Hi there, I can support the 2-stroke engine CFD and cycle-development work, including 1D gas-dynamics/time-area calculations, scavenging architecture, transient moving-mesh CFD, DI spray/mixing, and combustion optimization. I have strong experience in ANSYS Fluent CFD, transient multiphase flows, moving/deforming meshes, turbulence modeling, and thermal/flow simulations. I can develop the workflow around the custom piston motion, 150 Hz operating condition, supercharged intake, and very short injection window, with focus on trapping/scavenging efficiency, pumping losses, BSFC and emissions trends. I can deliver the optimized port/piston geometry, pressure-volume data, operating-condition studies, and a clear engineering report. Timeline and budget can be finalized after discussing the complete scope. Could you share the initial engine geometry/piston motion profile and available fuel/combustion data? Best regards, Arati M.

Hi, At Vutuk Design and Media, we bring over 15 years of mechanical engineering, advanced numerical CFD simulation, thermal modeling, and high-end technical visualization expertise. Our engineering team conducts full 3D transient in-cylinder engine simulations using ANSYS Fluent—combining dynamic mesh movement with multiphase fluid physics to optimize combustion chamber design, port flows, and thermal efficiency. To help us scope your engine CFD modeling framework: What specific engine layout (single-cylinder research engine, multi-valve automotive, or two-stroke/four-stroke heavy duty) are we simulating? What are the key operating boundary conditions (engine RPMs, intake manifold boost pressure, fuel injection timing, wall temperatures)? Are there specific performance goals, such as reducing pressure losses across the intake valve or optimizing swirl ratio? Would you like photorealistic 3D rendered cutaway visuals or animated velocity/temperature vector videos produced for presentation reports? We invite you to visit our profile and portfolio page to evaluate our past numerical fluid simulation and 3D visual showcase work. Let's discuss your project! Best regards, Vutuk Design and Media

Hello, As the engine project requires a mix of creative problem-solving and high technical expertise, I believe I am the ideal candidate for the job. With my engineering background and extensive skills in 3D Modeling, CAD Design (SolidWorks, AutoCAD, CATIA), and Mechanical Simulations & Analysis (including FEA and CFD basics), I am well-equipped to handle tasks like architecting the scavenging layout, optimizing combustion chemistry, or producing performance reports. To tackle the precise requirements of the project such as dynamic variation of the compression ratio or direct injection within barely 2 ms timeframe, I plan to utilize Ansys Forte for moving mesh simulations while employing EngMod2T for efficient 1D/3D coupling. These software stack combinations guarantee accuracy, efficiency, and an ability to execute complex tasks.

The high-frequency operation and extremely short fuel injection window present a significant risk for achieving proper fuel atomization and mixing before combustion. I handle this risk by using specialized CFD solvers, such as ANSYS Fluent, configured for transient, high-speed turbulent flows and coupled with detailed spray models to accurately predict droplet breakup and mixing within the < 2 ms timeframe. I will build the mathematical model of the working cycle and design the gas exchange architecture using AVL BOOST, then use CFD to optimize combustion, aiming for maximum fuel efficiency and minimum exhaust emissions on your 2-stroke engine. The result will be an optimized combustion chamber geometry and injection strategy for your 3.2 kW, 150 Hz power unit. For the dynamically variable compression ratio, will you be modeling this as discrete steps or a continuous function? I need the initial geometry of the cylinder and porting to begin the CFD analysis. I have a 5.0 rating across 10 reviews on here, and Preferred Freelancer status.

@revival786

Greetings! SCAVENGING I can model your 2-stroke engine working cycle, design the gas exchange architecture, and optimise combustion before prototyping, with the goals of lowest BSFC and minimum emissions. I will propose and justify the scavenging layout based on efficiency, then run 1D time-area calculations to size the ports and determine the cylinder bore needed for 3.2 kW at 150 Hz with a 40 mm minimum stroke under your non-sinusoidal piston motion and dynamically variable compression ratio. I will build a 3D CFD model with moving mesh and AMR to simulate gas exchange and optimise port and piston crown geometry for maximum trapping and scavenging efficiency with minimal pumping losses. I will also model the direct injection process and combustion chemistry within the sub-2 ms window, optimising injection timing and swirl or tumble for complete combustion and low emissions. Deliverables include optimised CAD geometry for the liner ports and piston crown, a performance report covering BSFC, indicated thermal efficiency, and emission trends, supercharger specifications for absolute pressure and mass flow, and P-V diagrams across fuel loads for your control system. For the software stack, I would use CONVERGE CFD or Ansys Forte for the moving mesh and DI combustion work, coupled with GT-POWER or EngMod2T for 1D and 1D/3D analysis, with OpenFOAM as an alternative. Thanks, Revival
