Deteriorated heat transfer (DHT), or heat transfer deterioration (HTD), is characterized by the rapid increase in the wall temperature or the drop in the heat transfer coefficient compared to normal heat transfer. From: Applied Thermal Engineering, 2018 ...
aThe shell-and-tube heat exchanger is modeled using the Bell-Delaware method for the shell-side heat transfer coefficient and pressure drop. On the tube-side, the heat transfer coefficient and pressure drop are determined from empirical correlations [4,21].Fig. 1 presents the schematic of a ...
In the present study, the two-phase heat transfer coefficient characteristics of HFC-134a, evaporating inside a plate fin-and-tube evaporator with plain fin geometry, are experimentally investigated. The experimental apparatus consists essentially of a well modified vapour compression refrigeration system....
At a constant Reynolds number, the relative J factor (ratio of heat transfer coefficient to friction factor, relative to smooth tube values), had values from 0.93 to 1.16, with four dimpled tube configurations having values larger than unity. Despite the extremely simple design, this outperforms...
The objective of this experimental study is to evaluate the heat transfer coefficient outside a tube with annular transverse fins, derived from strips of copper mechanically bound and coupled outside. Water is used as the heating medium, in turbulent conditions and flowing at different temperatures ...

The effect of tube diameter on the air-side performance is significant. Larger tube diameter not only gives rise to lower heat transfer coefficient but ... A Nuntaphan,T Kiatsiriroat,CC Wang - 《Applied Thermal Engineering》 被引量: 44发表: 2005年 Modeling the Cooling Process Path of a De...
Tube digestionHeat transfer coefficientPrediction modelScaleBased on the actual production data of gibbsite refinery in Vietnam, prediction model of heat transfer coefficient is established due to the mechanism of heat transfer, which is validated by actual production data. The results show that the ...
A set of experimental facilities were set up to measure overall heat transfer coefficient of horizontal-tube falling film evaporators with triangular, rotated square and square-pitch bundles. Effect of spray density, saturation temperature, total temperature difference and inlet steam velocity on the ...
