Research Experience
n Graduate period (2010 Now)
In this period, I major in theoretical and numerical
studies of gaseous flows and heat transfer at micro/nanoscale on four aspects
listed as follows.
Ø Effective resistance of gas flow in microchannels
ü Contributions:
(1) the effective resistance is enhanced by the wall interactions, increases
exponentially as the walls distance decreases; (2) ends effect from both inlet
and outlet also raises the effective resistance of gas flow in microchannels following a reciprocal exponential
relationship with the aspect ratio of length to height; (3) the formulation of
effective resistance can be used to correct the thermal resistance in the
general law of heat conduction.
Ø Scale effect of thermal conductance in
gas thin layers
ü Contributions:
the temperature jump and the heat inertia have effect on scale effect of heat
conduction of microchannel, but the decreased mean free path of gas molecules
by the confined space between walls may be the dominating factor to the reduction
of thermal conductivity of gas thin layers
Ø Mechanism of gas flow subsonic choking phenomenon of long microchannel
ü Contributions:
subsonic choked flow phenomenon may appear at certain ratio of inlet and outlet
pressure no matter there is sonic point at the end or not, and it is flow
resistance that leads to the subsonic choked gas flow.
Ø Monte Carlo modeling of gaseous chemical
reaction (current work)
ü Objectives:
to develop new algorithm of Monte Carlo method for gas chemical reaction and
try to reveal the mechanism of growth of grapheme.
