Abstract—In this work, two models were developed for the
dynamics prediction of a rising bubble in the Hallimond Tube
using computational software. This study is emphasized on the
pressure coefficient prediction between different computational
software namely Star-CCM+ and Fluent. Results obtained from
simulated data were compared to each other and were validated
using the validation data. Spherical rigid solid with the radius of
0.00575 m was fixed for both of the software and the geometry
developed in the computational model was designed solely
based on the inner of Hallimond Tube flotation device. The
Reynolds number is fixed at Re=100, based on the free stream
velocity and sphere diameter. Simulated results obtained from
Star-CCM+ and FLUENT were in good agreement with the
validation data. Highest percentage of difference between
Star-CCM+ and FLUENT is observed at the vicinity of 63.1
o
which is 3.57%.
