Heat transfer coefficient predictions were then obtained using each one of the modifications to determine its effect. Results indicated that the modifications made to the wall function can significantly affect the prediction of heat transfer coefficients on turbine blades. The improvement in accuracy due...

Wall y+, heat transfer coefficient #1 crevoise Member Join Date: Oct 2011 Location: Thessaloniki, Greece Posts: 75 Rep Power:15 Hello I am investigation heat transfer from a flow through a pipe with solid. The fluid and the solid are initially at 900K and the flow is at 900K. ...
A time-dependent coefficient of heat transfer is proposed for the computation of thermal power required, so that a room temperature reaches a desired value within a given time. A mathematical formulation of the room heating transient phenomenon is constructed in a dimensionless form. Using an integr...
Especially heat transfer coefficient of the walls of No.12 and No.13, when they were used in more cold areas, the energy-saving effect was significant. 尤其是12号和13号墙体,有效传热系数<0.3 W/(m2·K),用于严寒地区,节能效果显著。 参考来源轻型木结构住宅节能与墙体传热研究 墙片-引用次数:23...
