dc.description.abstractExperiments were performed in two low‐turbulence wind tunnels (u∞′ < 0.1%) to determine the effects of turbulence on heat transfer from plates and circular cylinders in incompressible flow. Grid turbulence up to 6% was imposed. Heat transfer was increased about 30% in the laminar region of a flat plate and up to 70% on a circular cylinder; smaller though still significant increases in shearing stress at the wall were measured by hot wires near the surface. A phenomenological theory is given which shows good agreement with the experiment.en_US

dc.identifier.citedreferenceThe resistance of the ribbon remains constant so that the rate of heat generation is constant over the heated portion of the plate. Calculations of radiation and convection1 indicate that the deviation of the heat transfer rate from constancy is about 0.5% per in. Thus the heat transfer rate is about 12% lower at the trailing edge than at the leading edge of the heated section.en_US

dc.identifier.citedreferenceOne of the questions to be answered is whether effects, similar to those found as a function of free‐stream turbulence, can be traced to velocity fluctuations induced over the forward portion of the cylinder by the unsteady flow in the wake. As a result of auxiliary tests, employing a streamlined afterbody which effectively eliminated the oscillations due to the wake, it was concluded that the effect is negligible. The agreement of the measured results in the clear tunnel with Squire’s theory,20 as shown in Fig. 11, supports this conclusion.en_US
