 A Comparison of Correlations for Heat Transfer from ...
Keywords: Convective heat transfer, Inclined pipes, Heat transfer correlations. 1. INTRODUCTION In the study of thermodynamics the average heat transfer coefficient, h, is used in calculating the convection heat transfer between a moving fluid and a solid. This is the single most important factor for evaluating convective heat loss or gain....
A Comparison of Correlations for Heat Transfer from ...
A review of literature on heat transfer coefficients indicated very little work reported for cross-flow pipe arrangement at various angles of inclination. In this study forced airflow at 1.1 m/s and 2.5 m/s across 2 steel pipes of diameters 0.034m and 0.049m were examined with pipe orientation inclined at 30 and 60 degrees to the horizontal position....

A general correlation for heat transfer during film ...
Heat transfer during film condensation inside pipes 555 Comparison with one or two data sets does not provide a conclusive test of a correlation. For proper evaluation, a correlation must be tested against data from many experimental studies covering as wide a range of parameters as possible.
Evaluation of Convective Heat Transfer Coefficient of Air ...
There is an urgent need for the formulation of correlations for convective heat transfer under internal flow conditions with inclined pipe orientation. The literature survey shows that the use of horizontal pipe correlations for calculating heat loss from inclined pipe orientation yields erroneous results of significant magnitude....

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 ......
9. Forced Convection Correlations
Part B: Heat Transfer Principals in Electronics Cooling MPE 635: Electronics Cooling 75 9. Forced Convection Correlations Our primary objective is to determine heat transfer coefficients (local and average) for different flow geometries and this heat transfer coefficient (h) may be obtained by experimental or theoretical methods....
