施放深度对气泡水体携带能力影响的实验研究
Experimental research for influence of injecting depth on water volume carried by bubbles
摘要
Abstract
The rising bubble's capacity to carry water is influenced by many factors. For the lack of technologies to measure it, the investigation on influence laws of the capacity is a difficult point of gas-liquid two-phase flow research. In this paper, the concept of water carried by bubbles volume was introduced to characterize rising bubble's capacity to carry water surrounding bubbles, and the special experimental apparatus was made. The influence laws of different air injecting depth (27. 5 - 52. 5cm) on bubble's capacity to carry water were studied by this equipment with water and diesel fuel. The results show that air injecting depth will significantly affect bubble's capacity to carry water with the same air volume (20ml) and injection rate (3ml/s). The capacity will increase correspondingly with air injecting depth increasing and tend to approach stable, though in some special depth (35. 0~45. 0cm) it will decrease to a minimum. And the bubbles which are from smaller nozzle will carry more water. The conclusion will help to find optimal air injecting depth or more rational nozzle diameter, and it will be valuable in other related fields.关键词
