Experimental study on condensation heat transfer in vertical minichannels for new refrigerant R1234ze(E) versus R134a and R236fa

John Richard Thome, Lorenzo Consolini, Farzad Vakili Farahani, Jung Eung Park

Experimental condensation heat transfer data for the new refrigerant R1234ze(E), trans-1,3,3,3-tetrafluoropropene, are presented and compared with refrigerants R134a and R236fa for a vertically aligned, aluminum multi-port tube. Local condensation heat tra ...

Mechanisms of Boiling in Micro-Channels: Critical Assessment

John Richard Thome, Lorenzo Consolini

Numerous characteristic trends and effects have been observed in published studies on two-phase micro-channel boiling heat transfer. While macro-scale flow boiling heat transfer may be decomposed into nucleate and convective boiling contributions, at the m ...

Microscale Adiabatic Gas-Liquid Annular Two-Phase Flow: Analytical Model Description, Void Fraction, and Pressure Gradient Predictions

John Richard Thome, Lorenzo Consolini, Andrea Cioncolini, Chin Lee Ong

The study is devoted to the modeling of microscale adiabatic gas-liquid annular two-phase flow. The turbulent diffusion of momentum in the annular liquid film is assumed to be governed by the conditions near the channel wall, in analogy with single-phase t ...

A heat transfer model for evaporation of coalescing bubbles in micro-channel flow

John Richard Thome, Lorenzo Consolini

The current study presents a one-dimensional model of confined coalescing bubble flow for the prediction of micro-channel convective boiling heat transfer. Coalescing bubble flow has recently been identified as one of the characteristic flow patterns to be ...

Micro-channel flow boiling heat transfer of R-134a, R-236fa, and R-245fa

John Richard Thome, Lorenzo Consolini

The rapid development of micro-thermal technologies has conveyed an increasing interest on convective boiling in micro-channels. Although there is general agreement that these systems may be able to dissipate potentially very high heat fluxes per unit volu ...

Convective boiling heat transfer in a single micro-channel

Lorenzo Consolini

The current industrial need for compact high heat density cooling devices has conveyed an increasing interest on convective boiling in micro-channels. Although there is general agreement that these systems may be able to dissipate potentially very high hea ...

Heat Transfer in Confined Forced-Flow Boiling

John Richard Thome, Lorenzo Consolini, Wei Zhang

Remarkably different behaviors are found when comparing micro-scale flow boiling heat transfer data by distinct authors, even under similar experimental conditions. Such differences are almost certainly related to the complexity of confined forced-flow boi ...

On the prediction of heat transfer in micro-scale flow boiling

John Richard Thome, Lorenzo Consolini, Wei Zhang

Xu et al. have recently published a set of results for boiling heat transfer measurements in a multi- channel micro- scale evaporator for flow boiling of acetone in triangular cross- section channels ( hydraulic diameter of 155.4 mm). In the present collab ...
