A Model for Condensation Inside Minichannels

Heat Transfer: Volume 2, 2005
Present authors have measured heat transfer coefficients (Cavallini et al. [1, 2]) and pressure drops (Cavallini et al. [3, 4]) during condensation of R134a, R410A and R236ea inside a flat multiport mini-channel tube with a 1.4 mm hydraulic diameter. The experimental heat transfer coefficients (α) have been compared against correlations available in ...

Rivulet Flows in Microchannels and Minichannels

International Journal of Emerging Multidisciplinary Fluid Sciences, 2010
Thin liquid films or rivulets may provide very high heat transfer intensity, especially in the micro region near contact-line and may be used for cooling of microelectronic equipment or engines. The paper focuses on the recent progress that has been achieved in the understanding of the rivulet flow phenomena in micro/mini-channels through conducting ...

Hydrodynamic performance of additively manufactured minichannels

2021 20th IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (iTherm), 2021
Additive manufacturing can be used to fabricate components with complex flow channels for a variety of applications. Examples includes minichannels through with fluids flows for heat transfer applications. However, an efficient design of such systems requires a deep understanding of the thermal and hydrodynamic performance on channel surfaces.

Numerical Simulation of Condensation in a Minichannel

ASME 2009 Second International Conference on Micro/Nanoscale Heat and Mass Transfer, Volume 2, 2009
A steady-state Volume of Fluid (VOF) simulation of condensation of R134a inside a 1 mm i.d. minichannel is proposed. The minichannel is horizontally oriented and both the effects of gravity and surface tension are taken into account. A uniform interface temperature, as well as a uniform wall temperature, were fixed as boundary conditions in order to ...

Condensation of propane in vertical minichannels

International Journal of Heat and Mass Transfer, 2019
Abstract Experiments and models for in-tube pressure drop and heat transfer characteristics during condensation of propane at low mass fluxes (G = 75–150 kg m−2 s−1) in vertical minichannels (D = 1.93 mm) for two saturation temperatures (Tsat = 47 °C and 74 °C) are presented. Trends in heat transfer coefficients and frictional pressure gradients with
