Heat transfer of uncoated and nanostructure coated commercially micro-enhanced refrigeration tubes under pool boiling conditions
The heat transfer performance of commercially produced micro-enhanced tubes with and without a nanocoating was investigated under pool boiling of saturated refrigerant. These multiscale enhancements were on the outside of 19 mm horizontal copper tubes heat ...
Oxford2023Fractures Thermal Energy Storage (FTES)
This project aims at designing a laboratory-scale experiment to investigate the thermal performance of Fractures Thermal Energy Storage (FTES) systems. While previous field tests have focused on creating horizontal planar fractures at shallow depths, none ...
2023Extension of GeN-Foam to departure from nucleate boiling prediction and validation against the OECD/NRC PSBT benchmark
Carlo Fiorina, Yuhang Niu, Hao Qin
The prediction of departure from nucleate boiling (DNB) has always been a crucial aspect of thermal-hydraulic codes for the analysis of Light Water Reactors. In this paper, GeN-Foam, a multi-physics code developed based on OpenFOAM, has been enhanced to in ...
Lausanne2023Extension of GeN-Foam to modeling of boiling water and validation against the OECD/NRC PSBT benchmark
Carlo Fiorina, Stefan Radman, Ran Zhang, Hao Qin
The OpenFOAM-based GeN-Foam solver has recently been extended to allow simulating water boiling based on a porous-medium approach. This paper describes such extension and preliminarily validates it based on the OECD/NRC PSBT benchmark. Three benchmark exer ...
ELSEVIER SCIENCE SA2023Simulation and experimental validation of pulsating heat pipes
John Richard Thome, Jackson Braz Marcinichen, Philippe Aubin, Filippo Cataldo
The one-dimensional transient numerical code of JJ Cooling Innovation has been significantly improved to simulate the thermal/hydraulic performance of pulsating heat pipes (PHPs). Using a mechanistic approach, the liquid slug and vapor plug flows and their ...
PERGAMON-ELSEVIER SCIENCE LTD2021Characterizing human mobility patterns in rural settings of sub-Saharan Africa
Andrea Rinaldo, Theophile Mande, Francisco Javier Perez Saez
Human mobility is a core component of human behavior and its quantification is critical for understanding its impact on infectious disease transmission, traffic forecasting, access to resources and care, intervention strategies, and migratory flows. When m ...
eLIFE SCIENCES PUBL LTD2021Optimum ratio of hydrophobic to hydrophilic areas of biphilic surfaces in thermal fluid systems involving boiling
Luis Guillermo Villanueva Torrijo, Tom Larsen, Ahmad Reza Motezakker
Pool boiling has a high heat removal capability and is considered as one of the most effective cooling methods due to utilization of latent heat of vaporization. Surface wettability plays a key role in boiling heat transfer since it controls the contact li ...
2019Numerical Simulations of Pulsating Heat Pipes, Part 1: Modeling
John Richard Thome, Jackson Braz Marcinichen, Philippe Aubin, Raffaele Luca Amalfi, Filippo Cataldo, Brian Paul D'Entremont
The pulsating nature of a closed loop pulsating heat pipe (CLPHP) makes the prediction of its thermal-hydraulic performance extremely challenging. Unfortunately, the design of CLPHPs is still quite an empirical process, requiring testing of many prototypes ...
IEEE2019Fundamental Issues, Technology Development, and Challenges of Boiling Heat Transfer, Critical Heat Flux, and Two-Phase Flow Phenomena with Nanofluids
This paper presents a comprehensive and critical review of studies on nucleate pool boiling heat transfer, flow boiling heat transfer, critical heat flux (CHF), and two-phase flow phenomena with nanofluids. First, general analysis of the available studies ...
TAYLOR & FRANCIS INC2019Experimental characterisation of the thermohydraulic performance of a micro-pin fin evaporator: Heat transfer, flow visualization and modelling
The global tendency towards miniaturization driven by the microelectronics industry is pushing system density and packaging towards unprecedented values of thermal design power, with a dramatic reduction of the surface area of the devices. Vertical integra ...
