A test technique was developed by which stack-gas flow patterns can be predicted from tests in the circulating-water channel. Tests were conducted with a model of the superstructure of LSD28. It was determined that increased stack height andor increased gas velocity is required to eject the gas beyond the turbulent boundary zone. Tests were conducted also with models of the superstructures of LSD28 and LSD32-35 fitted with TMB-designed stacks. The flow was observed to be acceptable with gas velocities in excess of twice the relative wind velocity. Author
