Dynamique des fluides computationnelle Jobs

I’m refining a cross-flow fan-wing UAV concept and need a complete picture of how it will behave in the air and how the structure will cope with the resulting loads. On the aerodynamic side, I want accurate lift and drag coefficients across the flight envelope, clear visualisation of flow patterns and vortex behaviour around the fan-augmented wing, and a detailed pressure distribution map that I can feed back into the structural model. CFD in ANSYS Fluent, OpenFOAM or an equivalent solver is fine as long as mesh independence is demonstrated and transitional flow around the fan is captured. For structural integrity, my main focus is the wing and fan structure plus the control surfaces and their attachments. I’d like an FEA model (Abaqus, ANSYS Mechanical, or similar) that impor...

We are looking for an experienced Product Design Engineer (Mechanical + Electrical) to lead the prototyping of a high-end, silent benchtop cocktail machine. Unlike traditional machines, this device relies on solid-state physics rather than mechanical moving parts to replicate the thermodynamics of a professional bartender. We have a complete Product Requirements Document (PRD) and preliminary architecture. We need you to take these requirements and build a fully functional "looks-like, works-like" prototype. The Engineering Challenge: The device replaces mechanical shaking and stirring with precision energy application. You will be engineering a system that integrates: Ultrasonic Cavitation (40kHz): For instant emulsification. Thermodynamics: High-power Peltier (TEC) modules ...

I have a gas-liquid separator whose internal geometry needs to be verified before fabrication. The task is a complete CFD study of multiphase flow through the vessel, capturing the interaction between gas and liquid phases. My main concerns are flow distribution across the internals, overall pressure drop, and the resulting phase-separation efficiency, so the model must resolve these three metrics quantitatively. A CAD file of the current layout, design operating conditions, and fluid properties will be supplied at project start. The simulation should be run at the specified throughput, using an appropriate multiphase model (VOF, Euler-Euler, or similar) in Fluent, CFX, OpenFOAM, or another recognised solver, with mesh independence demonstrated. Please include transient behaviour if it ma...

My process-piping circuits in an oil & gas service are beginning to show uneven wall loss and experience recurrent leaks, and I need a focused CFD corrosion-erosion study that pinpoints where failure will most likely initiate. Scope • Build a 3-D CFD model of the specified piping runs and flow paths. • Use the material properties and flow-condition data I will supply to simulate erosive particle impingement, wall shear stress, and corrosion-erosion coupling. • Generate a risk map that highlights high-rate thinning zones and ranks them by remaining life and likelihood of rupture. Key objectives – Predict failure points with enough accuracy to guide inspection planning and spool replacement. – Quantify local wear rates (mm/yr) and correlate them...
