This is a series of other projects completed during my undergraduate career in Biosystems Engineering.
For this project, I was required to design a heat exchanger to cool an algal aquaculture system. The heat exchanger would be able to be implemented in the field in order to keep an aquaculture at the optimal temperature to promote healthy growth. The design required use of Stella modeling to determine some of the necessary design parameters, as well as an excel spreadsheet to make calculations. A set of temperature sensors called a HOBO took temperature readings throughout the test period. This PowerPoint presentation discusses the entirety of the project using a voiceover by the group.
This spreadsheet represents the equations and calculations necessary to determine the appropriate dimensions and temperatures for the heat exchanger. These equations involve a thermal energy balance and the caluclation of Nusselt, Prandtl and Reynold's numbers.
This poster depicts a project in which I was required to use my knowledge of biological kinetics to develop and carry out a biological process. This project entailed the use of an oxygen-inhibiting compound, sodium sulfite, to produce hydrogen gas from an algal growth. Stella modeling was used to determine the mass balance, and gas chromatography readings were taken over a period of 15 days in order to determine the compounds present in the sealed containers.
This document is the proposal for a consulting firm that is being developed for a sustainable project planning class. This consulting firm would work with local breweries in the Greenville area to improve their sustainability initiatives and ensure that they are conserving as much energy and reducing their carbon footprint as much as possible. This will be done by analyzing the current energy uses for lighting, heating, etc., the waste being produced and where it could potentially be recycled, and the outsourcing of ingredients for the actual brewing process.
