Abstract
The objective of this study is to investigate an entrance region of thermal field in turbulent boundary layer having thermal stratification by means of direct numerical simulation (DNS), which conducts the spatially developing boundary layer with heat transfer using the generation of turbulent inflow data method. In this study, present DNS clearly provides a fundamental and characteristics turbulent statistics in an entrance region of thermal field in turbulent boundary layer having thermal stratification, in which four conditions of thermal stratification are set, i.e., neutral, unstable, weak stable and strong stable thermal stratifications.
