... with DNS accuracy, meanwhile the scales of temperature fields decreasing approximately with Pr 3/2 and cannot be resolved for entire energy scalar spectra due to the computer limitations. To overcome these obstacles, filtering and damping of the highest temperature wave number modes in homogeneous...

... aspects of the flow heat transfer, not only on the dimpled surface but also on smooth wall. In all cases the thermal efficiency using les was found to be significantly larger than other heat fer augmentation techniques currently employed.

... 03 03 2009 Direct Numerical Simulation (DNS) of fully developed turbulent flow in a flume and channel was used to study the heat transfer near the wall. Two different geometries for numerical simulations of turbulent heat transfer in infinite channel and flume were used. Reynolds...
