**4. Summary**

The InterSection Marker (ISM) – a new type of 3D interface tracking method was used to simulate the evaporative growth and condensation of a rising vapour bubble due to convective boiling conditions. The ISM method's ability to calculate interfacial area more accurately than conventional VOF methods proved it an ideal candidate for multi-phase flow simulations involving heat and mass transfers across the interface. During the simulation, the predicted vapour bubble properties such as size, shape and velocity were compared against the past works and found to be in good agreement.
