeling rather than engineering automation. If you ever need help with technical workflow planning or automation strategy, I can assist — but I’m not the right fit for this CFD project.
