Abstract

•Sliding bubble characteristics and associated wall heat transfer in subcooled boiling flow are discussed.•Bubbles’ growth behavior, release frequency, velocity, and size distribution under sliding mode are investigated.•Sliding bubbles involve two distinct growth behaviors depending on mass flux.•Sliding bubbles move faster than local liquid at low mass flux while it becomes reversed at high mass flux.•The wall heat transfer induced by sliding bubbles is discussed in relation to the observed sliding bubble characteristics.
