Thermohydraulic Performance and Entropy Generation of a Triple-Pass Solar Air Heater with Three Inlets

open access: yesEnergies, 2021
In this paper, a triple-pass solar air heater with three inlets is analytically investigated. The effects of airflow ratios of the second and third passes (ranging from 0 to 0.4), and the Reynolds number of the third pass (ranging from 8000 to 18,000) on

Development of software for the thermohydraulic analysis of air coolers [PDF]

open access: yesHemijska Industrija, 2003
Air coolers consume much more energy compared to other heat exchangers due to the large fan power required. This is an additional reason to establish reliable methods for the rational design and thermohydraulic analysis of these devices.

Evolution of contact resistance and coupling loss in prototype ITER PF NbTi conductors under transverse cyclic load [PDF]

open access: yes, 2003
Cyclic energizing of a magnet coil with Cable in Conduit Conductors (CICC), as for fusion applications, results in an anomalous change of the interstrand contact resistance (R/sub c/) and coupling loss (n/spl tau/) due to the alternating transverse ...

DNS-BASED THERMOHYDRAULIC ASSESSMENT OF ARTIFICIAL ROUGHNESS SURROGATES

open access: yesProceeding of International Heat Transfer Conference 17, 2023
Engineering-related surfaces are commonly rough to different extent. In contrast to smooth surfaces, turbulent flows over rough surfaces exhibit enhanced heat and momentum transfer in the near-wall region due to surface undulation. A long-standing research question in this field is how to predict the roughness effect based solely on its topographical ...

Influence of the outlet air temperature on the thermohydraulic behaviour of air coolers [PDF]

open access: yesHemijska Industrija, 2003
The determination of the optimal process conditions for the operation of air coolers demands a detailed analysis of their thermohydraulic behaviour on the one hand, and the estimation of the operating costs, on the other.
