| description | Gas bubbles have been used in various industries for many years. Applications include water purification, particle removal, and aeration. Much research has been done in an attempt to achieve smaller bubble sizes and various methods of bubble generation have been considered. The authors chose to study a particular micro orifice method in their experiments. The main focus for this theme project was to develop and fabricate a micro bubble generator. As there were four parameters to be studied, a designed experiment was used to decrease the number of experiment runs. It was shown that the orientation of the orifice and the hydrostatic head were significant parameters while pressure and orifice diameter did not have major impact at the given range. Further observations show that the pressure inputs were out of range, and a better pressure gauge was required for future experiments. It was found that there was a critical maximum pressure that will generate a distribution of bubble sizes instead of a steady stream of uniform-sized bubbles. |
