Implementation of the mechanistic wall boiling model in IC engine cooling gallery simulation
MATEC Web of Conferences, 2018 The ever increasing power rates of modern IC engines pose a great challenge for maintaining the optimal temperature conditions. The current trend in the thermal management of IC engines is to utilize the limited and controlled nucleate boiling to achieve

Walks of bubbles on a hot wire in a liquid bath
, 2016 When a horizontal resistive wire is heated up to the boiling point in a subcooled liquid bath, some vapor bubbles nucleate on its surface. Traditional nucleate boiling theory predicts that bubbles generated from active nucleate sites, grow up and depart ...

Gravity independent subcooled flow boiling heat transfer regime
Experimental Thermal and Fluid Science, 2004 Abstract Using an existing model for vapor bubble detachment, a subcooled flow boiling regime was identified where vapor bubble dynamics are independent of the gravitational field. The Jakob number and a dimensionless flow parameter were used to identify the boundaries of this regime.

Subcooled boiling incipience on a highly smooth microheater
International Journal of Heat and Mass Transfer, 2006 Abstract Subcooled boiling incipience on a highly smooth microscale heater (270 μm × 270 μm) submerged in FC-72 liquid is investigated. Using high-speed imaging and a transient heat flux measurement technique, the mechanics of homogeneous nucleation on the heater are elucidated.
