This lecture presents a bachelor's project at EPFL focused on designing an experiment to illustrate convective effects in heat and mass transfer. Inspired by Nuki Yama's pool boiling experiment, the instructors detail the setup, challenges faced, and the final design involving a bi-container experiment with the possibility to change the working fluid and pressure. The lecture covers the iterative process of building the experiment, from initial plans to the final model made of stainless steel sheets, safety glass, and aluminum wire clamps.
