A Mechanistic Heat Transfer Correlation for Non-Boiling ...
A mechanistic heat transfer correlation is proposed to estimate heat transfer coefficient for non-boiling two-phase flow in horizontal, slightly inclined, and vertical pipes using the analogy between friction factor and heat transfer. Local heat transfer coefficients, pressure drops and flow parameters were measured for air-water flow in a 27.9 ......

Heat transfer in Flow Through Conduits
Now, we return to the topic of heat transfer in tube flow. As we noted before, efficient heat transfer in laminar flow occurs in the thermal entrance region. A correlation for the Nusselt number for laminar flow heat transfer was provided by Sieder and Tate. 1/3 0.14 1.86 Re Pr1/3 1/3 b w D Nu L µ µ =...

COMPARISON OF 20 TWO-PHASE HEAT TRANSFER CORRELATIONS WITH SEVEN SETS OF EXPERIMENTAL DATA Numerous heat transfer correlations and experimental data for forced convective heat transfer during gas–liquid two-phase flow in vertical and horizontal pipes have been published over the past 50 years. In a study published by Kim et al. [11], a...
Correlations for Convective Heat Transfer - Heat Transfer ...
In many cases it's convenient to have simple equations for estimation of heat transfer coefficients. Below is a collection of recommended correlations for single-phase convective flow in different geometries as well as a few equations for heat transfer processes with change of phase.
Importance of Non-Boiling Two-Phase Flow Heat Transfer in ...
The validity and limitations of the numerous two-phase non-boiling heat transfer correlations that have been published in the literature over the past 50 years are discussed. The extensive results of the recent developments in the non-boiling two-phase heat transfer in air–water flow in horizontal and inclined pipes conducted at Oklahoma State University's two-phase flow heat transfer ......
