Simulations of a turbulent momentum driven jet are carried out by Fire Dynamics Simulator (FDS). These simulations challenge the capabilities of FDS and identify strengths and weaknesses within its code; three bugs were discovered and new user controls were developed. Simulations show that mean and fluctuation vertical velocities and mean mixture fraction radial profiles at locations z/D=4, 15, and 30 are well-captured; however, mixture fraction fluctuations are over predicted at these elevations. Additionally mean vertical velocity predictions are artificially lower above the jet nozzle. These simulations are incorporated into the FDS validation suite.
