Rotational TENG COMSOL Simulation
Budget: $250 – $750 USD
I am running a study on a rotational triboelectric nanogenerator (TENG) and need a COMSOL-based model that mirrors my lab results almost point for point. Above everything else, the accuracy of the predicted AC voltage and current is critical, so please be confident in extracting clean electrical outputs from transient, electrostatic and electromechanical physics.
Scope of work
• Build a 3-D model that can sweep rotational speeds from 300 rpm up to 1500 rpm (for the second and third biomaterials we will test 1500 rpm only).
• Configure fifteen grating-number cases from 1 to 36 segments for the first biomaterial, plus a fixed 6-segment case for the other two.
• Simulate both contact and non-contact operation and give me a direct comparison between modes; that comparison is the main focus of the modal study.
• Run all scenarios for three biomaterials and make sure the voltage/current trends match the experimental curves I will share with you.
• Package the results as graphs and raw exportable data tables for AC voltage and current.
Knowledge transfer
Before hand-off I need to know exactly where in the model to adjust RPM, blade count and material definitions, so a short walk-through call or step-by-step document is part of the job.
Deliverables
1. Parametric COMSOL (≥ v6 preferred) model file with fully defined physics, studies and post-processing nodes.
2. Plot files or embedded plots showing the comparative behaviour of contact vs. non-contact modes.
3. Brief report summarising how well each run matches the experimental trend lines and noting any divergence.
4. One live session (or recorded video) demonstrating how to tweak RPM, segment number and biomaterial properties.
Timing
I would like everything wrapped up in 35–45 days; if you can improve on that without sacrificing accuracy, let me know.
I am open to adjusting the payment schedule in line with milestones and your level of experience. Please confirm your familiarity with triboelectric models in COMSOL, and include a quick note on any similar work you have completed.
