 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....

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....
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....

The four more used correlations to calculate boiling heat transfer inside tubes are those from Chen [9] (widely used and considered as general, reliable in a wide range of conditions), Shah [20] (for vertical up-flow, is currently the most widely accepted one for horizontal tubes), Gungor-Winterton [21 ] (like the Chen's correlation consists of ...
