Heat exchanger ice detection
This was a year long Clinic project at Harvey Mudd College done for Honeywell Aerospace. Honeywell is a leading manufacturer of environmental control systems for modern aircraft. The heat exchangers used in the environmental control systems are prone to icing issues which reduce overall system efficiency. The industry standard method for detecting ice buildup uses a change in pressure across the heat exchanger, but this method is only able to detect severe icing conditions.
During the course of our project, we investigated several novel ice detection methods and also constructed the liquid nitrogen cooled wind tunnel pictured above to simulate in-flight icing conditions.
