PROJECTS
Humidity Control System for a Automotive Wind Tunnel
Contributed to the development of steam generation and condensate recovery systems for humidity control within wind tunnel circuits. Delivered end-to-end design and project management for the steam boiler, steam supply piping, and condensate recovery systems.
The steam generation system featured a 0.5 MW electric boiler, capable of producing 700 kg/hr of saturated steam at 6 bar(a). This steam was supplied to distribution units within the wind tunnel and the make-up-air ducting system. Additionally, a comprehensive condensate recovery system was implemented, including a condensate pump, steam trapping stations, piping, and a condensate recovery tank.
Testing Facility Process Piping System
Collaborated on the design and consultation of a $5 million thermal process system for a climatic wind tunnel facility. Focused on optimizing key subsystems, including the chilled brine systems, chillers, and steam generation units, ensuring that all components met the required performance and reliability standards.
The chilled brine system was composed of a 1.5 MW CO2 chiller and a 3 MW ammonia chiller, designed to produce chilled brine within a temperature range of -2°C to -40°C. This chilled brine was then circulated through a finned-tube brine-to-air heat exchanger installed within the wind tunnel chamber to efficiently cool the airflow.
University Oceanic Testing Facility
Provided a comprehensive cooling system design for a wind tunnel and oceanic test facility at a university. The cooling system featured a 350 kW air-cooled chiller, equipped with two 125 HP screw compressors, to cool brine that was then used to regulate the temperature of both the air and spray water systems within the testing facility. The system included multiple pumps and control valves to precisely manage brine temperature setpoints, ensuring optimal performance and reliability.
Refrigeration Engineering Consultation
Provided expert consultation and a detailed report for the upgrade of a complete refrigeration system at an aerospace testing facility operated by a Canadian government agency. The existing system featured a direct expansion air handling unit that supplied dry air with a -60°C dew point temperature. The report focused on the design, cost implications, and environmental considerations related to upgrading the system to utilize a new low-carbon footprint refrigerant, ensuring compliance with sustainability goals and regulatory standards.
Hydronic Heating System for Wind Tunnel Testing
Designed a $650,000 hydronic system for heating compressed air in a blow-down wind tunnel testing facility. Played a key role in the design and selection of critical heat transfer components for the process piping systems, including heat exchangers, thermal storage tanks, pumps, and control valves. Leveraged advanced principles of heat transfer and fluid dynamics to ensure optimal system functionality and efficiency.
In this project, high-temperature brine was heated to 600°F and circulated through a heat exchanger to heat the process air to 457°F. Contributed to the engineering calculations and equipment selection, which included a 80 kW brine circulation heater, a 3 MW shell and tube heat exchanger, a 400-gallon storage tank, and the associated piping network, including control valves.
