Mechanisms Of Boiling In Microchannels: Critical Assessment

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 ...

A novel time strip flow visualisation technique for investigation of intermittent dewetting and dryout in elongated bubble flow in a microchannel evaporator

John Richard Thome, Navid Borhani, Bruno Agostini

A flow visualisation study of flow boiling of R245fa in silicon multi-microchannels at low mass flux and moderate heat flux has been carried out with a high speed digital camera. The micro-evaporator had 67 channels of length 20 mm, width 223 mu m, and hei ...

Saturated critical heat flux in a multi-microchannel heat sink fed by a split flow system

John Richard Thome

An extensive experimental campaign has been carried out for the measurement of saturated critical heat flux in a multi-microchannel copper heat sink. The heat sink was formed by 29 parallel channels that were 199 mu m wide and 756 mu m deep. In order to in ...

Critical heat flux in multi-microchannel copper elements with low pressure refrigerants

John Richard Thome, Jung Eung Park

New saturated critical heat flux (CHF) data have been obtained experimentally in two different multi-microchannel heat sinks made in copper with three low pressure refrigerants (R134a, R236fa, R245fa). one of the test sections has 20 parallel rectangular c ...

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 ...

Flow boiling heat transfer of R134a, R236fa and R245fa in a horizontal 1.030mm circular channel

John Richard Thome, Chin Lee Ong

This research focuses on acquiring accurate flow boiling heat transfer data and flow pattern visualization for three refrigerants, R134a, R236fa and R245fa in a 1.030 mm channel. We investigate trends in the data, and their possible mechanisms, for mass fl ...
