Climatic modelling of a closed vertical greenhouse (image is just as an example of the concept, the actual model is different) The job includes work in OpenStudio: - 3D modelling based on a 3D model that will be provided or import of an existing building (6 meter wide x 6 meter long x 6 meter high - open space with some technical equipment installed) The job includes work in EnergyPlus: - output from OpenStudio and definition of all parameters - modelling of the building and the industrial process of plant growth The job includes analytical reasoning of the results. Inputs will be provided for: - details of the insulation type to be used will be provided - a list of heat and humidity generators and expected output of heat and humidity for each - surface area of plants and water (for a sp...

Hi, I’m working on a colored flame candle development project and I’m looking for guidance from someone with chemistry experience. Objective:Create solid molded candles (not gel/container candles) that burn with bright visible flame colors such as red/magenta, green, and orange, ideally visible even in daylight. Key constraints for the project: Manufacturing must be simple and scalable. No complicated synthesis or multi-step laboratory reactions. Only cheap, easily available chemicals that can be sourced easily in the market. The candle should also support fragrance oils (scented candle). Avoid highly toxic compounds or chemicals that may create breathing hazards. Prefer materials that could realistically pass consumer product safety approvals. What I need help with:I...

Freelancer Brief – 3D Modeling Task We are developing a premium ergonomic cervical pillow made from molded memory foam. We need a parametric 3D CAD model suitable for industrial design and engineering simulation. Key requirements: • Dimensions: 600 x 350 mm pillow • Dual height: 95 mm and 120 mm • Central ergonomic cavity for the head • Cervical support ridge • Smooth ergonomic transitions • Manufacturing-ready geometry for foam molding Deliverables: • Parametric CAD model • STEP file • Native CAD file • 3 render views (top, perspective, section) The design should look premium and ergonomic similar to products from Tempur, Emma, or Cushion Lab, but must be original.

I need a design review for an electric heater with fan and heating element due to field failures. The specific issues are overheating and electrical shorts. Key Focus Areas: - Electrical Circuitry: Review and identify design flaws - Overheating: Analyze potential causes - Electrical Shorts: Investigate and recommend fixes Ideal Skills and Experience: - Expertise in electrical engineering - Experience with heating appliances design - Problem-solving skills for safety issues

I need a complete, production-ready design for a 100 W LED luminaire that will serve as the main light source in a living-room setting while still being robust enough for occasional outdoor use. The fixture must deliver high lumen output with excellent efficacy, maintain color stability over time, and integrate smoothly with common smart-home ecosystems (Wi-Fi, Zigbee, or similar). Scope of work • Component selection: high-efficiency LED array, constant-current driver, thermal interface materials, optics, housing, and an IP-rated enclosure or coating suitable for indoor/outdoor crossover use. • Electrical design: full schematic and PCB layout for the LED driver, MCU or smart-control module, surge and polarity protection, and any required EMC filtering. • Thermal manag...

I need a seasoned academic writer who can craft a 4,000–5,000-word manuscript on “Molecular Design of Silicone Adhesives with Thermal Resistance at 500 °C and Synergistic Acid-Thermal Aging Mechanism,” polished enough for submission to an EI-indexed journal. Scope and focus The paper must be organised in my custom structure—Abstract, Literature Review, Methodology, Findings, Discussions and Implications—with particular strength in the Analysis and Results content. You will be drawing on up-to-date polymer chemistry and materials-science literature, then translating experimental insights into a clear narrative that highlights how molecular design choices translate into sustained performance at 500 °C, especially under combined acid and thermal stress...

- Perform full CFD combustion simulation of a small combustor chamber (LPG or propane fuel, non-premixed combustion model) in ANSYS Fluent Student Version only(max 1000000 cells). - Use a non-premixed PDF combustion model with my PDF table (already created), mass flow inlet BCs (air 0.338 kg/s, fuel 0.0106 kg/s), and correct velocity directions from dome holes. - Run mesh independence study (4–5 meshes) and report outlet total temperature, residuals, and computational time until mesh-independent result is achieved. - Extract and calculate convective + radiative heat flux or temp on liner walls, total heat loss to walls (target ~8–10% of heat input), and wall temperature distribution. - Perform **steady-state thermal analysis** inside Fluent: import the CFD heat flux or wall t...
