Figure 2 Absorption Coefficient of Ir Led vs Pressure

As part of this work, we are talking with Solar Turbines, Inc. (San Diego, CA) about performing tests with the LED in one of their pressurized test cells, to characterize the mixing performance of a production lean premixed fuel injector. These tests will make use of a pressurized optical access test rig that Solar Turbines has recently installed. With our past experimental results showing that the LED absorption by methane is improved at higher pressures, it is thought that performing tests at these high pressures would be ideal for the infrared LED.
