What is Nucleate Boiling Correlation – Rohsenow Correlation – Definition

Nucleate Boiling Correlations – Rohsenow Correlation. The most widely used correlation for the rate of heat transfer in the nucleate pool boiling was proposed in 1952 by Rohsenow. Thermal Engineering

Nucleate Boiling Correlations – Rohsenow Correlation

Boiling regimes discussed above differ considerably in their character. There are also different correlations that describe the heat transfer. In this section we review some of the more widely used correlations for nucleate boiling.

Nucleate Pool Boiling

Rohsenow correlation

The most widely used correlation for the rate of heat transfer in the nucleate pool boiling was proposed in 1952 by Rohsenow:

Rohsenow correlation

Rohsenow correlation - nucleate boiling


  • q – nucleate pool boiling heat flux [W/m2]
  • c1 — specific heat of liquid J/kg K
  • ΔT — excess temperature °C or K
  • hfg  – enthalpy of vaporization, J/kg
  • Pr — Prandtl number of liquid
  • n — experimental constant equal to 1 for water and 1.7 for other fluids
  • Csf — surface fluid factor, for example, water and nickel have a Csf of 0.006
  • μ1 — dynamic viscosity of the liquid kg/m.s
  • g – gravitational acceleration m/s2
  • g0 — force conversion factor kgm/Ns2
  • ρ1 — density of the liquid kg/m3
  • ρv — density of vapour kg/m3
  • σ — surface tension-liquid-vapour interface N/m

As can be seen, ΔT ∝ (q). This very important proportionality shows increasing ability of interface to transfer heat.
