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 ...
heat transfer coefficientnumerical simulationinverse problemIn the steam generator of a sodium-cooled fast reactor, high-pressure water flows inside heat transfer tubes while liquid sodium flows on the shell side. Heat is exchanged through the tube wall. When the tube fails, water vapor leaks into...
Overall heat transfer coefficientHorizontal-tube falling filmDesalinationIn this paper, two sets of experimental devices have been established for studying the falling film evaporation outside a horizontal tube and condensation inside a horizontal tube, with three different tube arrangements and seawater as...
摘要: Steam condensation heat transfer coefficient (HTC) in a large, flattened tube with variable heat flux, wall temperature and inclination angle is determined experimentally. The condenser tube is that used in air-cooled condensers for power plants. The steel tube has an elongated-slot cross se...
heat transfer coefficient. The blue, red and green lines indicate the high, middle and low monoetilenglicol flow rates in the experiment. When compared to a non-finned tube, the finned tube did not reach turbulent flow. The fins provide additional surfaces for boundary layers to form and ...
Re: Heat Transfer Coefficient #5 Alberto Schroth Guest Posts: n/a In my problem, my geometry is a closed tube with an inlet boundary condition described by an UDF which varies the velocity as a function time (sin[wt]). All the walls are adiabatic except for the end of the tube which...
Advantages: high heat transfer coefficient, compact structure and detachable structure. Disadvantages: small processing capacity, low operating pressure, less than 1.5 Mpa, operating temperature can not be too high. 3. Fin Heat Exchanger (1) Finned-tube heat exchanger ...
They found that the average Nusselt number decreased as the number of tube row increased from 1 to 6. The number of tube row has a small effect on the average heat transfer coefficient as the row numbers became greater than 4. Madi et al. [8] studied the performance of 28 samples of ...
Heat transfer coefficient is increased by incorporation of grooves on the outside of steam condensation tubes. The grooves can be vertical, spiral or curved, and are 0.3 to 3 mm wide and 0.3-3 mm deep. The depth and width are pref the same. ...
