Heat transfer characteristics of a helical heat exchanger
Applied Thermal Engineering, 2012Abstract Heat transfer performance of a helical heat exchanger was investigated. The heat exchanger is composed of a helical tube with rectangular cross section and two cover plates. The ɛ –Ntu relation of the heat exchanger was obtained using a numerical method. In the analysis, the flow in the tube (helical flow) was considered to be mixed and the

A review on heat transfer characteristics of cryogenic heat pipes
Journal of Thermal Analysis and Calorimetry, 2021Heat pipes are broadly applied for thermal management of devices with high heat flux. Due to the dependency of their efficient operating range on the boiling point of the working fluids, employing special types of fluids is necessary to have applicable heat pipes at very low temperatures.

Heat transfer characteristics of a centrifugal heat sink
International Journal of Heat and Mass Transfer, 2013Abstract A novel heat sink, called a centrifugal heat sink, into which the blades of a fan are integrated between the fins, is proposed. The fan blades, based on design principles of centrifugal turbomachinery, are arranged to be placed between the fins of the circular heat sink. The rotary motion of the blades causes nearby coolant to be sucked into

Convective heat transfer characteristics of toothed leaves
Oecologia, 1982Model leaves were used to test the hypothesis that serrate leaves have more convective heat loss than entire leaves of the same average size. Convection coefficients were positively correlated with size of teeth, supporting the hypothesis. Experimental results were in close agreement with theoretical predictions, which assumed an inverse correlation ...

Statistical Identification of Satellites' Heat Transfer Characteristics
AIAA Journal, 1979A PROBLEM sometimes referred to as the backward analysis of heat transfer in a satellite is treated. Given heat quantities input and/or generated, and the component temperatures, the heat transfer coefficients (HTC) for conduction and radiation are sought.

HEAT TRANSFER AND FRICTION CHARACTERISTICS OF FIN-AND-TUBE HEAT EXCHANGERS
Proceeding of Proceedings of Symposium on Energy Engineering in the 21st Century (SEE2000) Volume I-IV, 2000Abstract An experimental study has been carried out to investigate the heat transfer and pressure drop characteristics of fin-and-tube exchangers with plate, wavy and louvered fin surfaces. In all, 36 samples of heat exchangers, including 12 plate-fin, 12 wavy-fin and 12 louvered-fin geometries, were tested. Results are presented as plots of friction

Flow and Heat Transfer Characteristics of a Novel Heat Exchanger
Volume 8B: Heat Transfer and Thermal Engineering, 2013Computational fluid dynamics and heat transfer simulations are conducted for a novel shell-tube type heat exchanger. The heat exchanger consists of tube with a narrow slot oriented in the streamwise direction. Numerical simulations are conducted for the Reynolds number of 1500.

Heat Transfer Characteristics of a Linear Solar Collector
Applied Optics, 1973The heat transfer characteristics of a linear solar energy collector are calculated as functions of dimensions, spectral quality of the selective absorber surface, optical flux concentration of the optical configuration, and thermal parameters and flow rate of the heat transfer medium.

Heat transfer characteristics of liquid nitrogen for cyclic heating
IEEE Transactions on Appiled Superconductivity, 2000Bubble formation and the critical heat flux to transit to boiling state for cyclic heat inputs have been investigated using a platinum - 0.5at% cobalt (Pt-Co) wire and a silver sheathed Bi-2223 tape, in order to evaluate the cooling stability for superconducting AC power apparatus.
