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. 

This project’s objective is to prototype a high-flow nebulizer that is capable of vaporizing 5 mL of medication in a 60 second treatment. After extensive research & testing of numerous existing nebulizers, we have chosen to develop two nebulizers. The first nebulizer uses vibration to push the medication through a tiny perforated mesh plate. The second nebulizer vibrates the medication directly as produces mist. These two systems are affectionately called the “mesh” & “ultrasonic” nebulizers; we are developing 2 independent prototypes for each of these methods.

This paper reports the design of an 80 MW Wind Farm in Marfa, TX. I have selected a group of the Siemens SWT-2.3-108 turbines for the moderate winds felt in Marfa (as compared to the Texas panhandle). A layout is developed to reduce wake losses and satisfy noise & environmental constraints. The point of interconnection for the farm is the ERCOT transmission system. Project economics are estimated from AEP, O&M, and federal tax incentives to gauge the electricity cost and overall viability.

This project proposes the design and implementation of a net-zero energy home in Fort Worth, Texas, powered primarily through solar energy. The objective is to offset all annual household electricity consumption through on-site renewable generation. Based on average yearly usage, the average home requires approximately 13128 kWh of electricity per year. To meet the demands, the system incorporates a solar photovoltaic (PV) array sized to generate a sufficient amount of power to offset the full electricity usage per year, sending energy back to the grid when the amount generated exceeds the demand, and supplementing energy from the grid when the demand is higher than the supply. The design accounts for seasonal variation in solar irradiance typical of North Texas. This model demonstrates the feasibility of sustainable residential energy independence in the Fort Worth region.
