Eckert number : ウィキペディア英語版 | Eckert number
The Eckert number (Ec) is a dimensionless number used in continuum mechanics. It expresses the relationship between a flow's kinetic energy and the boundary layer enthalpy difference, and is used to characterize heat dissipation.〔http://www.cchem.berkeley.edu/gsac/grad_info/prelims/binders/dimensionless_numbers.pdf〕 It is named after Ernst R. G. Eckert. It is defined as : where * ''u'' is the local flow velocity of the continuum, * ''cp'' is the constant-pressure local specific heat of the continuum, * is the difference between wall temperature and local temperature. ==References==
