Compressors, combustors, and turbines are first studied individually, and then concurrently as in a helicopter gas turbine engine. Relationships among such parameters as efficiency, power input or output, mass flow rate, temperature, and pressure changes are evaluated. Emphasis is placed on the students' ability to communicate their results in both written and oral reports. In the laboratory, physical processes and types of equipment covered i n lecture material are demonstrated by running the equipment under typical operating conditions. Data are obtained using computerized data acquisition systems in addition to manual techniques.
Students learn to write their own data acquisition software.
Each major facility can be used for several differen t tests. Other resources include commercially available software that is used to perform heating and cooling load calculations on buildings, size ductwork and piping, and assist with equipment selection. In addition, software developed by students in the labora tory can be used to simulate airflow in rooms, simulate a variety of heat pump and refrigeration cycles, and perform cycle analysis using a variety of traditional and environmentally safe refrigerants. The purpose of this laboratory course is to introduce students to the principles and techniques of aerosol measurement. The term aerosol refers to solid or liquid particles dispersed in a gas.
