Collaboration will be remote, but familiarity with regional suppliers and standards will make reviews and approvals faster...
I have already built and run a three-ramp scramjet inlet with an isolator in ANSYS Fluent for a freestream Mach of 6.8 at 300 K. The geometry and test conditions follow the reference study you will find here: https://www.mediafire.com/file/114w1th29a8pqyf/Impact+of+wall+cooling+on+the+stability+and+aerothermodynamic+performance+of+a+scramjet+ Although the solution reaches convergence, the peak coefficient of pressure is roughly 30 % lower than the paper reports, and the mass-flow prediction drifts in the same range. I am using the density-based solver, ideal-gas properties, and the SST-Transition turbulence model; wall cooling is included exactly as described in the article. Mesh quality looks acceptable on standard checks, yet the mismatch persists. What I need from you is a focused s...

I need a thorough structural calculation and performance check on a newly designed aluminum profile system, with special focus on the largest 3 m × 3 m configuration before cascading the findings to the smaller variants. The study must cover both static and dynamic load analysis so that I can confirm each profile, connection detail, reinforcement option, and fixing method is truly fit for purpose. Material fatigue is my prime concern, so the calculation package has to explore long-term cyclic effects alongside the usual strength and stiffness checks. If you spot joint failure or deformation risks during the process, flag them, but the fatigue life is the critical pass/fail criterion. Please ground every assumption in recognised codes and clearly document the input data, equations, ...
I run a complex System-on-Chip project and reserve about four hours each week for focused progress. During that window I rely on an experienced engineer who can jump straight into SystemVerilog / UVM code and keep our verification flow tight. The core of the session is SoC-level development with specific focus on PCIe, DDR, and GPU SoCs, yet every task circles back to solid design-verification practice: • Testbench development that plugs cleanly into our existing UVM environment • Live simulation and debugging, spotting corner-case failures as they appear • Coverage analysis and closure so we meet functional goals with data-driven confidence Remote pair-programming over a shared workspace works best for me; I’ll have source, waveforms, and spec documents ready...

I am building a proof-of-concept rover whose only job is to prove that controlled, repeatable motion is possible inside transformer oil. To make that happen I need a complete blueprint package—detailed engineering drawings rather than a simple overview—showing exactly how to propel, steer, and recover a small test vehicle submerged in this highly viscous fluid. Rather than propellers, tracks, or wheels, I want the craft to move by exploiting buoyancy. Your design should use the density difference between the rover and the oil to generate thrust and directional control. This should not create any bubbling in oil while movements. Critical elements of the buoyancy control system that must appear clearly in the drawings • Adjustable weights • Air / water pumps Ev...
