CFD Simulations
In order to validate several design options and select a path forward, I sought to determine the flow rate, pressure drop, and Reynold's numbers of various tank geometries through laboratory testing and CFD simulations.
LAB TESTING
I began by gathering baseline data in the lab in order to establish a goal for pressure drop at various flow rates. I then set up devices with each of the new potential tank geometries and ran through the same pressure drop testing. Suspicious of the data, I re-ran all of the tests using a low pressure set-up and verified the results through on-device data collection with Cool Term. I then calculated the Reynolds number for each configuration and determined which one to prioritize moving forward.
SIMULATIONS & RESULTS
Once I determined which geometry to proceed with, I needed to validate the worst case scenarios. I modified the CAD to represent the LMC and ran CFD simulations using adaptive meshing functionality to compare the effects of the geometry changes on the flow restriction. Additionally, I performed a tolerance stack-up analysis using MMC to confirm worst case fit. I adjusted the tolerance specs based on the results of these efforts and DFM feedback.
Associate Mechanical Engineer
Continuum is a global innovation design firm that develops products, services, and experiences to improve people’s lives. My final co-op placement allowed me to work across the Mechanical and Electrical Engineering teams on several contracted projects, focusing on manufacturing development and validation. Due to the COVID-19 pandemic and government-mandated work-from-home order, the scope of my co-op was ultimately limited.
Mechanical Engineering Co-op
Ecosense Lighting is a start-up company focused on creating new technologies to change the way that the world views light. My second co-op placement allowed me to be a part of a fast-paced product development team, supporting existing products through feature additions, validation testing, and root-cause analysis. Furthermore, I got the opportunity to work on custom and next-generation products, designing for prototyping and manufacturing.
