Seminar - Some Aspects of Multiphase Flow Research by Prof Raymond Lau

Date: 30 September 2015 (Wednesday)

Time: 11:00 am – 12:00 pm

Venue:EF305, The Hong Kong Polytechnic University


Many industrial processes involve the operation of multiple phases of gas, liquid, and solid. The complex interactions among the gas, liquid and solid can post challenges in measurement and characterization of the system properties especially under extreme operating conditions. Bubble column reactor is one multiphase system that is widely used in chemical, petrochemical and biochemical industries. This talk will touch on the characterization of bubble size distribution, and the liquid weeping problem that is present in bubble column operations. The use of gas-solid operations in the separation of heavy metals in incineration bottom ash will also be reported.


Dr Lau is an associate professor in the School of Chemical and Biomedical Engineering at Nanyang Technological University in Singapore. He received his Ph.D. degree in Chemical Engineering from the Ohio State University. He currently serves as the associate editor of Advanced Powder Technology by Elsevier Science. He has a wide research interests from various applications of multiphase flow processes in powder technology, pharmaceutical engineering and microalgae cultivation and processing.
