Abstract Computers
are
very
efficient
in
handling
the
problems
which
deal
with
iteration.
Numerical
treatment
of
the
unsteady
energy equation
is
one
sort
of
iteration.
The
convergence
of
the
unsteady
film
coefficient,
in
two
dimensional
space,
to
its
steady
state
value
has
been
deduced
by
comparison
of
the
results
of
the
exact
solution
and
the
approximate
solution
for
the
energy
equation
in
Couette
flow.
For
two
cases,
zero-initial
condition
and
the
linear
initial-temperature condition,
the
analytical
solutions
for
the
unsteady
film
coefficient
are
presented.
Effect
of
the
initial
conditions
on
the
reduction
of
the
number
of
cycles
of
calculation
has
been
investigated.
The
truncation
error
and
the
stability
criteria
are
fully
considered.
Numerical
evaluation of
the
history
of
the
film
coefficient,
temperature
field,
velocity
profile
and
the
shear
stress
at
both
walls
from
the
analytical
solutions as
well
as
the
numerical
approximation
soutions
has
been
accomplished
by
FORTRAN II programs
and
the
results
are presented
in
charts.
All
of
the
approximate
solutions
show
tendency
of
convergence.
