Comparison between numerical and experimental water-in-oil dispersion in a microchannel

Desjonquères, Philippe; Ménard, Thibault; Tarlet, Dominique; Bellettre, Jérôme (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] The dispersion of water inside a flow of oil is investigated in a microfluidic device, producing a water-in-oil emulsion. The liquid–liquid flow mainly differs from those presented in existing literature through its ...
Impact of classical assumptions in modelling a microchannel gas cooler

Martínez-Ballester, Santiago; Corberán, José M.; Gonzálvez-Maciá, José; Domanski, Piotr A. (Elsevier, 2011)

[EN] Most of the current air-to-refrigerant heat exchanger models use the classic ¿-NTU approach, or some of its assumptions. These models do not account for longitudinal heat conduction in the tube and the fin, and the ...
NUMERICAL MODEL FOR MICROCHANNEL CONDENSERS AND GAS COOLERS WITH AN IMPROVED AIR-SIDE APPROACH

Martínez Ballester, Santiago (Universitat Politècnica de València, 2012-10-10)

La presente tesis se ha llevado a cabo en el Instituto de Ingeniería Energética de la Universitat Politècnica de València y durante una estancia en el National Institute of Standards and Technology (NIST). El objetivo ...
Numerical Model for Microchannel Condensers and Gas Coolers: Part I Model Description and Validation

Martínez-Ballester, Santiago; Corberán, José M.; Gonzálvez-Maciá, José (Elsevier, 2013)

[EN] The present work presents a model (Fin1Dx3) for air-to-refrigerant microchannel condensers and gas coolers, with any refrigerant circuitry. The model applies a segment-by-segment discretization to the heat exchanger, ...
Numerical Model for Microchannel Condensers and Gas Coolers: Part II Simulation Studies and Models Comparison

Martínez-Ballester, Santiago; Corberán, José M.; Gonzálvez-Maciá, José (Elsevier, 2013)

[EN] For a microchannel heat exchanger (MCHX), given the working conditions, main geometric data of the fin and tubes, heat transfer and face areas, there are multiple choices for the refrigerant circuitry and aspect ratio. ...
