Effluent Dispersion

Energy Efficiency and Effluent Dispersion

Effluent dispersion at the laboratory's exhaust vent consumes energy in two ways: dilution of effluent and creation of the necessary effluent exit velocity. Engineers must consider the height of the exhaust stack to optimize its combined effect with the exit velocity. In addition, the facility's ventilation air intake location influences stack design and placement, thus, it's energy impact. Wind modeling, as outlined below, provides the best tool for analyzing the exit velocity and the stack height interaction. [Rock, 1999]
