Abstract (Summary)

Numerical investigations of a jet in crossflow with two different coil inserts at four ratios of jet to the crossflow mean velocities were performed. The coils had a length to diameter (L/D) ratios of 2 and 11.25 and the velocity ratios, r, were 0.5, 1.0, 2.0, and 5.0. Results show when r=0.5, with coil inserts, jet penetration into the crossflow is reduced with increased entrainment near the jet outlet. Further results show that when r=2, and 5, near the jet outlet entrainments are reduced, with jet penetrating into higher elevations, before tilting in the direction of the crossflow. Comparing the results for the two coil inserts, with the shorter coil insert, higher penetration is obtained and with the longer coil, turbulent kinetic energy is increased in the near field.
