Laminar filmwise condensation of flowing vapour on a horizontal cylinder
TL;DR: In this article, two-phase boundary layer equations of filmwise condensation on a horizontal cylinder are solved with an approximate method due to Jacobs, and numerical results for average coefficients of heat transfer are expressed as; Nu=χ 1+ 0·276 χ 4 FrH 1 4 Re 1 2 especially for large vapour velocity, namely for gD U ∞ 2 H ⪡ χ4 0·275 Nu =χ Re 12 where χ=0·9 1+ 1 RH 1 3

Laminar natural-convective heat transfer from the outer surface of a vertical cylinder
Fujii Tetsu,Uehara Haruo +1 more
TL;DR: For any Prandtl number and for arbitrary vertical temperature or heat flux distribution at the cylinder surface, local heat transfer coefficients are represented non-dimensionally by the following approximate formulae as mentioned in this paper.

Buoyant plume above a horizontal line heat source
TL;DR: In this article, the authors present numerical solutions for the steady laminar plume above a horizontal line heat source for Pr = 0.01, 0.03,0.1, 0,3, 0.,5, 10, 30 and 100.

A theoretical study of natural convection heat transfer from downward-facing horizontal surfaces with uniform heat flux
TL;DR: In this article, the boundary layer equations are solved by an approximate integral treatment, based on a concept of minimum boundary layer thickness which is derived from the consideration on the time evolution of unsteady flow field.
