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 63.1o which is 3.57%.

Index Terms—CFD, flotation, rising bubble, surface mesh.
