Emprego de um modelo de dispersão turbulento no estudo da universalidade da taxa de dissipação da energia
(Universidade Federal de Santa Maria, 2010-08-13)
This study employed different autocorrelation functions and Maclaurin series expansions in the derivation of expressions describing the dissipation rate of turbulent kinetic energy. These expressions have the same functional ...
