Fluid flow and heat transfer in a dual-wet micro heat pipe [PDF]

open access: yes, 2007
Micro heat pipes have been used to cool micro electronic devices, but their heat transfer coefficients are low compared with those of conventional heat pipes. In this work, a dual-wet pipe is proposed as a model to study heat transfer in micro heat pipes.

Heat transfer to impacting drops and post critical heat flux dispersed flow [PDF]

open access: yes, 1978
Heat transfer to drops impacting on a hot surface is examined in context of dispersions of flowing, boiling fluids. The liquid contribution to heat transfer from a hot tube to a two-phase dispersion is formulated in terms of heat transfer contributions ...

Heat transfer dynamics in the absorber plates of a flat-plate solar collector using both Fourier and revised non-Fourier analyses

open access: yesResults in Engineering
Recent years have seen an increased focus on non-Fourier heat conduction models for simulating microscale and ultrafast transient thermal processes. These models are particularly relevant in scenarios where classical Fourier theory fails to capture non ...
