Gravity independent subcooled flow boiling heat transfer regime
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.
