Structural Design and Pressure Drop Analysis for ISS Experiment

NASA JSC’s Crew and Thermal Systems Division is designing an experiment to go aboard the ISS in February 2016 to test two phase change materials, water and wax, in a prototype heat exchanger. As an intern in the group during the summer of 2014, I had two primary responsibilities: (1) Design the support structure and electronics box in CAD and (2) build a program to estimate the pressure drop in the propylene glycol water (PGW) fluid loop.

Please see my exit presentation for the design methodology. You may also download the Excel program I created to calculate the PGW pressure drop.

I gained the following skills working on this project:

  • Creo 2.0 (CAD)
  • Design for assembly and manufacturing
  • Excel programming
  • Fluid analysis
  • 3D printing and prototyping
