- •
The role of key flow parameters on microchannel slug flow boiling is assessed.
- •
Slug flow bubble dynamics and heat transfer performance are examined in detail.
- •
Heat transfer is enhanced by smaller channels and larger bubble frequency.
- •
Bubble frequency yields nucleate-boiling-like heat transfer dependence on heat flux.
- •
Nine dimensionless parameters govern heat transfer in microchannel slug flow.
