The iodine injector position influence on the COIL performance

The mixed flowfield performance, small signal gain distribution, and output power are numerically simulated by changing the position of the iodine injector with constant primary and secondary flowrate. This study shows that the mixed flowfield results worse, the magnitude of small signal gain becomes smaller, the output power gets lower, and the decay of laser intensity vs x goes slower while the position of the iodine injector moves forward alone the flow direction. 
