Human Comfort

The purpose of this project was to design and implement an autonomous system based on Arduino to monitor environmental parameters that intervene in the perception of human comfort such as temperature, humidity, and solar radiation, and use them to analyze factors related to climate control and energy efficiency in buildings. The system was tested in laboratory conditions as well as by in situ measurements of building elements and living spaces. Some of the experiments carried out were contrasted with numerical simulations that allowed us to understand the implemented system.

The search for energetic alternatives and the concern about water preservation are novel ideas that challenge the humanity. This project was inspired in these challenges, being based in the utilization of solar energy for desalination of brackish water. A parabolic solar concentrator captures the solar radiation heating thermal fluid, which is closed-circuit circulated into a evaporator, which has three trays. The first has the functions of storing, pre-heating and condensing. The second works as an evaporator and the third stores the evaporated water. The system was tested with and without pump. The thermal fluid temperature reached 105°C and the amount of evaporated water reached 15kg/day. The equipment meets the social demand for sustainable inventions.

Front Speed

In a glass furnace solid batches of material are fed into a chamber and radiation heating applied. An individual batch is melted over the course of several minutes to form molten glass. A travelling front within the batch designates the progress of the melting, a process characterized by multiple radiation reflections. This results in an effective conductivity within the melting zone that is significantly larger than that in the unmelted batch. Approximations based on these disparate conductivities enable accurate explicit expressions for the almost constant melting front speed and the associated temperature profile to be derived. Our results compare favourably with existing numerical simulations of the process, with the advantage of being both analytic and relatively simple. These predictions may be useful in suggesting how a furnace might be most effectively controlled under varying batch conditions, as well as ensuring the quality of the glass sheets produced.
