摘要
水力空化通过气泡溃灭释放的高温、高压及微射流效应强化传质。研究阐明空化数、温度、压力及黏度的非线性影响:空化数降低促进空化;温度升高增强成核但削弱溃灭强度;压力需平衡溶解与空化;高黏度抑制能量释放。对比主流装置表明,旋转空化器有工业化潜力。当前挑战集中于机理复杂性、材料耐蚀性等。未来可结合仿生设计、多技术协同及重油减黏等方向突破,推动规模化应用。
Hydraulic cavitation strengthens mass transfer through high temperature,high pressure and microjet effects released by bubble collapse.The nonlinear effects of cavitation number,temperature,pressure and viscosity are studied.The reduction of cavitation number promotes cavitation;Increasing temperature enhanced nucleation but weakened collapse intensity.The pressure needs to balance dissolution and cavitation;High viscosity inhibits energy release.The comparison with the mainstream device shows that the rotary cavitation device has potential of industrialization.Current challenges focus on the complexity of mechanisms,corrosion resistance of materials.In the future,breakthroughs in bionic design,multi-technology collaboration and heavy oil viscosity reduction can be combined to promote large-scale applications.
