Edel, Zachary, "Experimental investigation of regular fluids and nanofluids during flow boiling in a single microchannel at different heat fluxes and mass fluxes", Dissertation,

Experimental measurements of local heat tra nsfer coefficients and pressure drop are made for forced conv ection boiling and condensation for R134a-oil mixtures inside a horizontal tube. The results are compared with the experime ntal data of pure Rl34a. Average convection boiling and cond ensation heat transfer coefficients decreased about 20% at a 10\ o il mass fraction, and boiling and conde...

Due to the lack of understanding in the literature of channel height effects on forced-convection boiling and critical heat flux (CHF) in rectangular channels, experiments were performed with FC-72 at 1.36 bar for channel heights of 2, 5, and 10 mm. Boiling heat transfer from a linear array of nine discrete heat sources simulating microelectronic chips was investigated for velocity and liquid s...

This study examines the single-phase and two-phase cooling performance of a hybrid micro-channel/micro-jet impingement cooling scheme using HFE 7100 as working fluid. This scheme consists of supplying coolant from a series of jets that deposit liquid into the micro-channels. A single-phase numerical scheme that utilizes the k–e turbulent model and a method for determining the extent of the lami...

This paper is a part of a recent series of studies by the authors to develop universal predictive tools for pressure drop and heat transfer coefficient for mini/micro-channel flows that are capable of tackling fluids with drastically different thermophysical properties and very broad ranges of all geometrical and flow parameters of practical interest. In this study, a new technique is proposed ...
