Using analytical methods, this report considers the effect of forces acting counter to laminar flow around heated bodies moving through water at low speeds. A cross flow is induced when a uniform horizontal stream passes along a heated semi-infinite horizontal cylinder. The cross-flow effects on heat transfer and shear stress grow as the fluid flows downstream and eventually becomes one of the dominant flow mechanisms. When the analysis applied to specifically a cylinder of one foot radius, heated to 100 F, at speeds of about four feet per second, free convection effects should be considered for distances as great as four feet from the leading edge; at about 20 feet per second, out to ten feet from the leading edge.
