The flow is laminar, with uniform properties. The non-linearity
of the temperature profile is due to viscous dissipation.
The solution should be: u/uwall = y/ywall;
(h-hzero)/(hwall-hzero) = y/ywall + H*(y/ywall)*(1 - y/ywall)
where: H = 0.5 * Prandtl No * uwall**2 /(hwall -hzero)
In this case, H = 1, which implies zero heat flux at the moving
wall. The numerical calculations conform completely with the
analytical solution.
