I need a CFD-based numerical model that zooms in on how well the liquid desiccant in my solar-thermal dehumidification set-up actually works. The goal is to predict desiccant effectiveness under real operating conditions, with special attention to three tightly linked mechanisms: the adsorption rate inside the contactor, the high-temperature regeneration process driven by the solar loop, and how desiccant concentration shifts over time. You are free to choose any reputable CFD platform—ANSYS Fluent, OpenFOAM, COMSOL, or an equivalent—as long as the final files can be opened and modified later. The geometry is relatively compact (a packed-bed absorber and a separate regenerator), yet the flow is coupled with heat and mass transfer, so please include conjugate heat transfer and ...

I am working on a university assignment that is already laid out in an AutoCAD (.dwg) file, but the drawing needs some professional polishing. The core of the job is to modify the existing design—nothing is being created from scratch—by both adding new features that my professor requested and correcting the errors I have spotted. Here is what I need from you: • Update the current drawing with the additional elements I will specify (dimensions, small component blocks and a couple of call-outs). • Fix the inaccuracies and layer issues I have flagged so the file prints cleanly at scale. • Return a tidy, well-organised .dwg plus a PDF plot so I can submit it without surprises. The file is ready to send right away, and I can point you to every spot that nee...

Hi I will share the details with the shortlisted candidates. Thanks

I have a complete reinforcement layout in one DWG but, for submission, each structural member must live on its own drawing sheet. What I need is straightforward: open my DWG, copy the relevant views into new layout tabs, and produce five separate sheets—slab, beams, columns, staircase/landing and footing (the exact views are already organised in model space). All call-outs, bar marks and title blocks must follow the annotation style in the template I will provide; please do not invent new symbols or text styles. Once the sheets are organised, return both the updated DWG (with clean, named layout tabs) and press-ready PDFs. Everything was drafted in AutoCAD 2023, so keep the files in native DWG format—no exporting to DXF unless I request it later. If you are comfortable wi...

We work with single-family residence in California that needs a complete fire sprinkler layout, covering the entire interior as well as the garage and exterior overhangs. All drafting must be done in AutoSPRINK so I can integrate your files directly into my permit package. Because the job falls under California’s C-16 scope, every detail has to track Cal Fire, NFPA 13D, and the latest California Fire Code amendments. I’m looking for a designer who is familiar to those standards, understands the hydraulic criteria local reviewers expect, and can build the plan set so it is essentially review-ready on first submittal.

I’m bringing a “smart” ashtray-cum-dustbin to crowded markets and need a product designer who can turn the concept into manufacturable reality. The unit will be a compact, plastic body that houses two clearly separated zones: a fire-safe metal insert for cigarette butts and ash, and a small bin for general litter such as wrappers. Because it will sit in busy outdoor corridors, the entire shell must be easy to hose down or wipe clean without trapping residue or odors. Key goals • Detailed 3D design (CAD) that specifies plastic grades, wall thickness, and the removable metal cup/liner. • Mechanisms that make daily emptying fast yet secure—think snap-fit or slide-out inserts—while keeping the exterior sleek for prominent brand graphics or municipal...

I need detailed engineering schematics for an audio-visual system and would prefer they be created directly in the XTEN-AV platform. The project is strictly technical—this is not about marketing visuals or animated promos—so every drawing must be precise enough to guide installers and integrators without further clarification. Here is what I expect: • Clean, layered XTEN-AV files (or equivalent CAD files if you propose a better tool) that map signal flow, rack layouts, cable schedules, and device elevations. • Consistent symbol libraries and line weights so the set can plug straight into our standards. • A PDF set exported for review plus the native, editable project files at hand-off. If you are faster or more comfortable in a different pro-AV design pla...

A small residential project requires a concise structural analysis so I can confirm the integrity of a few load-bearing elements before moving ahead with renovation drawings. The scope is intentionally tight: review the existing plans I will supply (PDF and DWG), run the necessary calculations in the software you are most comfortable with—ETABS, SAP2000, STAAD or similar—and return a clear, signed summary report highlighting any overstressed members and recommended fixes. The house is conventional construction, two stories, no complex geometry. I already have material specs, live/dead loads and soil data compiled, which should speed things up. Your deliverable is simply the calculation package and a brief narrative explaining any required reinforcement or alterations; no new d...

Dear Sir/Madam, I am the inventor and assignee of newly granted U.S. Patent US 12,612,951 B1, "Helical Tubular Compression Spring" (filed Sep 28, 2025; granted Apr 28, 2026). This architecture integrates guiding and spring functions into a single compact tube: a non‑circular guide‑rod follows a first helical path while a complementary slider bore follows a second path. A designed pitch‑length mismatch bends the guide elastically to deliver a programmable restoring force — enabling non‑linear force curves via geometry and materials. It excels in constrained recoil systems, high‑cycle actuators, and A&D/automotive mechanisms where conventional wire coils limit fatigue life and packaging. High‑spec spring/actuator segments exceed USD 30B SAM (various market reports). T...
