The study is emphasized on the effect of CFD Mesh to the pressure coefficient and axial velocity around the bubble. A rigid sphere with the radius of 0.00575 m using flow velocity of 0.0067 m/s was considered in this study. Experimental and simulated data obtained by other researchers in the similar study were used to validate the simulation results from the computational fluid dynamics model. © (2013) Trans Tech Publications, Switzerland. %Z cited By 0; Conference of 2013 2nd International Conference on Advanced Materials Design and Mechanics, ICAMDM 2013 ; Conference Date: 17 May 2013 Through 18 May 2013; Conference Code:100296
