This study aims to dehumidify and increase power-saving through the suction technique, studying the effects of hole locations and angles on wetness loss, power-saving, and erosion rate. The modified model shows significant improvements in wetness loss and power-saving compared to the original model.
Nowadays, the presence of droplets in industrial devices such as ejectors, turbine blades, and nozzles causes the reduction of efficiency and reduces the life-cycle of the device by the erosion of walls. The wet steam model is validated by the experimental data. The purpose of this study is to dehumidify and increase the power-saving via the suction technique. To create suction, a hole has been used in the divergent section of the nozzle. The effects of the hole locations and angles are studied using the criteria of wetness loss, power-saving, and erosion rate. Furthermore, another nozzle is applied to the validation of the suction technique, due to lack of experimental data about suction technique. It is shown that the modified model has less wetness loss up to 6.5 % compared to the original mode. The modified model has also been numerically analyzed, showing that it has also led to a 1.22 kW increase in power-saving. In addition, it has caused a reduction of 6 %, 1.52 %, 0.41 % and 6.9 % in the erosion rate ratio, droplets radius, max nucleation rate and liquid mass fraction ratio compared to the original mode, respectively.
