EFFECTS OF FREE STREAM TURBULENCE INTENSITY AND INTEGRAL LENGTH SCALE ON HEAT TRANSFER FROM A CIRCULAR CYLINDER IN CROSSFLOW
要約
A model has been proposed for the momentum
eddy diffusivity induced by free stream turbulence
intensity and integral length scale. The eddy
diffusivity model is applied to a cylinder situated
in a uniform crossflow in the presence of
free stream turbulence. Numerical solution of the
governing momentum and energy equations with the
proposed eddy diffusivity model yielded results
for the skin friction coefficient and the Nusselt
number. The numerical predictions of the present
work are compared with experimental data and the
agreement between the two is seen to be very good.
