Experimental System Development for Single Bubble Gas-liquid Mass Transfer Coefficient Measurement
Transport Phenomena is one of the core courses in the major of chemical engineering and technology.In the theoretical teaching of this course,the knowledge of mass transfer is the typical focus and the difficulty,and combining the theoretical teaching with practical teaching is a feasible way to improve the quality of teaching.An experimental system for measuring the gas-liquid mass transfer coefficient of single bubble based on cavity flow is designed,it combines the basic theoretical knowledge of mass transfer and computer image analysis technology to explore the factors affecting the gas-liquid mass transfer process.The experiment concludes that increasing the circulation volume flow rate and temperature is beneficial to gas-liquid mass transfer.It can be regarded as a useful supplement to the theoretical teaching of Transport Phenomena and can also cultivate students'scientific thinking and analysis ability of typical phenomena in chemical engineering processes.
