Abstract

The current study deals with the rise of single air bubble both experimentally and numerically. Experimental investigations are performed using a high-speed camera (HSC). The bubble trajectory has been observed to be zig zag rather than rectilinear for a very low flow rate. Numerical analysis is done using volume of fluid (VOF) method along with level set (LS) to investigate trajectory of the single air bubble in water channel. The bubble followed a zig zag path rather than a straight rise. Numerical results are in good agreement with experimental work.
