dc.description.abstract | The present study is performed to numerically
analyze the growth of a vapor bubble during flow of
water through a microchannel. The complete Navier-
Stokes equations, along with continuity and energy
equations, are solved using the SIMPLER (semi-implicit
method for pressure-linked equations revised) method.
The liquid—vapor interface is captured using the level set
technique. The microchannel is 200-um square in cross section
and the bubble is placed at the center of the
channel with superheated liquid around it. The results
show steady initial bubble growth followed by a rapid
axial expansion after the bubble fills the channel cross section.
A trapped liquid layer is observed between the
bubble and the channel as it elongates. The bubble
growth rate increased with the incoming liquid superheat,
but decreased with Reynolds number. The formation of a
vapor patch at the walls is found to be dependent on the
time the bubble takes to fill up the channel. The upstream
interface of the bubble is found to exhibit both forward
and reverse movement during bubble growth. The results
show little effect of gravity on the bubble growth rate
under the specified conditions. The bubble growth features
obtained from the numerical results are found to be qualitatively similar to experimental observations. | en_US |
