Abstract

The novel exhaust air energy recovery turbine generator is designed to recover part of energy from a fan-powered exhaust air system which represented by a cooling tower. The discharge wind from the cooling tower varies throughout the radius makes it a non-uniform profile. A vertical axis wind turbine (VAWT) is placed at the outlet of a cooling tower to recover the energy. The VAWT behavior in the non-uniform wind stream from the exhaust air system is studied by experiment and double multiple stream tube (DMST) theory. A novel application of the DMST model is applied for non-uniform wind stream. The experimental results show that best horizontal position of the VAWT is at a distance of about 2/3 of the outlet radius with respect to turbine rotation. Theoretical analysis explains the wind turbine behavior in the non-uniform wind stream as acquired from the experiment. For the selected wind turbine, it is the best to match the highest wind velocity region to the wind turbine at the range of 45° to 115° azimuth angle. This innovative system has a huge potential due to wide application of exhaust air system globally.
