Abstract
Nanofluids, or a variant of nanotechnology that consists of nanoparticles evenly suspended throughout a base fluid, are renowned for their ability to enhance thermal properties and assist with heat management applications. One common use of nanofluids is to regulate the heat of electronic devices, as the properties of the nanoparticles make them ideal for heat extraction.1 However, nanofluids are expensive, and nanoparticles themselves are extremely toxic to the human body. A recent study proposed a method for producing cost-effective and non-toxic nanofluid from instant coffee grounds.2 Data from the study suggests that the nanofluid is fit for DASC (Direct Absorption Solar Collector) applications, but little else is known about the nanofluid’s properties. The purpose of this independent study is to explore the properties of nanofluid droplets, namely impact behavior and heat transfer mechanisms, in order to evaluate the performance of this new sustainable nanofluid, and evaluate its ability to contend with traditional, non-sustainable options. Experimentation throughout the semester revolved around focusing the IR camera on water droplets and the chromium substrate to prepare for imaging the nanofluid droplets. As such, this report will serve as a guide to focusing the IR camera. Hopefully, future students will use these tips if their research involves infrared and thermal imaging.
