| The fluid mechanics relating novel oscillatory flow micro reactor Harvey Mackley Reis Teixeira Vicente Department Chemical Engineering University Cambridge New Museum Site Pembroke Street Cambridge Phone Fax Centro Engenharia Biol gica Universidade Minho Campus Gualtar Braga Portugal Phone Fax Keywords continuous micro reactor oscillatory flow PIV numerical simulations Introduction novel continuous reactor based the oscillatory flow technology composed diameter tubes with smooth periodic constrictions presented new technology for reaction engineering applications particularly those involving screening solid catalysts Experimental studies using Particle Image Velocimetry PIV technique showed that this micro reactor improves fluid mixing and also able keep polymer bead supported catalysts with wide range sedimentation velocities completely suspended Results from and numerical simulations performed Fluent exhibit semi quantitative agreement with the experimental data Further experiments allowed conclude that gas bubbles retention can prevented configuring the tubes appropriate angles single reactor consisting series tubes can configured perform sequential reactions keeping different particles suspended different parts the reactor Potential application areas for this novel reactor are specialist chemical manufacture and high throughput screening Materials and Methods The micro reactor consists cm long and internal diameter glass jacketed tubes provided with smooth periodic caviti | |||||||||||||
