Synchronous observation of rising soluble bubble through quiescent solution

Yifu ZHANG , Shuai TIAN , Weizhong LI , Yongchen SONG ,

Frontiers in Energy 2009, Volume 3, Issue 3,   Pages 307-312 doi: 10.1007/s11708-009-0028-7

Abstract: An experimental method using computer image processing technology (CIPT) was proposed to observe and investigate the velocity, deformation, heat and mass transfer, etc. of a rising soluble gas (CO) bubble through a quiescent hot water. A model was set up to describe the behavior of the bubble in a visual experimental system in which a high-speed camera rose instantaneously with the movement of the bubble. A series of trajectory videos about the bubble were recorded by a computer linked to the camera. The trajectory, volume changes and rate of mass transfer of the bubble were obtained by the CIPT. It is found that the single bubble follows a rolling trajectory at the initial stage when there is mass transfer. With the volume decreasing, the disturbed behavior of the bubble becomes tempered. When the rising velocity of the bubble reaches the maximum, the velocity is nearly at a constant. The experimental and analysis results show that this method is useful for the research on the mass transfer and the movement of rising bubbles in liquid.

Observation of black carbon aerosol in Beijing, 2003

LOU Shujuan, MAO Jietai, WANG Meihua

Frontiers of Environmental Science & Engineering 2007, Volume 1, Issue 3,   Pages 345-349 doi: 10.1007/s11783-007-0059-4

Abstract: The objective of this study was to determine the black carbon concentration in Beijing in 2003. The aerosol properties were measured using an Aethalometer and a tapered element oscillating microbalance (TEOM) on the roof of the Physics Building of Peking University (39.99º N, 116.31º E) from July to August 2003 and from November 2003 to January 2004. The average black carbon (BC) concentrations in the summer and winter were 8.80 and 11.4 μg/m, respectively. During winter, two different cyclone cut offs were installed at the inlet of an aethalometer. The BC mass concentration in TSP, PM, and PM were obtained. The results indicated that in winter aerosol, 90% of BC exited in PM and 82.6% of BC exited in PM. The BC in PM accounted for 5.11% of the PM mass.
