CONDENSATION IN MINICHANNELS: EXPERIMENTAL INVESTIGATION AND NUMERICAL MODELING

Interfacial Phenomena and Heat Transfer, 2015
This paper presents an overview of the most recent research works on condensation heat transfer inside minichannels with halogenated refrigerants. The first part is focused on the experimental results available in the scientific literature and the effect of the main parameters (channel diameter, mass velocity, vapor quality, saturation temperature ...

Insights into Pool Boiling Heat Transfer on Minichannel Surfaces through Point and Field Measurements

ASME Journal of Heat and Mass Transfer
In this study, saturated pool boiling experiments were conducted on copper minichannel and flat surfaces at atmospheric pressure using water as the working fluid. The heat transfer performance was assessed through point measurements with a heater block,

Effect of Minichannel Cross Sectional Shape in Condensation

2010 14th International Heat Transfer Conference, Volume 2, 2010
The objective of this work is to present new condensation heat transfer coefficients measured inside a single square cross section minichannel, having a 1.18 m side length, and compare them to the ones measured in a circular minichannel. This subject is particularly interesting since most of the mini and microchannels used in practical applications ...

Subcooled Flow Boiling in a Minichannel

Heat Transfer Engineering, 2009
It has been considered that the dry-out is easy to occur in boiling heat transfer for a small channel, a mini or microchannel because the channel was easily filled with coalescing vapor bubbles. In the present study, the experiments of subcooled flow boiling of water were performed under atmospheric condition for a horizontal rectangular channel of ...

Onset of nucleate boiling in minichannels

International Journal of Thermal Sciences, 2000
Abstract Heat transfer characteristics during flow boiling in a minichannel were studied. For these investigations a thermographic measuring method was used. The axial distribution of the external wall temperature was measured, from which the internal wall temperatures and the local heat transfer coefficient are calculable.

Gas-assisted evaporation and boiling in minichannels

International Journal of Heat and Mass Transfer, 2018
Abstract This study experimentally explores the heat transfer characteristics of gas-assisted evaporation and boiling in single or two parallel minichannels under both non-boiling and boiling conditions. The liquid working fluid used is ethanol and the inert gas is helium.

Convective heat transfer of nano-encapsulated phase change material suspension in a divergent minichannel heatsink

, 2021
The convection heat transfer of nano-encapsulated phase change material (NEPCM)-water suspensions in a divergent minichannel heatsink was experimentally investigated. The mini heatsink was made of eight minichannels with a divergent angle of 1.38°.

Numerical Investigation of Turbulence Models for Minichannels

ASME 2010 8th International Conference on Nanochannels, Microchannels, and Minichannels: Parts A and B, 2010
Due to having considerably small diameters compared to the macro channels; validation of conventional models and correlations and, examination of heat transfer and flow characteristics for mini/micro channels have been an attractive subject for last decades.

Upflow Boiling and Condensation in Rectangular Minichannels

1st International Conference on Microchannels and Minichannels, 2003
When boiling or condensation occurs inside very small and non-circular channels, capillary forces influence two-phase flow patterns, which in turn determine heat transfer coefficients and pressure drop. A better understanding of the underlying phenomena would be beneficial from the perspective of optimizing the design of compact evaporators and ...
