    Title: Forced convection heat transfer in low Prandtl number turbulent flows: influence of axial conduction
    Authors: Shong-Leih Lee
    教師: 李雄略
    Date: 1982
    Publisher: Chemical Institute of Canada
    Relation: CANADIAN JOURNAL OF CHEMICAL ENGINEERING, Chemical Institute of Canada, Volume 60, Issue 4, Aug. 1982, Pages 482-486
    Keywords: convection
    pipe flow
    turbulence
    Abstract: The effect of axial conduction was investigated for turbulent heat transfer in a round pipe with uniform wall temperature. Exact solutions were obtained by using the method of separation of variables for the two cases with and without the axial conduction term. The solutions show that the effect of axial conduction is important at low Peclet numbers, say Pe<100, but negligible in the thermally fully-developed region. Also, the fully developed Nusselt numbers depend only on Reynolds number at low Peclet numbers and the interpolation formula is proposed: Nu∞=2.77 Re0.0656 which fits the calculated data well in the liquid metal range 0.001<Pr<0.022 for Pe<100
