A 100 horsepower compressor is used to fill the four large tanks with compressed air. The high-pressure air is then passed through the turbine blades at speeds that can reach transonic and supersonic speeds (up to Mach 1.4). This replicates the high-speed flows downstream of the combustor with a gas turbine engine. At these Mach numbers shockwaves become a significant source of energy loss. The P&amp;W high-speed wind tunnel allows researchers to detect these shock waves and measure losses.<\/p>\n\n\n\n<p>The wind tunnel (commissioned in 1994) has been used extensively for profile loss measurements in the past. Various high-pressure and low-pressure turbine cascades have been examined in order to study the effects of compressibility and off-design incidence on turbine aerodynamics performance. The test section of the wind tunnel allows for three-dimensional flow measurements. Experimental investigations include pressure and temperature measurements as well as surface flow visualizations.<\/p>\n\n\n\n<p>The wind tunnel is currently being expanded to include aeroacoustic studies of compressible flows at high subsonic Mach numbers. This upgrade is the result of CARIC\/CRIAQ funding (ENV 715) and will allow researchers to retrofit the facility to include aeroacoustic research.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Named in recognition of the long-established relationship between Carleton University and Pratt and Whitney Canada (PWC), the wind tunnel gives graduate students, researchers and PWC engineers the opportunity to collaborate on leading-edge turbine aerodynamics research.
