TEXT: A steady two-dimensional yawed cylindrical wing is
considered. The flow in the boundary layer is assumed to be
laminar,1while the temperature of the wing surface, Prandtl number
and specific heat are taken to be constant. Suffix: o denotes
conditions at the outer edge of the boundary layer. The system of
coordinates is as shown in Fig.I. With the above assumption,
all parameters of the flow in the boundary layer depend only on
x and y, while at its outer edge they depend only on x. The
relevant equations of flow are given in Eq.(l) to.(6) with the
boundary conditions as followst V~
1) U - v = w.= 0, T = Sw = const at y =~O (i.e. on the wing surface)
2) u = Uo(x), w = W - const, T = To(x) at y4eD (i.e. at the
outer edge of the boundary layer).

layer is assumed known and the variation of viscosity With
temperature is that.recommended in Ref-3 and is given by Eq.M,
where TN denotes the partial stagnation temperature (with the
CoMponen?o UO only brought to zero) while T. is a constant,
C =119*C for air). Near the leading edge of the wing UO is
small hence it is assumed that the last two terms in Eq.(4) may be
neglected and that the temperature and density at the outer edge of
the boundary layer are those given by the partial stagnation
= .0 X). Following Ref.4,, the
conditions (i.e. To = T31 , 00

coordinate y is transformed into 11, whence Eq.(8) to (11) are
obtained. If it may be assumed that JPo/.P = I then Eq.(Il) is
superfluous and the velocity field will be the same as for the
incompressible fluid (see Ref-5), and is' S-iven by Eq.(12) to (14)
plus (15) to (18) to evaluate functions f and g. Changing the
variable q to 'f in Eq.(Il) leads to Eq.(1,9) with the boundary
conditions: ;F = Yw - const when :f = 0 and T - .1 when J-* cc.
This partial non-homogeneous equation is solved by means of

separation of variables, Eq.(20). The heat flux from the gas to
the wing is given by Eq.(21). Differentiating Eq.(20) with
respect to I gives Eq.(22), which for Prandtl number of 0.6 to I
may be approximated by Eq.(23). Introducing this relation in
Eq.(21) results eventually in Eq.(25)- For Pr = I this reducesto
Eq.(26). Compared with resiilts of Reshotko (Ref.2) within the
