Dewetting from Amphiphilic Minichannel Surfaces during Condensation
ACS Applied Materials & Interfaces, 2020Condensation heat transfer can be altered significantly by changing the texture and material of a surface to promote droplet removal and therefore lower thermal resistance. These designs are often expensive and fragile, however, and are fabricated using micro- or nanoscale features that are not easily implemented in real-world systems. Here, we present

Numerical Investigation of Turbulence Models for Minichannels
ASME 2010 8th International Conference on Nanochannels, Microchannels, and Minichannels: Parts A and B, 2010Due 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, 2003When 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 ...

Condensation Heat Transfer Inside Multi-Port Minichannels
ASME 2nd International Conference on Microchannels and Minichannels, 2004In this paper the experimental heat transfer coefficients measured during condensation of R134a and R410A inside multiport minichannels are presented. The need for experimental research on condensation inside multiport minichannels comes from the wide use of those channels in automotive air-conditioners.

Numerical Simulation of Heat and Flow of Liquid Through Minichannels
ASME 4th International Conference on Nanochannels, Microchannels, and Minichannels, Parts A and B, 2006In this paper the heat transfer and flow in minichannels was investigated by using CFD methods. The numerical simulation results show that the equivalent diameter has little influence on resistance coefficient in the laminar region. In the turbulent flow region, the resistance coefficient decreases with the increasing of the equivalent diameter. In all

A Critical Review on Condensation Heat Transfer in Microchannels and Minichannels
Journal of Nanotechnology in Engineering and Medicine, 2014Condensation in microchannels and minichannels is widely used in small devices such as air-cooled condensers for the air-conditioning and automotive industry, in heat pipes, thermosyphons and other applications for system thermal control. Currently, many research centers all over the world are dealing with the structure and operation of compact ...

Cylindrical Oblique Fin Minichannel Structure
2014A novel cylindrical oblique fin minichannel heat sink, in the form of an enveloping jacket, is proposed to be fitted over cylindrical heat sources. This chapter provides a description on the numerical simulation and experimental investigation for both conventional and cylindrical oblique fin minichannel, a similarity analysis and parametric study for ...
