This project explores the design of a grid independent community in Fort Worth with 200 houses using only solar and wind energy sources. Data for the project has been obtained from Dr. Michaelides, which includes excel spreadsheets and research to aid in finding optimal efficiencies in the design of buildings. The design will include energy production, usage, and storage. We are planning on using one small wind turbine with supplementary solar power; we will also be able to store excess energy. We will do calculations to determine how much energy needs to be stored and how large our solar panels need to be to sustain our community.

Solar net-zero energy buildings (NZEBs) are energy-efficient structures that generate as much electricity on-site as they consume over one year. This project involves designing a net-zero solar home in Fort Worth, Texas, using well-insulated construction materials, optimized building orientation to maximize sunlight, and efficient heating and cooling equipment. The home’s energy demand is met primarily by electricity produced from a photovoltaic (PV) system, while space heating and cooling are provided by a ground source heat pump (GSHP). Energy calculations and modeling are performed to estimate annual electricity consumption, determine the required PV system size, and evaluate GSHP operation. Results indicate that the home can reach net-zero energy performance under typical climate conditions in Fort Worth. This project shows that combining on-site solar generation with energy-efficient design strategies can significantly reduce residential energy use and lower environmental impact.

An analysis of the sound-producing characteristics of a tenor trombone has been initiated at TCU. Focus of the effort will be on the model Conn 44H "Vocabell" tenor trombone due to its unique rimless bell. A numerical model of the instrument using Autodesk Inventor has been created. The model was then analyzed using COMSOL Multiphysics.

Key areas of focus include understanding the interaction between the instrument's structural vibrations and the sound radiated from the bell. The "Vocabell" design, known for its unique construction and acoustic qualities, will be critically examined to assess how its geometry and material properties influence sound production and associated frequency spectrum. Radiated sound and structural vibration measurements have been conducted on the physical instrument, providing data for model correlation and validation. Once validated, the numerical model will be used to explore more advanced concepts of brass instrument design.

Ultrasonic cavitation is a critical process in industrial cleaning and sonochemistry, yet its efficiency is frequently compromised by inconsistent energy distribution. This research investigates the complex inner workings of acoustic harmonics and their influence on the cavitation field within a contained tub. While traditional systems suffer from undesirable "hot spots" and "dead zones," this project systematically examines how transducer positioning and operating frequencies govern harmonic resonance and subsequent cavitation intensity. Utilizing a controlled test tub, empirical data will be gathered through standardized measurement techniques, including aluminum foil erosion, to visualize and map harmonic wave patterns. The primary objective is to quantify the relationship between these resonant frequencies and cavitation uniformity. The findings will yield actionable design principles for optimizing ultrasonic systems, advancing our understanding of harmonic behavior to improve process efficiency and consistency in precision engineering applications.

This paper discusses the design of a 20-MW photovoltaic solar power plant near Yuma, Arizona. It presents the requirements to create such a power plant by using the efficiency of a selected PV solar cell as a parameter to determine the cost and area requirements, along with capacity factor and expected average power output throughout the year. The meteorological data used includes wind speed, temperature, solar zenith angle, surface albedo, direct normal irradiance (DNI), diffuse horizontal irradiance (DHI), and global horizontal irradiance (GHI), collected at 30-minute intervals from 2018 to 2024 sourced from the National Renewable Energy Laboratory's National Solar Radiation Database (NSRDB) at coordinates 32.08°N, 113.87°W.
