Microchannel Bubble Boiling Simulation

@saleiz2019

Hi there! Your project aligns very closely with my expertise in high-fidelity CFD and phase-change modeling in ANSYS Fluent. I have a strong background in transient multiphase simulations, including VOF-based flow boiling, wall heat transfer, and micro-scale thermal systems. For your micro-channel heat sink study, I will focus on building a robust and physically consistent setup that captures bubble nucleation, growth, and departure without numerical damping. I typically use the VOF model coupled with appropriate wall boiling or phase-change modeling (depending on your reference paper) and ensure stability through careful time-step control, interface capturing schemes, and mesh refinement near the wall. Here’s how I will approach your three surface morphologies: • Generate high-quality, structured or hybrid meshes with strong near-wall resolution (y+ and interface refinement tailored for boiling physics) • Apply consistent boundary conditions across all cases to ensure comparability • Run fully transient simulations with time-step independence verification • Validate velocity profile evolution against your reference study (targeting ±10% agreement) I have previously worked on similar problems involving microchannel cooling, refrigerant phase change, and CFD validation workflows, so I understand the importance of both physical accuracy and numerical stability in boiling simulations. Looking forward to working with you. Best regards, Saleamlak Mulu Asfaw
