Laminar free convection over twodimensional bodies with uniform surface heat flux
Abstract
A general analysis is presented of the steady nondissipative constantproperty laminar boundary layer flow over a twodimensional body of uniform surface heat flux situated in an infinite ambient fluid of undisturbed temperature. The analysis is then applied to a long horizontal circular cylinder. Numerical solutions to the universal functions associated with the first two terms in the derived series are given for Prandtl numbers 0.7, 1, 3, 5, 7, and 10. The results are compared with those obtained by Koh (1964) whose method is patterned after the BlasiusFrossling procedure for forced convection flow. The study reveals that Wilks' (1972) analysis concerning the external natural convection about twodimensional bodies with constant heat flux is in error.
