These past 2 weeks we came up with some parts to increase turbulence and mixing to enhance binding probabilities. We will test these devices this week.   This is a model of turbulent flow through a part similar to the ones we designed showing the desired effect of fluid mixing that we hope to achieve.

This week we brainstormed ideas to increase turbulence with Dr. Xi. We designed our ideas in solidworks to be 3D printed and used with our system. We also did some testing using formulas from deliverable 5 to measure a specific amount of nanoparticles. We used 3.4 grams mixed into 1 liter of water and four of our ceramic magnets. Using four magnets, we collected more nanoparticles than the previous test, but we will next try our experiment with neodymium magnets, which are much stronger.

This week, the Power Puff Girls worked to conclude some testing. The testing showed that the nanoparticles, or in this case, iron oxide shavings, were able to collect on the magnets, but not the quantity desired. Further explanation of the testing can be seen in the previous post. Figure 1: A Screenshot showing the COMSOL modeling of fluid flow in spiraled tubing. Figure 2: A second screenshot showing the COMSOL modeling done. From there, the Girls worked on developing ways to generating more turbulence flow. Jeannette and Jennifer worked on coming up with ideas for potential turbulence apparatuses. Esther and Emily continued the COMSOL modelling and were able to represent the flow in a spiraled tubing. The models can be seen in figures 1 and 2. For future testing and modeling, Jennifer and Jeannette are working to generate a more accurate testing method and apparatus. Also, Emily and Esther will continue to model the different tube designs  as well as the magnet ...

This week, our team started simulating our project's design in comsol and formulated our design architecture. Below are the images displaying our work in this week figure 1: Comsol simulation of the project comsol simulated one of the ideas of our project: - the geometry of our project - fluid flow - magnetic strength The following Image shows our design architecture. It is compartmentalized into different sections which are: 1. patient: Two reservoirs (one being the source of the fluid, and the other, where the fluid is returned) will be used to symbolize the patient. 2. Power: This includes the pump that will be pushing water and its power supply 3. injection site: where the nanoparticles will be injected into the fluid. 4. Turbulence: This will be part of the geometry that acts to increase the turbulence 5. collection site: This will be a bag embedded with magnets into which blood will flow for magnetic nanoparticles to be collected. 6. Extraction site: where nan...
